the only powder i used with this combo was wc872 and 97-99 gr was all i could use,depending on temperature, before the bolt would start to get sticky.don't know the velocity.this was out of a 3 groove, 7 twist barrel.

Fed 215M, 88.0gns Retumbo gave me 3280 out of a 29"tube. 1/9 twist, great accuracy. This is the only powder I have tried so far. I was able to go up to 90.0 but it was a hot load. Reduce the above load to start with, and of course, use at your own risk.
