Best load is 41 grains with BR4 primers 3414 fps 8.6 SD .474 group. Just bought 100 pieces of Alpha Munitions 22 Creedmoor brass and I'm going to work with it. For bullet seating I took a Forster 22-250 Ultra Micrometer die and used the same Chamber reamer on the die sleeve, had to take some off the face of the sleeve since the 22 Creedmoor is shorter than the 22-250 to the start of the shoulder. The Alpha brass weighed lighter than the Lapua brass and using the same load as above it was 46 fps slower. When I went to 41.5 grains it was 3415 but had an SD of 15.8 and group size was .412. The rifle and the die work was done by a friend of mine. My build is Kelblys Atlas Tactical action, Bartlien 7.5 heavy Palma barrel, Trigger Tech Special trigger and Greyboe Ridgeback stock with DBM. Vortex 6-24x50 PST on top. My groups have some verticle stringing so I'm going to start playing with seating depth.
Excellent write-up Jerry. Thank you. Hope to read more as you progress!
