.280 154 SST @ 2945 fps
It was hot on Saturday, but the velocity in Feb. was only about 10 - 15 fps slower. This is out of a 22" barrel. I would stick with the standard .280 and see what you can do. As OT3 mentioned, load data for the .280 is very anemic. I'm roughly five grains over book max and am not getting any pressure signs. The brass I believe has been fired six times now and is doing fine. Someone ran QuickLoad on this for me and my pressures should be right around what is max for the .270. There is no reason a .280 in a modern bolt action can't be run at the same pressure as a .270.
P.S. The targets don't typically look like that with this rifle, I wish they did. Bedding or a new stock might get me close.
Very nice shooting Trevor! That 280 looks really good! Scotty
