Trying to get a zero for my new No4 Mk2...

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I just got a brand new Fazakerley No4 Mk2 and want to get it zeroed in.  
I have some Mk7Z 1975 dated ball ammo to work with so ammo is correct to the rifle.

I have access to 25, 50, and 100 yard ranges.

It is my understanding that using a 50 yard range would approximate the POI at 200 yards as well,
so I planned to use the 50 yard range and a sight setting of "200" on the leaf sight, shooting from a bench.

When I did this, I got some really good groups out of the rifle, but they were about 4 inches low.  The windage was spot on.

Where do I go from here to get this thing dialed in?

	With a nominal (+0) foresight blade 1.00 inches above the bore centerline, the near zero crossing for a 200 yd zero is approx 20 yards with Mk 7 ammunition. Zeroing at 25 yds is close enough. At 50 yards, the POI should be 1.7 inches above the point of aim. HOWEVER, these rifles are usually sighted in with a 6 O’Clock hold on the target. With the typical 6 minute diameter target aiming mark, that means point of impact needs to be 3 minutes above the point of aim. At 50 yards, that is a total of 3.2 inches above point of Aim (POA). If your 50 yd target has a 3 inch diameter aiming mark and you aim at the bottom, you want to have a Point of Impact (POI) about 1 1/2 inches above the target center for a 200 yd zero. 4 inches low requires a 5.5 inch upward correction (4 + 1.5), 11 minutes of angle. Your choices are to simply raise the rear sight by 11 clicks or get a shorter foresight blade. Each size alters the elevation POI by approx 2 MOA. Look closely at the base of the foresight blade (you may have to remove the foresight blade and clean it so you can see the height stamp markings). You will need a blade 5 to 6 sizes shorter. Blades come in height increments of 0.015 inches, from -.045 to +.120. This is all for Mk 7 ammunition at a nominal 2440 fps. Your ammunition may not be nominal, so you can expect differences in elevation with different ammunition. I don’t bother zeroing my rifles to match the back sight range index marks, except for the No. 4 T with the No. 32 scope.

	The blade I have on it says (F) .06 on it.

	I forgot to include that I am using HXP .303 Ammo dated 1975 on the packaging as my ammo.

	A couple of things to consider. "brand new Fazakerley No4 Mk2" The wood may have dried considerably & shrunk, changing bedding. Try a few coats of RAW Linseed oil & let it soak in to get the stock wood to swell back up to normal. HXP Mk7z ammo may print slightly different from Original MkVII ball. Let the rifle settle down if it really is Brand New Unfired! run some more ammo through it to achieve this. After checking those follow Britfirles advice.

	Agree, I had similar thoughts on why this rifle is shooting so low. It would have been correctly sighted in at the factory, but that was 70-odd years ago. As a crude check, with the front trigger guard screw firmly tight (30-45 in lbs torque), press down on the barrel at the muzzle with the front of the fore-end supported. Does the barrel move before contacting the fore-end?. If it does, the fore-end has likely warped, try what Shamu said to do, raw Linseed. It might help. HXP in my experience is a bit hot, 2500 fps or more. That can have an effect on MPI, lowering the MPI due to something known as “Compensation”, the barrel is moving upwards as the bullet leaves the muzzle. Fast bullets exit the muzzle earlier at a lower angle of departure making shots hit low at short ranges. If bedding is good, and Linseed treatment does not change anything, you can change the foresight to a lower one. You would need a -.015 blade. You can find these on EBay. Buy a few different sizes, you may find you need a different size with different ammo, particularly if you reload. Please be aware, do not remove the fore-end until you know how to do so correctly. Otherwise you will damage the very important wood bearing surfaces at the sear lugs known as “the draws”.

	/\ /\ /\ This. I have a .PDF of the disassembly manual if you need one. Iti'll have to go via e-mail as its too big for the forum's file handler.

	I start re-oiling with RAW linseed oil today, then out to the range in the next few days. A thought here: I have access to a 100 yard range distance, if I drop the sight by two clicks from the 200 setting, that should approximate a 100 yard sight setting should it not?

	Yes, that’s the simplest way to confirm zero’s, other than shooting at 200 yds. Though, rise from 100 to 200 yds is about 3 minutes with Mk 7 ball ammo. All my Mk 1 aperture sights can only be lowered by 2 clicks from the 200 yd index mark. Yours might move more than that.

	I've found 4 clicks down from "2" works perfectly.
