I just saw a thread on here about CVA not wanting people to shoot conicals over 400 gr. So take that for what its worth. I have a CVA Accura V2 and I love it. It shoots plenty accurate enough for me and I've killed everything I shot at with it using 295 gr Barnes bullets. I've also shot 300 gr Hornady XTPs (.429") using Harvester green CR sabots.
I don't have a Knight anymore. Not because it wasn't accurate. But because I disliked the firing/safety system.
