Thanks, my post was not specific enough, I'm shooting short range, 100-150yds, thought the 1x9 was best twist for that, 1x7 need to shoot heavy rounds? 69gr plus? Anyway, looked at the barrel you mentioned, interesting. I'm installing a Jewell trigger now, first time, going OK, should test fire soon, then I'm ready to find the barrel.
The 1x7 twist seems to be a hot topic but I'm not a reloader of .223 at this time.
