barrel). Some guns like a-max's: you wont know until you try
different bullet types and compare your targets. I recommend
moly-coating: it improves velocity and makes barrel cleaning easier.
Loading for the AR is a little different than for the M-1. With the
AR, you will see flattened primers: that is ok: avoid blowing your
primers. You may want to consider selecting cases: commercial cases
seem to work best at 600 yards (slightly bigger case capacity).
Unlike the m-1, there isn't one magic load (i.e.: a national match
load): the accuracy comes from hard work and load development. Do
your homework and the results will show down range.
Hag: Start with 23 grains. According to hornady it's good for 2550
with their 75's you should end up with a tad over 24 for your molyed
pills. Like that TAD. Or as Derrick might say "use your 80 load and
save changing your measure". pitboss OCF 75 Gr. Hornady W/Varget
Need a starting load using the 75gr. Hornady match bullets seated to
magazine length, (Moly Coated) CCI BR-4s, LC cases and Varget. Only
for use at the 200 and 300 line. (John S. do not try to adjust your
monitor, this is only a test!) Kenny.
I have used 25.0grs w/ non-moly coated bullets, WW Primers, WW & REM
cases, seated to mag length in a Colt HBAR. I only switched to Rl-15
because of a good deal on several cans and one limited test w/scope
attached for 100m accuracy evaluations. The difference was marginal,
but the deal was substantial! Good luck. Mike
I've used 25.0 Varget in GI cases for Hornady moly 75's and Sierra
moly 80's for 600. That's where I'd END. You should be happy
somewhere in between 23.5 and 25. I've shot the 75's at 600, and
they'll do okay, but nowhere near as well as the 80's.
Dave: ditto's on the varget loads, I settled on 24.5 because more
didn't help accuracy but did noticeably increase primer flattening.
I also have a lot of crunching of powder even with vibrating the
filled cases at 24.5. How have you found the 75 a-max compared to
the 80's? My guns shoot them very well at 600 and I decided to stick
with them. I have heard one of our shooters got a very impressive
600 yard score with the 77's at MAG(!) length in his match ar - a
198 in practice. So in his gun at least, they don't mind a long
jump. Don't know how it will do for him in matches but I'll be
I was shooting the 75 NM bullets, not the A-Max's, although the
fellas I talked to that had original 1-9 twist (Armalite) guns said
the A-Max's were the Primo 600-yard bullet. I got an e-mail a while
back that said a fella won a 1,000 yard match in Wisconsin with the
Hornady 75 NM's, but they were subsonic.
