Well, it's settled in. I also put that upper on a different lower with a much better trigger. I think it'll do
That's 5 shots of the same lot of IMI Razor Core 77gr (aka mk 262 mod 1 clone) Also had the heavy barreled precision upper that normally lives on that lower, and couldn't match it with a barrel that cost 3x what this one did
That’s awesome shooting! Glad the barrel worked out.
Thank you both. I'm guessing the bore was rough and it took those 25-30 rounds or so plus a couple of cleanings to smooth it out. Still collecting SOME copper, but nowhere near the amount I was
