We shoot in high, dripping wet humidity at times as well, where the pan is filled with water by the time you bring the gun off your shoulder - yet no one here HAS to wipe - not my brother, our friends, my wife nor my daughter. They all use pure lead balls .005" under bore size and .022" to .023" patches. That solves many if not all problems. The bore remains exactly the same, shot to shot - without having to pack cleaning cloth, patches or cleaning solvents, water, or whatever. It is wiped as you load the next shot due to the compression the ball and patch is making in the bottom of EVERY groove. I've rifles with wipe grooves, narrow lands, grooves just a bit wider than the grooves, equal grooves and lands and narrow grooves and wide lands- I shoot the same combinations in all of them and they all give me 1" or better at 50 yards rest shooting and every one of them loads the same with the 60th shot as the first.
When someone says their gun crusts up and needs wiping or the humidiy is too high and needs wiping, I see both as excuses for not shooting a decent ball and patch combination. If the patch is too thin, the fouling will build up, shot to shot. In high humidity, that ruens to mud - in low humidity, that fouling crusts up - both are merely excuses for what I see as a poor combination.
We also shoot in humidity down to 6% - where lots of folks out West say they have to wipe because it's so dry, they can't load due to the dry crusty fouling. That's just an excuse for shooting a thin combination or not enough lube - usually it's the combination. Merely licking a dry patch doe4s not constitute a spit lubed patch.
I've heard most all of the excuses, over and over again - getting "vomitus" from it - the answer amounts to this - shoot a decent ball and patch combination with a decent lube, spit or whatever as long as it's wet and there are no fouling NOR accuracy problems - ever - no matter what the humidty happens to be. Shoot that combination with a wide variety of loads, from as starting level load to a maximum-type load and you will find a load that will shoot 1" or better at 50 yards if you have a decent barrel - WITHOUT having to wipe. Even my dang TC did an inch at 50 yards in 1973. Most of you are shooting custom barrels and have NO Excuse for having to wipe nor shoot an inch or better at 50yards. If Dutch Shultz's methods teach anything, it's to experiment - do it and stop thinking up excuses.
