It’s ok. I didn’t put much faith into it because it’s a temporary stand-in until my other barrel gets here. It’s fair and decent. I did a functional break-in of 30 rounds then went into a 60-round grouping with 77smk otm. First 7 shots grouped 1.3” which is not bad considering the barrel isn’t even done settling in then for the remaining 53 shots the POI shifted 2” low left -_-
Total grouping with heat/shooter induced fliers 4.75” and a mean group of 2.75” excluding the early shift. That may have just been the settling point but I’ll find out next time. I will say that with similar round count and same test this performed better than a hodge of same length for all 60 rounds. Yea I said it.
