Brad,

In my rifle (a Featherweight Classic) 3-shot groups with 150 Partitions are averaging .8 with 60.5 grains, and a little over 3000 fps from the 22" barrel. The primer is the F210 but the brass is Winchester from maybe 4-5 years ago, which tends to run thinner (but harder) than Federal cases. So far haven't run into stiff bolt lift at velocities up to 3100 fps. How much do your Federal cases weigh?
