either or on the glue / lube
I use Rooster Labs water soluble bullet lube. I tried various glues and did not get the accuracy I was searching for. I think the glue sometimes causes the patch or a portion of the patch to stick to the bullet in flight instead of all of it pealing / blowing off at the muzzle. Recovering some flyer bullets downrange I found shreds of patch 'glued' on the bullet which I believe acted like an air brake or something. The paper patch has to come cleanly and evenly off the bullet or it will affect the bullets flight. The glued patches confetti would be non-consistant in size, like it was not comming off evenly. I found that even just gluing down the edge of the patch gave less accuracy than I knew was possible. I do not know what one might use to substitute for the Rooster Lube. Water soluble yet dries to a hard un-soluble wax. In fact, I now dilute my Rooster to 1/4 strength because full strength also sometimes glued the patch to the bullet. at 1/4 strength it glues the patch down and makes it so tough that I can carry rounds in my pocket with keys and change while hunting and the patch is undamaged. And they are so tough that when feed through the magazine, up the feed ramp they used to catch and tear but now do not. Yes, I try to make everything myself and buy as little as possible but sometimes you just have to admit you cannot do it all and buy what works. You might find it amazing but I must have tried 45 or 50 different kinds of paper before breaking down and ordering some cotton rag bond paper and for less than $10.00 I have a lifetime supply. and I tried all kinds of patch shape before going back to the traditional trapezoid, two wraps w/ no overlap. Every step taken in reloading PP bullets I tried as many different ways as I could think of. Yet time after time I found the traditional way was either easier or just produced better results. I do do it differently than the BP PP shooters but found that the advice I got from the smokeless PP shooters was just easier to follow than to waste a lot of time re-inventing the wheel. One quart bottle of Rooster Lube cost only a couple of dollars and I have shot over 2000 rounds and still have half left. I have patching down to a science and now just concentrate on finding the perfect load for my perfect bullet.
And as per what Fiverunfive said, thats right, Lee sizing lube IS water soluble but it stays water soluble. when used as a patch lube I found it picked up moisture sometimes days later and made the patch soft. Bullets wrapped a couple of weeks before patches tore when trying to load them. With the Rooster, once it dries it is waterproof and the patches are less prone to tear or wrinkle when loaded.
