OK this seems like a good thread to get back into the converstion again.....

I have 3 Renegades that I use for shooting PRB's, all three of these rifles are very simular in the fact that they are 1/48 twist Renegade barrels, one is Douglas, one is a Shilen, and the last is a TC made barrel.

The load remains the same in all three rifles....
60 or 70 grains of T7-2f powder
A Ox-Yoke Wonder Lube Wad
Either a .015 cotton Wonder Lube patch or a .018 Pillow Ticking Wonder Lube Patch,
A .490 Round Ball

Al three rifles shoot very accurately with this load....



The problem.... The recovered patches...

These patches are/were purchased from TOW, they come in a heavy aluminum zip lock package that is complety sealed from the air. When you open the package the Wonder Lube is very moist. I do supplement the lube on the patch by adding some of Cayugad's Moose Milk - so I believe the patches are well lubed and equally lubed.

This is an example of recovered cotton patches and wads. The upside of the wad is the side I believe was sitting on the powder. And you can see the patch is shown with the ball side down.



In all three barrels, the 0.015 patch loads with what I feel is just the right amount of pressure all the way down the barrel smoothly and with equal pressuer.

I can load a 0.018 patch with more pressure but it feels tight...

When I go to recover patches to check their condition... that is when the problem become apparent.



Cotton patches on top - Pillow Ticking on the bottom - equally treated patches...

It comes down to the fact that cotton patches work very well but the more common and more popular Pillow Ticking patches shred something fierce. The do not appear to be burnt...

I have looked for answers to this problem before but still have not in my mind got it figured out.

Just so you know I really believe that all three bores are glass smooth and free of any pitting.

I have shot, or did shoot a few cans of GOEX-3f from these guns when I first tried shooting PRB's and I do not remember if the same problem existed with GOEX or not. I just really prefer shooting T7 - cleaner and I do not have to shoot as much per load so it is a bit cheaper...

And remember the guns all shoot very accurately - well accurately for me...

Thoughts?
