Rich: be sure, when you lube your patches, that the lube completely saturates the cloth right through. I use pre-cut patches, saturate them with fat, and start the balls into the block. Then I wipe over the bottom of the patched ball with a gob of fat, filling the recess between the wood and the cloth. this gives an extra bit of lube which really seems to help with loading in cold weather. I have about six cans of Lube 103 too, that seems to work well for me, for this purpose.
