I used two diffrent load's. both with fireformed brass. first was, 120 gr. nos. bt. second was speer 130 spfb.
The barrel play is left to right, not up or down.
It's an older frame, the one that you use a screw driver to change between rim, and centerfire.
I have other carbine barrels, that work fine on this frame.
The lug is split, and the barrel is stainless, If it matters.
Thank you very much for taking time!!
Bob.
