I have a 300 win mag defiance action with proof barrel 1:10 twist and I have been reloading for it a little bit. It has 20" barrel.
I am using
185gr berger bullet's
69.00 grs powder - IMR-4350
I am getting around 2860fps
Sometimes my SDs are great and sometimes they suck but 1/2 moa to 3/4 moa groups.
But anyway do you think 2860fps sounds right? Do you think it's too fast for a 20" barrel?
