Sharps? Variants? BPCR? (Or, "Feeling what might be a developing 'itch'.")

i have a chronic frozen gun shoulder condition that made me experiment with ways to best mitigate hefty recoil of a full house .45-70 PPB cartridge loaded to the rim with compressed black powder (83 grains) under a 523 grain PPB. a kick killer akton butt stock pad is what i use along with a past shoulder pad, and can fire off 60 or more continuous rounds without feeling a thing during or after.

Formal offhand target shooters (i.e. the immigrant German "Schuetzen" shooters) determined by 1900 that their best calibers fell between .28 and .33 - even the venerable .38-55 gave too much recoil to let a man shoot a score without excessive fatigue, unless he was built like Paul Bunyan. 'Course a score for those guys was 100 shots in a day at 200 yards. That game is still played today, but you might find something less demanding.

with consideration of the above ...

deciding on a BPCR/TR gun is one thing, whilst the cartridge choice is entirely another.

the distances within game(s) to be played will have a large influence on the chosen cartridge. at the longer venues, bigger/heavier lead will be better, and that will typically mean added recoil. it is what it is.
