I have a Contender carbine barrel in 17 Remington by Bullberry. I like it but primer flow into firing pin hole is a problem. Using Rem 7 1/2 and full recommended load data the primer flow almost locks the action up, dropping down to minimum load still has flow but not too hard to open. Hate to get rid of it but am considering trading for either a Fireball or Hornet. My question is for those that have had both, does the fireball primers flow like the Remington? I was going to bush the pin hole but it is so hard I cannot drill it out and tap it for a bushing. I know there are other ways to do it but not sure it’s worth the trouble.
