Flintfan - the very best target lube I've ever used is spit. I've yet to find or use a lube that will beat it for accuracy or for clean shooting. By clean shooting, I mean softening the fouling so the next ball can be loaded, every time, without having to swab or clean the bore(between shots). It matters not if you are shooting 10 shots, 20, 50 or 100 in the day's time. With spit as the lube, and with the proper ball/patch combo, you don't have to clean except for at the day's end.
: With low velocity rounds, close shot to shot velocity is important for good accuracy. Large shot to shot variations in relatively low velocity rounds, causes vetical stringing on the target. So - the least amount of variation results in the best grouping, without stringing, ie: round groups.
: Spit used for lube, gives the lowest shot to shot variations of any lube I've tested so far. I've tried Bore Butter, Bear Grease, Bear oil, Marmot oil, Baby oil(commercial), Axle grease, HW30 and of course, spit. ALL of the oils exhibited much more variation in velocities & accuracy and poor cleaning in comparrison, with BP as well as with Pyrodex. Pyrodex is very poor with large variations, even with spit. Pyrodex fouled much less, allowing many shots without cleaning, even when using oils or grease for lube. Accuracy with Pyrodex is harder to find than BP.
; Extreme accuracy is harder to get with any lube other than spit.
: For hunting, any non-freezing lube that will allow several shots without having to swab the bore is just fine. The other requirement is that the lube also shoots well with consistant accuracy 1st shot through last. I haven't tried Stumpy's "Moose Snot" yet, but expect to use it or Lehigh Valley for hunting from now on. Which ever shoots the best and allows shooting without having to clean or swab. A major requirement of clean shooting is a tight ball/patch combination. A .010" under ball with .020" patch works in most rifles as well as a .005" under ball and .015 to .018 patch.
