Just completed a deep cleaning of chamber and bore in my father’s 6GT... I understand the barrel now needs to be “fouled in”...in the meantime, should I expect erratic groups, erratic velocity, or both? Thanks
This has been hashed out many times. You have 2 groups of people. People that hunt/shoot clean barrels and others that hunt/shoot with fouled barrels.
IME... factory barrels almost always need to be fouled to group well. Even many custom barrels need this as well. There are a few that are fairly insensitive to being clean or fouled.
You'll need to shoot the gun to determine how it likes to perform.
Most of my guns take 6-12 shots before they bughole again after a deep clean.
Has anyone experienced this to be less of an issue with copper bullets? Its bee my exp and could be shear coincidence he copper bullets cold bores seem to not be affected? I am in he fouling group and still rather use lead
I was just planning on shooting a couple of groups of five rounds over a chronograph this morning...gonna shoot to at least 300, maybe as far as 500....trying to wrap up load development on this gun and just didn’t know if my results would be reliable...
As luck would have it, just got my 6x47 Shehane back from the smith. Had the action re-bedded. Here's exacy what you're talking about.
5 shot group. First one out, next four cut a ragged hole with 105VLDs.
4 shot group measured .267
Factory Sako 6ppc I once had - should never have sold it - would make about 100 rounds before groups started opening up. After a dose of Sweet's, about 2 shots was all that was needed to be back "right".
