Morning Trapper J.
Can't say which is best , but can say I had a 10" bull that would shoot dime size groups at 25 yards. That had a 2X scope on it at the time. I killed a few squirrels and a groundhawg with it. I loaded it with either 40 or 45 grain Sierra spitzers over IMR 4227 , I think , its been a few years ago. The hawg was only 30 yards or so away...instant kill, through upper ribs into the opposite neck area. The 10" was nice to carry......and for the distances I was shooting, it was good for me. Enough of that , I believe we're neighbors
