More testing today - different powder (SW Match Rifle) but same 123 ELD-M bullets. I did two 5-round group/es tests and lo and behold I got a ringed Starline (new) on one of the cases in the second groups. At that point, I lost trust on this barrel. I'm going to contact Odin Works and see if I can send it to them for evaluation. BTW, when the gas block was off, I measured the gas port at around .076-.080? Hard to get an accurate measurement with my old RCBS caliper. Again - I closed the gas on this barrel and slowly (? turn) opened until I got a lock on last round. I feel like the gas is controlled, and this was with the Monster bolt and H3 buffer. Fun stuff. I think I'm going to order a 16" monster barrel in the mean time...
