Hello, Recently, I sent a brand new Tanfo Stock II over to Patriot Defense for their patented tuneup and barrel reaming. They also installed the extended firing pin, titan hammer, bolo, one piece sear, and Xtreme trigger. Out of the box the trigger was PHENOMENAL, both in DA and SA. Unfortunately, the first range trip was plagued with failure to feeds, and a weird "ca chunk" whenever the slide cycled. After perusing the forums here, it seemed I needed to chamfer off the breechface edge and polish the breechface. I got in contact with PD and they confirmed it was probably the breechface edge issue and gave the go ahead to chamfer the edge while also telling me Tanfo's need a 1000 rounds to break in. They even stated there were no issues when it was test fired at their facility? I chamfered off the edge and breechface little by little like everyone suggested until the failure to feed issue stopped, but the "ca chunk" continued. Thinking this issue stemmed from the wolff 8lb standard recoil spring, I tossed in a wollf 10lb standard spring to no avail and a factory 14lb spring which yielded the same result. After noticing weak ejection with softer ammo and sometimes rounds getting stuck with the slide out of battery, I bought a new extractor with the (9) stamp and an XP extractor spring to cross this off the list (the original had a bunch of machining marks and no (9) stamp). Next range trip, the "ca chunk" continues and within 100 rounds two were somehow stuck in the chamber while the slide was 1/8"- 1/4" out of battery. I had to take the gun apart to get the rounds out since the slide was stuck. This makes me think there is something wrong with the barrel after it was reamed, maybe. The mags I am using are brand new K9s. The issue happens with all mags (12) and all ammo. Everyone that has seen it in slow mo and shot it agrees it's not cycling right. Any thoughts??
I have a stag 3t,any type of factory ammo runs fine. my brother recently gave me single stage lee press with rcbs small length dies. I lube all the cases and the neck I set the die all the way down to the shell holder an then turn it back an 1/8'. all the rounds do not seat do to the shoulder not being bumped back enough. ive tried trimming the brass, backing out and backing out the decapper rod. I then reloaded rounds on a friends Dillon 650 all passed chamber check, at the match today I had 8 FTF not even a mark on the primer an had to slam the buttstock while pulling the charging handle to eject the rounds. another guy told me my chamber might be to tight and told me about having a gunsmith ream out the chamber. does any one have any ideas on the matter?
