I have a very nice Korean era that I got from CMP a few years ago. I replaced the stock with a Boyd's and relieved all the rub spots and forward and rear guards. Passes the tilt test. Keeping it legal for Garand matches. Had a very fine 'smith straighten the op rod and that improved group size significantly. Very dependable.
I have to put in 19 clicks el. for a 100 yd "6" hold to hit the bull.
Any thoughts?
Does it shoot low from the very first shot or start to shoot low as the barrel warms up.
Hows the lock up?
If it consistantly shoots low the front sight may be the only answer
In the meantime, inspect/verify your rear sight that the 19 clicks is really lifting the ladder that much. Push on it with your thumb as you dial it up from the bottom. Could be a loose set screw in the elevation knob.
Only problem I found was that the firing pin tail is impacting stock at the rear. Easy fix.
But that sure can't be the problem I wouldn't think.
Any other thoughts?
Thanks in advance.

Check on CMP forum for stock fitting but on Boyds stock another contact spot is on stock itself. The barrel doesn't fit all the way down in the stock and can cause it to shoot high. Another contact spot is in trigger guard assembly, Its in the little u shaped cutout where the trigger disengages the sears. You will be able to see this as there will be a little line going across the u shaped cutout. Just relieve it and trigger will be a lot crisper.
If that is not going on, just shorten the front sight blade. Many G.I. front sight blades were shortened on active duty and it is legal for a CMP games match or any type.
Gus,
The stock is relieved and the bbl isn't touching the side of the forearm.
If I shorten the FS... Ea. .08" accounts for roughly 1 moa. If I knocked off enough to take it down to a 10 click for 100, I wouldn't have much FS left. But at least I know it would still be "legal". Ha!
One thing I did note though was that my rear sight is very tight w/ a LOT of el. dialed in.
So how many clicks up from 100 yd 0 do I need for 600 yds? Maybe I can get by anyway.
Thanks for the reply. I appreciate the help.

I know this may be difficult, but the best way to shorten the front sight is with a good file and actually on the firing line. That way you can check your progress and ensure you don't cut too much off.
If I may, I would suggest you STOP filing when the front sight has between 4 -6 clicks of elevation at 100 yards, especially the first time you try it. You NEVER want to file it so it has 2 clicks or less elevation at 100 yards as with diffierent light conditions, you may have gone too low.
Since the 200 yard line was the closest we shot NM rifles, we filed the front sight blades so there would be right at 4 -5 clicks elevation at that distance. Then, that gave as much elevaion as possible for 600 and 1,000 yard shooting. But with rifles for most people, I do the filing at 100 yards.
I'll do it at the range next time I go up there. Maybe take .072 off first and see what happens. Still be at approx. 10 clicks for 100 but I don't want that FS Too short.
Valuable info. Thanks.

SPUD,
Forgot to ask what size target are you shooting at?
Gus,
I remember targets we shot were 12" diameter bull at 200 yards. What size target should he be shooting at? It will make a difference.
I shot my new to me SA FG today. I got 16 clicks to zero at 100 yards. Shooting at a 6" bull at 100. I do know what the issues with my rifle the rear aperture hole is off center, it is cockeyed low to the left.
I'm sorry I don't remember the actual size of each bullseye at each yard line. All a NM Armorer really had to know is the X ring is 1MOA for each yard line. Grin. It would be best to look that information up on an NRA shooting site.
interesting thread, just sighted in my SG and FG CMP Garands and needed 15-16 clicks to hit center on an SR1 @ 50yds using 6 o'clock hold. I thought this seemed a bit much but switching from center hold to '6' is easier for me to define with my degrading eyesight but I chalked it up to the new sight picture.
shooting with front support only so far from a solid platform but with 15-16 clicks elev I seem to be printing at center + 1-2" above so I figured at 100yds it wouldn't be much if any at all diff POI so I set the knob to '1' for 100yd zero.
using HXP ammo, so this is considered excessive and should be 4-5 clicks up for 100yd zero? am I getting this right. checked pinion tracking all the way up and down on both rifles, everything seems positive and no unusual slop with adjustments.
