Me thinks, twer the thing semi-regulated, where the two barrels print side by each about an inch and a half apart, could be a really fun Rifle. Er .. Shotgun. Er, rifle-shotgun.
I have a partner (who saved my bacon this past weekend) who shoots an H&R Handi Rifle in 45-70 for Plainsman. His load is with Round Ball (454 crimp at equator), some BP and some filler. The thing shoots like a laser. Now, if that Baikal is semi-regulated, with those Round Ball Loads it would be really fun!!!
