Good info, gents. I think I will try a bit wetter patches, and maybe try something beside Ballistol. I also may try using pillow ticking versus the pre-cut patches I got from TOTW.
Patch thickness is where you get the "cleaning while loading" routine. A wet patch is, well, wet. Slightly damp or dry does not work for this, whether the lube is WWWF+oil, Windex, water, spit,
Mr. Flintlock's lube, Track's Mink Oil, Neetsfoot oil, LHV, Hornady's BP lube/cleaner or whatever. They all pretty much load the same with no wiping - IF, the ball and compressed patch combination at least come VERY close to the bottom of the grooves. In my .69 & .50, I can load continually without wiping, combinations that shoot just fine at close range, that show brown scorch marks on the recovered patches from each groove, yet they still clean the bore just fine while loading (with lighter loads). With a ball only .005" smaller than the grooves and an 8 ounce (.018/.019") denim patch, This type of shooting will occur. These combinations usually do not shoot as well at longer ranges such as 50yards and beyond & tighter combinations are needed.
The "ultimate" in accuracy is obtained by using even larger balls, bore size to .010" larger than the bore AND .015" or thicker patches. That's what the match & BR shooters use. These types of loads are too difficult to load with the rifle's rod, thus we try different combinations to find what ball size and patch thickness and lube works for us, that gives us the accuracy we want or can get by with, while using combinations we can load with the rifle's rod.
I believe we've found the combinations of muzzle condition, ball size and patching that gives very close to match-shooting results, but allows us to load relatively easily. Is this the last word on this dilemma, absolutely not, but we are satisfied with what we've found.
Not everyone has the same requirements or expectations in accuracy, ease of loading, or type of shooting. What works for us, might not work for you at all, but the accuracy & long shooting strings we get, comes from the ball/patch/powder combinations at which we have arrived.
