I have a terrible time with the ' crud ring ' problem in my .45 cal disc. Does any one use the percussion cap adapter in a disc rifle .Do you have good performance with it ( accacury , dependability in all weather conditions less crud ring etc. ) I have seen the pistol primer adapter that is being made for other models and it is noted to inprove accacury and help with the crud ring problem. I have read all the threads about the 209 primer being too hot . I have not tried the adapter in my gun yet . One came with my rifle and they can be purchased from knight thanks!
