Tight group vs time between shots ?

Yeah, four skinny Minis. But, mostly three-shot groups when on the bench checking sight-in. Usually around 1.5 MOA with a Weaver K4.

Your comment ....this gun kills cheap scopes....got me thinking.

Maybe you have air space behind the recoil lug. A simple test would be to add shims, layers of masking tape would work, until the action won't fit into the stock anymore. If it were my gun, one layer of tape would be too much room.

I have never considered that possibility , after we shoot it this week I will try your idea & Ontarget had an idea to try also.
I know it seems like a lot to do with nothing over an old 1903 rifle but I enjoy a challenge in accuracy or gun repair.
Especially since my Dad gave it to me.\ A WW2 air force communications vet & he just turned 93 years old./
Thanks
