Lots of Speer 270 gr Sp bullets available. James 1 it is a 9.3 x 57, not the 9 x 57.
So far it looks like 44gr of 335 powder with the Speer 270 gr bullet might work, Recoil is a bit stiff, but primers looks fine, no pocket enlargement, I'll chronograph that load and if it comes in at around 2100 fps that will do fine. Thanks for the tips guys,
Mike
