Black Mag3 vs. APP
I shot black mag3 and APP side by side today from my Omega. I used CCI 209 primers for both.
Today with the bullets I used (405 powerbelts and 444 powerbelts), BM3 was the more accurate powder. Different guns and different bullets would likely have different results on accuracy.
I give BM3 a slight edge on less residue between shots. Both were much less than 777. No crud ring with either.
BM3 had noticably less smoke from the end of the barrel.
I give BM3 the slight edge in having less felt recoil.
Did not have a chronograph.
BM3had noticably smaller grains even though I was using fff APP. I did notice that BM3 seemed to settle more, possibly due to the smaller grain? Might make if harder to have shot to shot accuracy based on volume alone.
I am going to continue trying both powders with different bullets. I am most interested in Black mag3, so hopefully I can find a good accurate bullet. Today, with 100 gr. BM3 and 405gr powerbelts,I was getting bullets holes touching at 25 yards, and around 2" groups at 50 yards. Should be good enough for the distances I shoot (max 100 yards) but will have to shoot farther next time.
