I seem to have a 6mm BR barrel with no throat.

Am hitting the rifling right about 2.33 inches. So was thinking about getting a PTG Hand Throater and increasing the throat.

Now I have never throated a barrel, and do not have expert gunsmithing experience or tools.

I can switch a barrel on a Savage, or mount a scope or switch the stock. That is about it... advisable or am I just going to ruin a barrel?
