There has been a lot of discussion here concerning gain twist barrels. I had Bobby Hoyt bore and rifle an original Ohio rifle to .40 with 1/60 to 1/40 twist. It shot very well, heavy charges, light charges, I could shoot em all. Probably the most accurate rifle I have ever owned. Lots of squirrels and lots of X's!!! That was 35 years ago when I could shoot and when I could see! If you believe a gain twist will shoot better then it probably will shoot better, Your confidence in the barrel will make it shoot better!!!! (IMHO)....LK
