Alright, got one more set of 25 using H4350, all loaded to 45.0 grains with the Berger 175 Elites (best shooting, and best ES & SD load I got with H4350), and I'm going on a hunch, but going to swap the suppressor for my TBAC Magnus-S... The barrel threads on the
@CarbonSix barrel are NOT 100% straight, and are slightly crooked...One of the main reasons why it's going to be going back to them most likely... However, after checking with my alignment rod, 2 of my proven truly straight 9" cans (OCL Hydro-L & TBAC Magnus) both lean just a bit too close to the side for my liking. I tried multiple cans, and multiple different mounts with the same results, so SOMETHING isn't 100% straight on the threads, whether it's the shoulder or the threads themselves.
I think this might be affecting bullet flight (I.E. my groups)... When I put the shorter 7" Magnus-S on there, the alignment rod is much more centered in the bore.
So, I will be testing a group both with and without the Magnus-S this upcoming weekend. If it gets good groups without the can, then we know there's a muzzle thread problem and it's going back to CarbonSix. If it still shoots like shit with AND without the suppressor, then we know we have an internal barrel problem, and it's going to go back to CarbonSix. So, most likely, either way, this barrel is going to be getting sent back to them.
IF it shoots noticeably better with or without the suppressors, then I will try another run of StaBall 6.5 to see how it does with that, as well.
But, at this point, I'm certainly not holding my breath, or expecting a whole lot of improvement. However, I could be proven completely wrong...It's happened before.
