Have a T/C Contender with Fox Ridge short match chamber, 16" twist and it does OK
Uses a Millett SP-1 red dot and it went to the range one day after a thorough bore clean to verify zero. 25 yards shot in numerical order.
On a more serious note:
The gun has killed more than 100 hogs and only one required a second shot. Most shots are in the 15-25 yard range. Record was 38 yards, measured.
With the CB shorts it is sufficiently quiet that I had occasion to shoot 5 one day without taking a step. Mom and Dad in the 200# range, kids running about 40#.
It does not distinguish between CCI CB rounds or CCI short target ammo. Same performance.
Used to have a Rem 572 (S,L,LR) that was quite accurate with CB shorts as well. Expect that is not likely the norm, but it did well.
