AA 2520 Powder
Posted: Tue Jul 27, 2021 9:18 pm
After a 40 year hiatus from reloading, in 1999 I got back into it because I had inherited my grandfather's Savage model 99 rifle chambered in .303 Savage, and I could not find any factory ammo for it. I bought Lee reloading equipment and Lee's book on reloading which listed AA 2520 for reloading .303 Savage and .30-06. Since then I have used that powder for my five 30-06 rifles to include a '03 Springfield and an M1 Garand. When I am "on my game" at 100 yards, I can still shoot reasonably good groups with with both rifles.
Last week I reloaded 25 rounds for my .30-40 model 1899 Krag Carbine using 28 grs of AA 2520 behind Hornady 220 gr Interlock RN bullets. Yesterday's range results are encouraging. At 75 yards I shot 4, 5 round groups measuring 3", 4.5", 6", and 7". There was a flyer in 3 of the 4 groups which I overlooked when measuring the groups. Recoil was mild. extraction was easy, and primers were still a bit recessed after firing. The temperature was 88 degrees with no wind.
I am out of 220 grain bullets, so for my next time at the range, I will move down to 180 gr Hornady RN Interlock bullets, using 25 grs of AA 2520. If results are OK,
I will increase the powder by half a grain until extraction becomes stiff and/or primers show signs of bulging. AA 2520 is double base, spherical powder that is easy to work with, and meters very well.
