Short Barreled 280AI

Petersen brass annealed after every firing.
60.5gr of 7828 ssc.

I can't get GRT to make it make sense, but I'm glad you're getting that kind of juice!

I put my first rounds through a 22" supressed 280AI this past weekend. 20 rds of Barnes 152gr LRX factory averaged 2930 fps. Happy with that... we'll see if it speeds up any more.

That's hawt. I'm having grandpas old .270 rebarreled to a 280ai, and that bullet is one that I have been looking at!
