Semisane, as mentioned in my thread, I use the T7 Primers in My SS/Camo ACCURA and they fit loose in the Breechplug wich causes me blowback, would a small pice of teflon tape on the primer work to tighten the fit of the primer in the breechplug?
There is a good fit between the primer and firing pin so no need to adjust or back out the breechplug, or in my case I can even back out the firing pin screw on my ACCURA. In My SS/Bk ACCURA I use Win W209 Primers, they fit tight in the breechplug, so that combo is O.K. I may just change to Win 209 Primers in my SS/Camo ACCURA after the Season, but I have about 7 or 8 packages of the T7 Primers so that would be a waste of about 800 primers, plus they work good as there not too hot and they are a tad longer for a good fit, but they are thin in the BP.
As Sabotloader mentioned the (slack) or (looseness) by backing out the BP may cause problems down the road with the excessive pressure against a slightly loose BP might happen, he may be right. But the BP's do have a-lot of threads on them and if you do just loosen the BP out just a 1/4 turn, it should'nt matter as the BP is still tight, especially if you use Teflon Tape on it. So who know's what will happen in the long run with a 1/4 turn backed out BP for a better fit for the primer. Let us know if you experience any problems with this down the road.
For now Im gonna try some Teflon Tape on My T7 Primer's fit in the BP and see if that solves the problem of Blowback.
