I have a CVA Otima Pro. in .45 caliber. I have been shooting 100gr 777 pellets with Power belt 225gr bullets. I have shot 3 deer and have not been impressed with the overall performance. I was thinking of changing to 150grm 777. I have now heard rumor of numerous barrel and or breach pug explosions and or failures. Has anyone here heard of the same? Wanna kill these ads? We can help!
