Subject: Improved group size.

I mentioned in a previous post that my No8mk1 had increased the group size after I had refurbished the wood. During my vacation I decided to investigate the problem. I found that the barrel up pressure on the barrel was excessive at over 7 lbs and the contact patch at the front fore end was off centre and the upper hand-guard was also solid on the barrel. I removed the high spot under the barrel to centre it at the front; removed some material to give a 0,010" clearance to the upper hand-guard. Fitted a shim under the trigger guard main screw (gasket paper 0,008") and also shimmed the clearance between the wrist and the woodwork which was over 0.025". The up pressure on the barrel is now 2,75 lbs. The range test was very satisfying.
The lower RH target is from a sandbag rest at 50 metres before investigating; the lower LH target was with upper guard removed. The central C50 target was 50 metres from the prone position without sandbag rest after the modifications. I was very happy with these results, this group was the 3rd test of 10 shots,(the first two groups were also good but required a little elevation).

I would mention that I found some very useful information in a book I recently purchased written by New Zealander Roger Wadham; The 2012 Complete book of Lee Enfield Accurizing. Although the book does not deal with the no8's, the methods prove useful.

Please don't forget that the size of the groups being shot, is not solely with the rifle. It is also effected by the firer...
1). Weapon holding.
2). Correct aim picture.
3). Same point of aim / line of sight.
4). Breathing control.
5). Trigger release.
6). The follow through after each shot.

Also, to achieve a correct and more accurate assessment of a group, they should be shot at 100mtrs.

Also... what I should have mentioned, is that an accurate grouping cannot be assessed, if, before adjustment, the weapon is fired supported / unsupported, then after adjustment, the weapon is fired using a different method. By doing so, inconsistencies are brought into play. The weapon should be fired both before and after adjustment by the same means = unsupported or supported. The reason for this, is due to the need to verify if the adjustment made was actually required for improvement, and if it actually made any improvement.

If one is not consistent with ones course of actions, then all one is doing is chasing... thus compounding an error.

Sarge, you are correct in your comments; After making the adjustments I should have used the same bag but needed to practice for a competition with this rifle which is next saturday, and our clubs "bag" was being used by a colleague. Here is a picture from my ammo test I did prior to removing the wood for renovation. Compare that to the groups after refitting and it is evident I had a real problem. I was happy with the group from the prone position, and our competitions are at 50 metres so thats why I train at that distance (and the fact that we don't have a longer range!!)
It seems to be back to what it was now and good enough to compete with. Just hope I do my part on saturday. My wife is using the other No8 in the same competition! so no pressureWacko

Zed...

You've just illustrated a very valid point when target shooting... either setting up prior to, or during a shoot. Never rely on others for your prone supports. A backpack with a rolled up coat is perfectly sufficient, as long as the firer is comfortable.

As your firing in the competition at '50mtrs', it makes sense to zero in at the range... if you have no space further out.

Judging by the fall pattern.. 'vertical'.. you need to perfect your breathing = breath normal up to sighting... hold ones breath when on target... squeeze the trigger... follow through.. breath normal for sighting the next shot. You should hold your breath before firing for no longer than 5-seconds. If one does not fire during that time... breath out, relax, start again. if you don't already do the above, try it dry firing = no rds, just aiming and breathing. You'll be amazed at how your grouping will improve over time.

Your use of ten rounds per sighting group seems a tad excessive, and not really necessary. Five shots is all that is required in order to estimate a group size.

Sarge, interesting what you mention with regards to the breathing issue; and I am currently working on finding out what is best for me, some people say exhale fully and hold, but I find that less comfortable than just holding a normal breath. The time issue is also important and I have to try and ensure I don't hold my breath too long; particularly when shooting from the standing position. The small calibre class in or military rifle competitions requires 5 sighting shots prone, 10 shots prone (no additional support allowed) and 10 standing for max of 200. The standing position I find hardest and I am slowly improving my technique. I had been using the sling; but this year the rules say no slings so I have to adjust my hold on the rifle to suit.

 Begs to ask the question... why mess with it in the first place? Disapprove

I appreciate the whole "it's your rifle and you can do what you want with it" thing, but did you not consider the work may have an impact on it's accuracy? And now the fix will have had a more serious impact on it's value than the work as well...

Yes, it is up to the individual, but if it ain't broke, why fix it?

IIRC his handguards were pretty messed up, appearance wise, so thats what he was inproving, the appearance.

