2800 fps in a 20" ar-- chrono'd
loaded with standard rcbs dies and no crimp this will do 1.5" at 100 yards with the factory peep for 5 shots. In a bolt it would probably be 1/2 moa as I wasn't even bagged up but had my 30 round mag rammed into the hard rubber surface on the local bench.
I'm not sure of the velocity I'm getting, I've never chronographed them. I shoot a White Oak as well, mine has a 1-7" Krieger on it. This is a standard load for several High Master shooters I know and for myself. It has shot extremely well for me out of four rifles. I'd guess 2,600 fps though for velocity.
