Went out to do some shooting today with both Omega’s and noticed something interesting. The STS primers (Blackhorn 209, 80 grains) in one have a lot of soot on them, this Omega I’m trying to figure out an accuracy issue as well. Will this blowback affect accuracy at all? From research the breech plug may be flame cut? Looking for options. Interesting that the other Omega using the exact same setup the primers are perfectly clean. Thoughts?
