Hello. I have a Benelli M2 with a 21" barrel and a Nordic +5 extension. I took it to the range last week to run drills and practice with Federal 7.5 low base birdshot. I had multiple failures where the action cycled and it loaded the next round, however the bolt did not move far enough back to cock the gun. The gun was clean and lubed properly.
So, I cleaned it again. I really went after cleaning the barrel chamber thoroughly. And, I flushed out the recoil spring tube with gun scrubber. I lubed the trigger assembly and bolt in the right areas. Nothing looks broken. The gun has about 500 rounds through it. I have not experienced this problem before.
I am taking it to the range Saturday.
My test:
1. 25 rounds of F127 9 pellet 00 buckshot.
2. 25 rounds of Federal low base 7.5 birdshot
My Question - if the guns runs 100% with buckshot, but fails occasionally with the lower powered birdshot, would you trust it for home defense?
I hate to give up on it. But, I don't like unreliable guns. What do you think?
P.S. I shoot the same Federal 7.5 birdshot all the time at skeet, trap, and clays in my other 28" hunting M2s. I have never had this happen once in my other M2s.
