:) used H4350 at 65.5 grains win brass CCI 200 primer speer 165 grain spitzer boat tail COL of 2.81 no chrono but if I had to guess 3100 fps
shot to separate 3 shot groups off a table at 100yrds .46MOA .47MAO.

I wonder what kind of group these would shoot of a proper shooting rest?

Nice shootin! With groups like that I wouldn't worry to much about velocity. But, if I have to guess I think you may be a little high on your velocity estimate. Hornady lists 67.5gr as 3100fps and Sierra has 67.1 at 3050fps/24 inch barrel.

Steve You may be right.
maybe one day i will know for sure.
my rifle has a 26 inch barrel though.
dont know how much differnts that would make.
