C7 groupings

all depends
I had a rifle team C7A1 that was submoa - if I did my part.
However guns get beat up in the field -- plus you get morons that will scrape the muzzle crown not knowing that it will affect accuracy.
I've seen C7A2's that would not group under 10"

None of our instructors were morons. They all told us to pull through only from the chamber to muzzle. They'd kick us in the pants if we used our Gerber on anything but pulling out the firing pin retaining pin.

The C7A2's are not new rifles, look at the serial no.'s and you'll see that it's the same old rifle from the 80's. Of course some of them have been rebarreled, and for some reason, at least in my unit, it looks like most of the bolts have been replaced with new ones.
Gotta admit that I was taught to scrape carbon out of the muzzle, quit doing that years ago though.
FYI the military requirement for the rifle and ammo is 4". Most will group a lot better than that, and the odd one won't group worth a damn.

Some other Navy person must be disrespecting a rifle in that fashion, 'cause it sure ain't no-one I've trained.

Same here... like NavyShooter, I myself have conducted 100's of range practices and supervised just as many weapons cleanings.. Not once have I seen anyone aggressively cleaning the muzzle crown, and I've been using this rifle with the CF since they were brought into service in West Germany in 1989.

Science guy, you musta been there to eh?!!
I got chewed out severely one morning on inspection back when I was a kid in basic because my crown was not all pretty and shiny like my riflepartners was (read 'clean' as: 'scratched to #### with a coathanger or other available metal object')
Damn section commander from the next group over absolutley tore a strip off me. Up one side and down the other. ####er just wouldn't let up either.Now that I look back on it I can laugh my ass off... he was a 'sniper' (use lots of echo and reverb "snniiipppperrrrrr") and loved to remind everyone of it -practically every ####in day. That was many years ago but IIRC he was PPCLI. But I could be wrong. Hopefully he didn't train too many of the good kids out there in the CF the wrong way to do things.

Yeah....I did my BMQ last july and they had us chip the carbon out of the crown with the blades from our Gerbers..........
Still shot straight, but I don't think we were the first to have to do this. These C7s were from the mid 90s.
That is appalling, I think the SLR was 20 rounds in 4 groups of five to produce an overall group not exceeding 100mm. That was the minimum or you went back to training on the marksmanship principles.tekriter MK 1 said:
You then fired a check group of 5 rounds to score and the group size gave you 15% or similar of your overall APWT score. its changed now as the tupperware devil is capable of much tighter groups much further out and details are fired at 400m, where 300m was the maximum with the SLR!
