Does that lever bite your hand a bit with .35 recoil? I'm slowly working on a No.3 project- had JES rebore a .223 to 9.3x62 and am restocking with No. 1 pattern wood. There's no way I'd want to shoot it with the OEM lever, so I cut, welded, and shaped it to be more friendly for recoil.
As a matter of fact, yes it does at the range. It's a pretty light setup with ballistics nearly equaling my .375 H&H mag 270gr loads, so yes it can be a handful. As I recall, it banged my ring finger pretty good if I shot it loosely off bags.
