I just did a bit of work on my Bulldog and here is the 10 shot sting using 81.02 JSB .35 cal. Chronograph was measuring at the muzzel. I opened up the transfer port and valve to .281. I tightened the Hammer Spring 2.5 turns from stock. Everything else is stock. I've never shot big bores and I'm curious as to what a decent shot string looks like. This string would be unacceptable in my .22-.25 guns, but this gun may be different. Can anyone with more experience with big bores give me advice on how to better this tune? Groups are acceptable at .75" at 50 yards.
