30/30AckleyIMproved....been there, done did that...and it works GREAT! [H&R, not a Ruger #].
I'd do it all over again, too. I've owned a LOT of different rifles/cartridges, and the PLAIN JAIN OLD THUTTY THUTTY, is STILL a great round. If you can't get it done with an accurate 30/30 and good quality bullets,.....well...nuff said.
