I just picked up a new in the box SP10 from the early 90's original bottomland it has a 23" barrel. Anyone shooting a 23" barrel? If so what are your results with your setup?
reading my earlier post , I obviously must have been inhaling too many engine fumes , I don't see where you asked anything about a 26 inch barrel , lol ...
tried many combinations with my 23 inch sp 10 but have come to rest on the kicks choke and federal hw number 7 combination , it routinely puts 200 pellets in a 10 inch circle and the patten is nice and big allowing for error , a fed7 pellet out of a 10 gauge will break a gobblers neck , I've seen stray pellets break a gobblers leg before at 40 , it hits with authority
the federal 10 gauge loads shoot at 1300 fps and has good patters and knockdown , and is real easy to buy at many places , and relatively affordable , stock up if you can
