Yes that is correct. I find it works well in my No4 rifle but people here keep telling me to use Vitha vouri powder, saying it's more consistent batch to batch than the Nobel Sport. Problem is no one has any in stock and I believe the factory closed.
I have also heard that the Reload Swiss powder is worth a look, but again finding it locally is a problem.
Also I don't want too many variables at one time, it's to easy to loose the plot. I've just switched to Federal Match primers and also have some Semllier Bellot 180 grain orgives to test; so that's enough to be going on with.
It's nice to be important, but it's more important to be nice!

For a couple years shooting my Enfield Rifle No.4 Mk2, I have been holding to the left a couple inches at 100 yards.  Not too much of a problem, except I like 200 yards better.  Now, I was shooting kinda sorta five inches to the right.  I was annoyed after spending so much time on reloads.
Anyway, I PM'd W.R. Buchanan and had his tool in two days.  A well made tool as his pics above show.  Machinists are a persnickety lot.  A good thing, as the tool fits over the foresight protector like a glove and aligns the adjusting screws.  I followed the directions and moved the sight 2.25 MOA.
I went to the range yesterday and took the tool.  I did not need any further adjustment.  That was just luck, but, the tool would be easy to use at the range for any finite adjustments.

posting on an ancient thread here, but one question I have about the issue of “US Enfields” shooting so far off is, would it be that so many were sold here when the British government started liquidating them and several US companies would “sporterize” them?
I have a #1 mk 3 SMLE and it shoots 2 ft high at 100 yards. 
Even the 060 replacement sight won’t correct for that, so I’ll have to weld some material to it and trim to zero. 
(It is just a sporterized rifle, not a collector. No feinting please)

Just a question as I'm a bit confused

You talk about the "US Enfield", which is the No3 Mk1* but then go onto say its a No1 Mk3.

Are you talking about two different rifles or have you got the numbers mixed up, or am I mistaking what you mean by US Enfield ?

This is an interesting old thread, hadn’t see it before.

I think the discussion was about the apparent need for front sight adjustments for LEs that are in the US (not a “US Enfield”).  Presumably because US shooters have messed with the rifles, or not shooting the ammunition they were “designed” to shoot, the Mk VII cartridge.  Well, the Mk 1 SMLE predated the Mk VII Cartridge by about 6 years...  

These rifles can be made to shoot exceptionally well with bullets other than the Mk VII 174 gr flat based bullet.  And yes, that likely will require a sight adjustment.  No big deal, although it is easier to adjust the front sight on a No. 4 rifle than on a No. 1.

Cutting down the forend to make a sporter alters the pressure on the barrel from the forend, essentially remove it. The barrel needs the forend to dampen vibration to obtain good accuracy?  If the bullet leaves the barrel when the muzzle is at, or near, the top of the vibration cycle the shots will be high.

I think he's referring to the P-14, M1917 series. Those are frequently mentioned as U.S. Enfields.

Is it possible that only the rifles in the US have sighting problems, and the possible reason for this is the almost exclusive use of 'factory' ammunition as opposed the MkVII ball the rifles were designed and sighted for. Maybe it has come about from too many home gunsmiths messing with them when they didn't perform with ammo they were never intended to use?

Not wanting to derail your thread, Homer, but is there any market for a home designed sight tool anywhere but the US?

Here’s where I got my interpretation that “US Enfields” was in reference to LE’s that are in the US, not M1917 rifles.

It could be either, the description is ambiguous.

OK,,,  I think someone got their numbers mixed up. But what the hey.

To clarify, my tool fits over the Front Sight Protector on a #4 Mk1 Rifle, It won't work on an earlier #1 Mk3 as the Front Sights are completely different.


As far as this being a American Problem easily 50% of my sales go to Canada,Europe and Aus. So it's not just an American Problem. Also I am selling about 2-3 a month so there is a market for them.

If you have a stock rear sight on your gun the only way to correct windage is by moving the Front Sight,,, Period.

Since the 29" Sight Radius results in .008 = 1 MOA  Good luck drifting it, and I hope you have plenty of ammo so you can chase it all over the place, and then settle for "Close Enough?".

With my tool you can make precise movements of the sight and get it exactly right,,, easily.

Front Sights (9 ea.) are available in .015 increments or 2 MOA increments and the intention is to sight the gun in so that the POI is dead on when the rear sight is set at 200 yards which is considered the "Mechanical Zero" for the rifle..  

This is done using the known Trajectory of Standard Ball Ammunition 

The Rear Sight is calibrated to yield the proper "elevation offsets" for that Ammo/Trajectory out to 1200 yards.

Change the ammo and everything changes. 

However if the Windage is dead on at 200 yards it should not change any significant amount thruout the range of the weapon. At that point it is only affected by the Wind which is the most significant "External Factor" in long range shooting.

Trajectory is influenced "Primarily" by Velocity and Ballistic Coefficient. Other factors enter in and have been factored in for a long time. The Rear Sight on a 1873 Trapdoor Springfield had the vertical movement actually at a sight angle and not perfectly vertical. This Offset was there to correct for the Coriolis Effect of the earth turning. Unfortunately it only worked in the Northern Hemisphere and only if you were firing south to north. 



Point being they've had this stuff figured out for about 200 years now.

Hope this helps

Yes, “spin drift” does deflect the bullet as range increases.  For the rifles and bullets I shoot, I don’t see it out to 600 yards.  But, you will see a difference in RH vs LH twist barrels at 1000 yards, assuming you zeroed for 100 yards and shooting in no cross wind component.  

That is a handy tool, most certainly for the version of front sight base that does not have the reverse screw to loosen the dovetail.

britrifles:  it will work for them too, you just have to loosen the screw first.

Actually Parker Hale was the biggest Sporterizer of those guns. I have 2 #4Mk1's and one is a Mk1* Long Branch made in Canada that one had a 2 groove barrel. It now has been rebored to .35-303.

The Mk1 was made into a Parker Hale "Standard Sporter" IE: least modified.  They got the hand guards removed and the barrels left Full Length which usually meant the barrel had not been ruined by over cleaning. My other gun was a Long Branch #4 Mk1* and was converted to the "Deluxe Sporter" configuration. The barrel was cut back to 22", no doubt to get rid of the abused muzzle crown, a PH Front Sight added, and the fore end got cut back and reshaped. Sling Swivels were also added.


These guns were perfectly serviceable Sporting / Hunting Rifles and were a good value if you got a good one. They were very popular both here and in Canada in the 1950's and were priced at $65 and $75. This was during a pretty serous recession which always seems to follow in the wake of a big war, and people weren't rolling in dough and needed to hunt to put meat on the table. Especially in Canada!

Kind of like where we will be pretty soon if things don't get better.
