I've used my Huntsman 24" and 209s for several years with success, great accuracy, reliability, etc. but more blow back than I like. So, I bought one of the 25 acp breechplugs and tested her out. Used small rifle primers, as recommended and 80gr 777. Of 12 attempts, I had 4 misfires where the primer detonated but the 777 did not. This is not good. Any suggestions for correcting this? Otherwise it is back to 209s.
best, nrb
