My data say 42.0gr IMR4895, WLR, surplus brass to duplicate M80 ball. Pretty close to what I load for the 168HPBTM (41.5grs).
I hit the range this weekend with my SuperMatch (newly rebarreled w/ a 1:12" Kreiger) and got really good results with the Speer 125gr TNT (same powder, same charge as above, 2.7" OAL). 1-1.5MoA prone w/ irons. Looks like a nice, low recoil, match-worthy load for 200-300yds. Other match shooters I've talked to say it's a good bullet for a 1:12" barrel; pretty much doesn't care about powder, charge or seating depth. Ty |

I'd probably leave the charge as is (I'm lazy), but 0.5-1.0grs more wouldn't hurt.
I was just tickled to find a 10 cent bullet that shot almost as well as a 20 cent one! |

It came out of an old Amer. Rifleman article from the 70's--"Duplicating Service Loads" or something like that.

Don't forget that the c-34 is a magnum equivalent primer! I found that 42.0 grns of 4895 to be a bit much in the M1A's. My load with the c-34 and a 168 Seirra is 39.5 to 40.5 grns on imr 4895.
Work up slowly. No need to beat up a fine gun like the m1a. Gratuitous picture time... 100 yards, 50 shots, M1A supermatch off the bench with the load listed above

Wild--FYI Speer 13 has a bunch of .308 loads "starred" as being tested for the M1A.
Peter--WOW! 50 rounds? You have my respect.

I almost always shoot 50 shot groups. Just a habit from my statistics training and sampling theory.
Same gun, off the bench, same load as above 50 shots per target. National Match, off the bench (open sights also) 50 shots per target and the same load. All shooting was done at 100 yards.

I went to the range and met Peter one day. He just puts those 20 round mags in and shoots away. With no time for the barrel to cool. I was impressed.
Here is a quick pic of my M1A loaded that I took that day to shoot. The group is with peep sights. I load 40.0 grs of IMR4895 with 168 Sierra MKHPs Quote:

Impact,
Thanks! You shoot very well in my opinion. When I get some more ammo made up we should do it again!
