Took my 3 barrel combo out today for a bit. Shot at 100 yards: .357 with 4x scope grouped a groundhog round (110hp) at 1.5", deer load 158sjsp at .8" (.25" verticle spread), and .223 just over 1" 50gr vmax. Swithched barrels around and poi changed pess than 1/2". I'm happy. I only shot the 30-30 at 25 yards and didn't really test it that well, but maybe when I get more time and a peep. Just thought I'd share.
ETA: I was using a bipod w/o rear bag. It got switched around every barrel swap too.
