I recently got a T/C Bone Collector Triumph. Went to the range to sight in yesterday, had an issue with my primer not allowing the breech to fully close. I was using the 777 Winchester primers. Did a quick Google search and found that some primers have too thick of a shoulder to allow the T/C to lock closed. Luckily I had some of my old ones which worked, but I had to shut the breech several times to seat the primer before it would lock shut and then I could shoot. Has anybody else had this issue and if so, what primers work..?? Shot very well otherwise, nice gun.
Work is for people who don't hunt!!
