Hi All,
Ive recently had an issue with one of my guns which I believe was related to the guns barrel and/or chamber being dirty. I want to run the scenario by you all and get your thoughts. Ive recently changed my cleaning protocol from once every 10-20 shots fired to once every 150-250 shots fired. This was based on listening to Forms posts here on Rokslide, Shoot 2 Hunt podcasts (both espousers of the “never clean” method,) along with Hornady and GunWerks podcasts (both who suggest cleaning periodically due to their observations that not cleaning can lead to pressure issues.)
My situation in brief:
I shot my 6.5 Creedmore with hand loaded 130 grain Lehigh Defense Controlled Chaos bullets two weeks ago at the range and had 4 blown primers out of 12 shots fired.
Shells were loaded by me at the point of very mild pressure signs. 2800 fps. Ive shot over 100 rounds of this same ammo to date with no issues. Then suddenly on this one day I had stiff bolt lift on all shells and blown primers
Came home, cleaned barrel with boretech eliminator, nothing special, just their recommended procedure. Noted that the chamber and throat seemed very dirty, including chunks of blown primer gunk.
Then yesterday went back to the range and fired 10 shots with zero issues.
My best guess is the dirty gun caused pressures to spike. Seems to fall in line with Hornady and Gunwerks podcast “data.”
But Im a newb and Id expect that Form and Ryan would say that it wasnt a dirty gun issue. So im a bit confounded and curious as to what else it could be and what im missing.
Now: the details:
Brass is all first load Lapua and I did not size the brass. Just chamfered, deburred and loaded. Federal large match rifle primers.
Bullets are seated longer than SAMMI but not into the lands as I had to load to fit the magazine. OAL of 2.32” my measurement hd the lands at 2.334
42 grains of H4350, hand thrown and powder measured for every shell and Im confident that all shells were loaded within 2/10s of a grain. I did buy a second pound of H4350 and noticed some variation in velocity with the second batch of powder. Avg of 2798 for first batch of powder and 2759 for second batch. Loaded 200 total shells. Let me be clear here: Im new to reloading so maybe I f’ed something up. But dont know whay that would be.
Action is defiance Rukus, barrel is 22” proof carbon. Shooting suppressed. Do suppressors increase the back pressure and therefore increase the risk of primers blowing out?
And can I reload those pieces of brass that blew primers or are they toast?
Thoughts?
Thanks
