Back bore to remove pits

[B. Dudley]

Pitting always looks worse than it is when you are looking down the bore. Because you are looking across the pit. Not at it dorectly the Surface.

If used properly, a manson gauge will provide you with accurate measurements for wall thickness. But the large ball end on it does not allow you to measure how deep the pitting actually is. A hosford gauge is much better for this.

The measurements you have listed on the barrels look to be perfectly normal for most barrel sets. I would not call the barrels junk too quickly. At least from a shooter standpoint.

I would not recommend any backboring. You would be throwing money at something that is just going to compromise the integrity of the barrels. Yes, pitting looks bad, bit it usually does not effect the shootabiltiy of a set of barrels.
