Here are some I put together using H4895 at Hodgdons max listed load of 24.5 Grains with CCI 450 primers at 2.240" in Federal brass.

They average 2948 f.p.s. out of my 20" Ar15 performance 7.7" Twist barrel.

The wind has been blowing like crazy the last couple days so I have not shot them at targets yet.

They were faster and easier on brass than the loads I worked up using CFE223.

I was thinking real hard about the valkyrie in a bolt gun and then I found a 223AI reamer. Built the 223AI on a 7 tw and it shoots 80gr bergers with varget very well.