The rifle was covered in a thick varnish, which was not original and not pretty. So I decided to strip it back to the wood and then treat with BLO. There is another thread with photos of the rifle before and after. There were no modifications and the bedding technique and adjustments used to get it back to shooting well are standard methods. It's not fixing a broken rifle, just making the most of it's potential!
I will be using this rifle for competitions so it's good to strip it, get to know what makes it work well and what doesn't. Plus, it was fun to learn something new and I'm happy with the result.

Well done in the end, though... and good luck against your misses!

Before and after pictures of the rifle concerned, it's the one in the middle; with it's sister No8 that my wife uses and my No4 mk1/2.

After the renovation of the woodwork. It's the lower one, it has the No5 type receiver.


I think the work was worthwhile and I have enjoyed the experience of working out the problems and sorting them out. It's the best way to learn.

I'm going to dive in on the seperation of shooting prowess & firearm testing for accuracy, just because its one of those things that needs repeating every so often IMHO.
 
The shooter & his ability (or lack thereof) is subject to a lot of internet discussion. Probably because the shooter is usually nowhere near a "jury of his peers" when actually shooting the group. We see the result, fequently teeny-tiny groups, but not how the group was actually achieved! Because of this I usually take unbelievable internet targets posts with a grain of salt.Tongue
 
Heres how I do the testing of a firearm, as opposed to how I shoot.
 
I use a solid benchrest, even if it is sometimes improvised & not one of those multi-adjustable cast iron thingies.
 
I have a solid front support with a small sandbag atop the support, (frequently an ammo can, because it can be turned for different heights), so as to not get any barrel bounce from firing impulses.
 
I use a bag under the heel of the stock also, which if I get it right, I can "pinch" to adjust for elevation.
 
My left (off) hand does not touch the forend at all, it is bent at the elbow & comes back to me so the hand can manipulate the rear sandbag.
 
I do not use the sling at all, except from checking it is completely loose when testing so it doesn't pull on the forend at all.
 
Breathing I do several (3~4) deep inhale/full exhale cycles, then as I set up for the shot I take a last full breath & let it out slowly till I'm not at all "strained" but reasonably & comfortably full. If I position everything right the sight drifts down across the bull as I exhale & I stop as it sits on the bull. Thats when I take up first pressure on the 2-stage trigger. Once I'm done with final minor adjustments just add pressure till the trigger breaks & follow through.
 
After every shot I reposition everything as exactly as possible. I also look away from the sights & look at anything else to relax the eyeball. I've found by loading the bloodstream with 02 fairly well in advance I have a longer "loiter time" when I actually set up to fire the test shot.
 
This shows me how the rifle & ammo perform, usually making "internet boastable" target groups, but it doesn't really say anytrhing about how I shoot as I've removed myself from the equation as much as possible.
 
Shooting is a different technique using no bag, no rest & a sling, but this shows up in the groups opening up to real world dimensions.Shocked

Shamu...
 
i think you hit the nail fairly square on the head there. All this fixed solid bench rests etc, only prove that that when everything is mechanically sound... with no human in the line, apart from loading and pulling the trigger... a very tight grouping is achieved. To my way of thinking, that method is a total waste of time. Why? it doesn't prove how the firer operates, or what their capabilities are. it still does not prove if the firer can, or cannot hit the target and achieve the required grouping or better.
 
Also, the individual is not being true to themselves. I personaly have never used a bench rest, and never will. The aim of zeroing, is to match the rifle to the firers style. This cannot be achieved by using such devices as bench rests. However, for safety reasons when bedding in new barrels, bolts, or other mechanical parts... I can see the reasoning behind such devices. But for target shooting... no. Its the individuals skills that matter at the end of the day.

Thats why I seperated out the part about shooting being different from testing the gun's abilities.
The final result is a combination of the rifle's abilities & the shooters technique & skill.
 
I test that way only when I'm trying to fix or adjust something, the rest of the time I'm slung up & (usually) prone. A BIG diffderence between shooting in the U.S. & The U.K. is the bench itself. Many ranges here ONLY allow shooting from a bench! No standing, sitting kneeling or prone.Wink
 
We also score "inwards", not "outwards" (bullet breaking a line score the lower/higher value), but that's another story!Clown

I only use the rest when I'm testing different ammo or want to test work that may effect the accuracy. As I am still quit new to this (I've only acquired the No8's in the last 6 months and the No4 in 2011) The difference between what I achieve in a test, which is the rifles potential and what I achieve when shooting normally shows me how much work I have to do!
After refitting the wood on my No8 I was using it for a few weeks and noticed my scores had dropped by a few points, and I was not sure if it was me or the rifle at first. The test confirmed there was a difference in the rifle since the rebuild and helped me to rectify that. I am sure if I had as much experience as some of you guys I would have realised it was the rifle. It's a learning curve for me, and I appreciate all the advice received.

