I'm a bit suspicious of the patching...On the target it says T/C patches, but the first set look like some cotton material you cut in squares...

The reason I bring this up is that the groups in my .54 opened up one year and it ended up being old prelubed store bought patching...I now buy pillow ticking from WalMart and make my own lube...I even went through adding hornets nesting or a wad between powder and ball...
