Piting
#47061 - 20/01/06 02:42 AM

Guys I would like to ask everyone's opinion on barrel pitting. How serious is this really. I have heard so many comments over the years on how it is a death knell and the barrel is shot. In my experience is that in the case of minor pitting that it results in little if any problems overall. What are your thoughts.

Depends on which side of the barrel it is and how bad it is.

Is it on the inside or outside?

Inside and slight piting is my question. I'm talking hunting rifles not high velocity barrel burners.

Every gun is deifferent.

BP guns seem to fill up the pitting with Powder Residue.

Pitting is something none of us want to have in our rifle bores, but is not a problem at all for a hunting rifle. The smoother the bore, the less it picks up fouling with repeated shots...powder, copper, and/or lead. The rougher the bore, the longer it takes to clean the fowling. How much do you shoot in the field? At what point does the rifle begin to lose accuracy? I have a 450 BPE that has a couple of craters, not pits. The load I've developed uses shot buffer over a normal charge of IMR 4198 and a 360gr hard cast bullet. Velocity is 1900fps chronographed. This load shoots consistent 3 MOA groups...plenty fine for my hunting needs. It's my thought that the buffer protects the bullet and "scrubs" the bore with each shot. My rifle cleans easily. I've had similar success with nasty looking bores in old Winchester lever actions.
