Yes. The guys who put the grease in the base cavity are simply trying to prevent any base wad from sticking in the cavity after the bullet leaves the barrel. The grease is never intended to lubricate anything.
I thought about what they are doing, and decided that it just didn't make a lot of sense. You have no control on how well that grease will STAY in the base cavity during flight, and that is much more likely to send the ball off POA than anything else, IMHO. A good, thick, OP wad to seal gases and thereby protect the skirt on these bullets does make sense to me, as that seems to be the next most likely cause of flyers in these guns. ( Better yet, use a mold with a smaller cavity, and a thicker skirt!)
I think the key for these shallow grooved barrels is sizing the bullets close to bore size, which is what you do, Dave, if I am not mistaken. The grease then grease grooves( as designed) and go shoot the gun! :grin: :thumbsup:
I learned that lesson the hard way, messing around with an imported .45 rifle that had "hint of rifling" in it. After trying two different ball diameters, and three different patch thicknesses, and several different patch lubes, I settled on a combination that I could load without a hammer, and just shot the gun. It proved amazingly accurate( to me!). ?The more experienced members of my gun club would come by to inspect the gun, and when they looked down the muzzle at the " rifling" they would get big grins, and ask me, " How are you getting such accuracy out of a gun with such shallow grooves, if you call them that?"" It became of parade of old members, who on showing up at a shoot, would be corralled by one of the men who had already seen my gun, and would drag him over to see my gun. Giggles and head shakes would follow. According to "lore" my gun was breaking all the rules. :shocked2: :blah: :rotf: :surrender: :thumbsup:
