I started out with Powerbelt Aerolites when I first got my Accura V2. I didn’t find them to be very accurate. I switched to Harvester Scorpions and now shoot their 300 grain White Lightning with their sabots. Those with 110 grains by volume of BH209 and I have holes touching at 100 yards. The biggest issue that I had with my CVA was getting blowback into the firing pin housing and that fouled up the firing pin and caused it to stick. I found some rubber o rings that fit into the primer hole and haven’t had issues with it since.
This is my problem. i have the same gun. So you put the o ring in the bottom of the hole and then push the primer in? Ive never really understood that. Ive heard of this solution though. Definitely no issues getting the primer out after the shot lol
