I have been archive searching for a good hour now... various search terms. Most of the information on Tumble lube vs Pan Lubing is about the application, directions, and recipes. I find very little information on the accuracy between BLL and stick lube.
I realize, that each rifle is a law unto itself. I'm trying to get a feel of the general consensus here about accuracy. To give me an idea if I want to invest more time and money into stick lube.
Let me also say, that I have had zero leading (properly sized bullet) with straight ALOX, 50/50 MS/ALOX, BLL, or the 4 different stick lubes that I have tried. I have shot all lubes (except straight ALOX) to up around 2200fps. Again with no leading. All lubes perform (leading, fouling etc) perfectly. Just really bad accuracy for all lubes.. which is understandable because that's a result of the bullet, my rifle and the really fast speed.
When I reduce to typical cast bullet speeds (1700 to 1950fps), I notice accuracy differences between stick lube vs tumble lube using BLL. The stick lubes all perform similar among each other. One generally has a slight .5" group difference. On the other hand, BLL tends to better accuracy. Groupings .75 -1.5" better. Slow down further to around 1600fps both types lubes have the same accuracy. In fact, both types of lubes have the same accuracy from 1050 to 1600fps. Problem being that 1600fps is the around the fastest speed I have gotten a stick lube to work for me with accuracy I can accept. But it's not a velocity I want to accept.
I cannot wrap my head around why this is, and that's where I need help and looking forward to a lively discussion.
Caveat: My tests are no where near extensive. I find a powder that works well, a bullet that does okay, and load them up the same with different types of lubes. I use 3 shots generally to foul the barrel and hopefully remove the last lube. I'm not proclaiming a conclusion. I'm looking for ideas as to why I'm experiencing this.
