Best powders for M1A SOCOM

[David Sinko]

I already sold this rifle. I noticed that all my resized brass would fit in the chamber with room to spare, but some of them were very tight once the bullets were seated. Either the chamber was a bit tight or the necks were getting thick. I did try most of the powders that were suggested here and nothing helped. I suspect my problems were brass related and I just can't tolerate that.

As an aside, I took my brass that had been abused in the M1A and converted it to .300 Savage for my Model 99. I threw out those with loose primer pockets and the rest functioned with perfect reliability.
