I am gearing up to hunt black bear this September, and am planning on taking the 54 caliber TC Renegade as my main rifle. I've mainly stuck to water lubes for the target range, and many things work in the winter deer hunting season. I have never hunted in hot weather like this before. Average high temps will be in the 70's, and 90 is not unheard of. I am concerned with leaving it loaded for a month and having the lube contaminate the powder. I am going with a round ball, and pillow ticking patch for this. I've got a couple ideas. The first is to go with something like real mink oil, which cannot separate like beeswax/oil. The other is using an over powder wad. I've never bothered to try a wad with a PRB, but it seems like it may provide a decent barrier for the powder. Another question I've had, is has anyone tried an unlubed patch? I'm only going to take one shot, I don't care about the fouling.
