I have a Pierce action Eliseo tube gun in 6br with Jewell benchrest trigger. I have about 1000 rounds through in without previous problems.
Recently I broke the trigger. I didn't know what caused this failure. Dies have been the same, load is on the hot side. Primer, brass and bullet are the same, CCI 450's, lapua brass and 105 Lapua's. I recently changed to IMR 8208 XBR powder but have successfully shot about 300 rounds with the IMR load. Primer on round when trigger broke was not pierced, no brass flow, easy extraction.
I thought this was just some anomaly since I had not had problems with the same variables. I should add I had previously tried wolf SRM primers and could not get them to fire in the Eliseo, I think the firing pin spring is weaker than normal. I've had variable success with the wolf primers, some of my rifles work with them, some do not. I think it is related to the strength of the firing pin spring strike.
Dropped in a new Jewell benchrest trigger, it broke on the first shot. Primer was not pierced, no brass flow, easy extraction.
Any ideas or a fix?
As an aside if you haven't tried IMR 8208 XBR in your 6 BR you should. It's only up to 40 degrees here so I don't have any experience with it a warmer temperatures but so far it's impressive.
