Winchester cases, Fed 215 primers.
Information, not recommendation - loads were at the top end of the scale powder wise.
Tried RL23 but case did not have enough capacity to get much past 2900 fps with OAL limited by throat in this rifle.

Yeah that matches with what I got with RL22, 2850 - 2890 before hitting pressure signs in WSM
