Though the majority of real-deal Benchrest rifles are glue ins (the exception being Hunter class rifles where the rules prohibit it), I'm in the minority and pillar bed my junk. On the Panda for my 30BR HV class gun, I fitted it with a recoil lug and did a few other tweaks:
These 3 shot groups are with bullets from my new bullet making dies. The 5 shot groups are running about 40% larger on average. Being a bolt-in doesn't appear to be a handicap.
Good shootin' -Al
BSA will be along shortly to ridicule you for not shooting 10 shot groups… Laffin’!!!!!!
I can’t imagine the time, effort, knowledge, and precision it takes to shoot groups like that. Well done.
