I think all current CVA 45s are 1-28 not 1-25. The 45-300gr PB really isnt that bad, just dont push it. The rest suck IMO. Shoot it slow like any other conical. Those are the only three i remember shooting. It shot a 200gr SST and 100gr BH209 just fine so i didn't play with conicals too much and the bore was so large that sabotless would have been a PITA to shoot the bullets i wanted to try. Then i did try a few modded bullets and when the powder charge got high enough to stabilize them, the primers started to flow so i gave up on sabotless for awhile and sold it.

I will be playing with sabotless again before the season starts and my new bullets arrive.
