Did your barrel maker give you a “break in” method?? The carbon6 tube I bought said no break in, but don’t be afraid to foul the bore with a shot or two, and then start taking your information after that.
Even with my factory Win70, cold clean bore shooting has been, for lack of a better pun, hit or miss. I got lucky with deer season last year and waffled one 150 yards away RIGHT where I aimed. But then again, Minute of Deer is a very forgiving window of opportunity.

But at the range, when I cook off the first round just to foul the bore, I get consistent ragged hole patterns at 100 yards, three leaf clover things. After three shots, gets a bit toasty and gets fliers.
Stag, would you consider fouling the bore the week or day before hunting season and just leaving it fouled overnight and carrying it afield that way??
For this Mauser I am in process of putting together, I am hoping for long range accuracy, and if I have to foul it before I get anything done, so be it.
Some also suggest “cutting the burrs” out of whatever may have raised up from cutting the rifling. Thoughts??
