Inconsistant groups advise

[jonny315]

So after a cleaning, I re-broke in the barrel as per mcgowens advise. Still no change, brought it to a local gunsmith to check it over, he thought the bedding wasn’t an issue and said I might want to send the barrel back. I may just accept the fact I have an inch and a half gun.

Looking at the barrel pictures again, it was noted that it’s fluted. Assuming that they were added after rifling, I’m wondering if the secondary machining has adversely effected the barrel’s internal dimensions (straightness/diameter)? Returning it to the barrel manufacturer may indeed be revealing...

This is a factory barrel. That may be as good as it gets with the particular load you are using. Or at all.

This is an aftermarket Mcgowen precision barrel, i sent in the original model 70 and they built the barrel, chambered fluted and installed it for me.
