Good question.

I just picked up some 36gr this weekend to try with .223 1:9 DPMS panther bull 20 and a .22-250.

Reloader's Journal has old article for this bullet and cartridges, but they used 1:8 Sisk rifle for the .223.

I plan on using AA 2230 for the .223 and R15 for the .22-250.

Article used 39gr of R15 for the .22-250 and got something like 4400fps.

I think the .223 in the article was 3650fps+. I plan on starting well below max for AA 2230 powder loads which max out over 3800fps in Accurate's load data.

These bullets are quite a bit longer than 40gr Sierra HP. They are also quite hollow.
