What factory ammo/ custom loaded ammo are you guys shooting? Got a buddy that just picked one up w a 22" barrel and want to give some advice on a good starting point for him. Any comments or suggestions are appreciated.

Re: Question for the M1A guys
Both of mine like 168g FGMMs which seems to be pretty common.
L
edt: BTW, what model did he get?

Super match m1a 22" heavy Douglas barrel. I believe it 1:12 twist.

Re: Question for the M1A guys
Out to about 600 I like the 168's like Layton said. Past 600 I like 175's FGMM.

Should be a 1:10. New?

Re: Question for the M1A guys
Fairly new he purchased it around 3 months ago. I will have to confirm with him on the twist rate. Do you happen to know the B.C. of the 168 fgmm by any chance? Or what kind of velocity to expect from a 22" tube?

Re: Question for the M1A guys
G1 - .427 G7 - .218
Not sure on velocity. Never chrono'd mine.

Re: Question for the M1A guys
Great info guys I will pass on all you guys suggestions to him. I'm trying to get this guy off his ass so I can have a shooting/match buddy, but work def eats up most our time. Again thanks for the help guys.

Re: Question for the M1A guys
Being a hand-loader, my M1A SM really likes 40.2 grs of IMR 4064 underneath 168 NCC's (FC brass and F210M primers) and they move at 2375 fps. I am aware that others may prefer a load that will move faster, but higher powder charges begin to show signs of high pressure on my fired cases (before handloading for M1A be sure to build up your Zediker library).
On a bench with a scope mounted this load holds .5ish MOA at 200yds. From a field position... I'm the weak link in the chain.

Heavy 22" Krieger 1-12 twist-168 gr TAP averages 2675 fps and 1-1.25 moa at 1000 yards.

Re: Question for the M1A guys
My M21 likes the 168's from American Eagle (Federal). It also likes the FGGM 168's and doesn't mind the the 175 either.

Re: Question for the M1A guys
I've been shooting a Heavy Match since the late 70s in High Power.
The standard load we used was 41.5 grns 4895 with the 168 SMK, either Winchester or LC brass, fed match primes. It pretty much matched the Federal Stuff and M852.
When we moved to 1000 we used the (old) 180 SMKs (which is about the same thing as the 175s) loaded as above.
Federal loaded ammo is OK but it sucked in reloading (pulled it apart upon extraction. That's using SB dies RCBS Competiton dies.
I pretty much lost my contacts for supplies of LC Match Brass and gone to almost all Winchester.

Re: Question for the M1A guys
Almost forgot: let us know how things work out for you guys.
But above all: be safe and have fun (you'll be a better marksman in the long run)

175s wont hurt a M1A, I've been shooting 180 & 175 SMKs in mine since 1978 and it still works.
I ran the Ak NG Rifle Program and we used 180s (before they had 175) in all our Match M14s at 1000 and sometimes at 600, They didn't hurt anything.

Re: Question for the M1A guys
175's at 2500. I use H4895, Winj brass and WLR primers.
Accurate at all ranges and wind is easy. Range in 100's (yards) X velocity and you have your basic wind hold.
An M1A will teach you that faster isn't always better

Isn't that Range in 100 yards X velocity divided by 10?????
Example: 600 yards in a 10 MPH wind would be 6*10/10 = 6 moa correction in full value wind.

I agree, I think ISU 300 meter rifle shooters found a long time ago that the 308 is most accurate at about 2200 FPS. Might need to go a tad faster in the M1A so it works the action.

Re: Question for the M1A guys
you caught me in a senior moment Kraig. DIVIDED is right.
I do the easy way for me, range in 100's as a decimal value X wind value, just didn't express it correctly.
example; range in 100's 600 yards = .6 X wind value for hold correction in moa.
Same value, different expression. I gotta be more careful with when writing math explanations!
