ORIGINAL: BS
I shoot tight patch and ball combos, and my barrels just don't shoot it well. As stated, a looser combo may.
Your loading may be needlessly tight due to the bore-wall stickiness associated with your lube.
How long have you known Stumpy? When you mentioned finding Permatex faults with more than one barrel, a red flag was raised by me.
I'm done here -- only because I suspect a lie or two. Saying you had inaccuracies in all your barrels said enough for me to just walk-away from here.