Zed: Can you post a better picture of how you've rigged that sling with the *ahem* "King Screw Swivel"? How do you employ it with the center attached close to the stock 1/2 way down? I think I may be about to learn something!Geek

Shamu, I will take some photos of how I use the sling. It is removed from the rifle at the moment because they have banned slings from the .22 military rifle competitions this year. We are shooting tomorrow. I will put it back on afterwards and post some pic's.

Shamu, here are a couple of pictures taken on Sunday morning at the range, with the sling fitted and in use on the No8.



I'm not sure it really helps in the prone position, but it is useful when standing to help dampen the movement. Having the sling come through the centre swivel helps prevent any sideways pull of the fore end woodwork. Saying that; I had a good result on Saturday's competition without the sling (I got 4th place with 98/100 prone and 84/100 standing) my wife was not so happy without the sling, (23rd place overall  94/100 prone and 56/10 standing) and after I'd refitted it she shot a 79/100 standing on Sunday morning. So she was a bit peeved with the 56 he day before ! Especially as it turned out the referee who told us we could not use the slings was wrong, problem was Saturday I had left them at home Ermm

Thanks, thats kind of where I thought you might be going with that. Is that sling the longer one with the sewn in tabs from earlier, it seems a standard web sling might be a bit short for that trick?
 
I have the "king screw" swivel, but I'm using it with a "Ching style" double loop sling so it still puts pressure on the forend, but I've seen SLR (FAL) slings attached at the rear of the handguard so as to not put pressure on theat thin light barrel they have.

Yes these are the ones with the tabs sewn on. I have one for each No8. They would suit the no4 also, as they are almost on the shortest adjustment on these. The standard slings can slip if you start to pull on them too much.

Breth control is one thing I'm very up on, having done quite a bit of free diving when younger, achieving a full five minutes submersion at 25 ft on my best day. Scared the begezzus out of a young lady who came in to use the diving pool while I was down there, she thought she'd found a drowning victim. When she pulled up from her high dive I was there holding the bottom rung of the ladder. You would not believe the look on her face.

Anyway best practice is to breath deeply and slowly for several minutes, don't over do it or you get giddy, take a deep breath(not a lung buster, just a normal deep breath as when taking in the morning air in the country), release half that breath very slowly while getting your sight picture, then hold that half a lungful while fining down your sight picture and squeeze the trigger while dead still.
Friends say its spooky how still I get when shooting. Not a single muscle moves except heart beat and trigger finger.

PS
A placid mind is another aid when shooting. Not so much concentration as simply thinking of nothing else but the sight picture and trigger pull, no room in the mind for doubt. The less you think the less chance of overthinking and screwing up.
As in any martial art the hand, eye, and spinal cord are working faster than the mind can work. When sight picture is perfect the trigger finger gets the message from the spinal cord faster than you can think.
When there's no discernible hesitation there's no loss of sight picture.

Follow through is another factor. I suggest archery and shooting muzzle loaders to develop follow through. This is especially useful when using old milsurp ammo with varying length of hesitation on ignition. Even a few hundredths of a second variation can make a difference if you don't follow through consistently on very shot.

LE Owner,thank you very much for your advice, I will be trying to improve my technique (but not in the deep end!)
 A placid mind is something that definitely makes a difference. At my shoot last saturday I was not as calm as normal. I think this was due to a fairly major accident that happened in our workshop the day before, a colleague accidently ignited fuel vapor in the trunk of a car and the vapor remaining in the gas tank exploded, blowing him across the room, luckily it was just a loud bang and flash fire, my colleague suffered mild burns, but luckily the oxygen was consumed so quickly that it did not continue to burn, and the open 20 litre can that was just next to the car did not go up!I put an extinguisher into the trunk to make sure there was no chance of it reigniting but I spent the weekend thinking about what could have happened if he'd been covered in burning petrol. Not ideal situation to compete in a shooting match; I was surprised to get 4th place.
