Im not to sure the paper is not abrasive. That is why I have avoided them If you get the barrel conditioned with a good lube leading will not be a problem. how long will a bore last with paper patch bullets? They go a long way with copper jacket. I think paper could be more abrasive than copper. Like everything that rubs at high temp. I try to add castor oil to the lube. could a pp bullet be lubed with castor or is it a problem with blk?
Thanks

This thread makes me wonder about the safety of the "Texas Bore Pigs" that are becoming popular for clearing fouling between shots. Since they are made with either a nylon or bronze brush backed with a series of Scotchbrite washers, it now appears they may not be a good idea. I think I will just continue to use my cotton patches.

Brent,

Well, I don't know enough about the Scotchbrite to know the differences. So I figured that in my ignorance, I might just be safer to stick with what I am familiar with. I am pretty confident my cotton patches are of no danger to the bores of my rifles. But then I have been intrigued by the reports I've heard of those using the Bore Pigs. The Bore Pigs certainly are reported to clear the bore very well. 

Do you think the Bore Pigs are safe? I value your opinion a whole lot more than mine on this issue.

Thanks Brent,

The concept of the Bore Pigs and the reports I had heard and read on them has attracted me to them, but the recent comments on Scotch Bright made me want to ask more questions. But if you have had good experience with them, then that sounds good to me. 

I really appreciate your input, and I apologize for hi-jacking this thread. Didn't mean to do that. Just wanted to learn something.

Good morning, Board;

Before everyone gets all agitated and starts kicking xx about fillers, let me relate an experiment I did with scotchbrite.  It is true that all scotchbrite is not the same, so this applies only to the green grocery store variety.

I chucked a one inch piece of coldrolled round stock in the lathe and "touched" the tool to it to make two rings about 1/2 inches apart.  I did this so I would run the scotchbrite and so I would measure in the same place each time.

After marking and measuring the workpiece, I set the lathe to 1000 rpms and held a new piece of scotchbrite against the workpiece and pressed firmly on it in two places (thumb and forefinger).  I stopped after 15 seconds and measured the workpiece.  No change.  So I did it for 15 more seconds the same way.  No change.  So I did it for 30 more seconds the same way.... well, almost the same way.  I may have quit a second or two early because the friction burned my fingers.

THERE WAS A CHANGE!  The workpiece was (as well as I could measure) somewhere around 0.0001 and 0.0002 LARGER.  I think the larger is a measuring error or else the piece expanded from the heat generated. Two thousand firm applications of the material did not make a significant difference in the dimension of cold rolled steel.

So, now I use green grocery store scotchbrite with no second thoughts.  I like it.

Y'all be good.
