Fix my lube

All this is beginning to sink in, Ian. Keep at me, I'm getting a feeling that "I think" I'm understanding it. So adding 20% Vaseline to the BAC will lower the viscosity enough to work with my low pressure loads?
Which would benefit me more, the Vaseline or the ATF?
Either one. I tend to use Vaseline. I find it easier to mix in and it has no odor. If you use ATF make sure to use less, it reduces viscosity well with far less.
Some of this is a good learning experience. Try 5,10,20,30 % Vaseline. Shoot the same loads and see how lube changes the group. Watch for those dark rings.
Repeat with 3,5,7,10 % ATF and reshoot.
Seeing can be believing.

We have officially entered the Esoteric Zone
After a while you can tell by feel how lube will work in a particular application, or what needs to change to meet a certain need. Acquiring that feel doesn't happen overnight.
At low powder pressure with a relatively tough alloy, the bullet can smear lube the whole length of the barrel and ride on top of it. Sounds good, right? Problem is that layer of lube varies shot-to-shot, and as the barrel heats up it can thin out and take a load from ok groups to wild flyers as the bore condition changes, bullet friction changes, and as a result the pressure curve changes.
The name of the game with lube has pretty much been nailed down by a friend of ours (Pete) by attaining a state he called CORE, or Consistency Of Residuals Encountered. Getting that first, cold-barrel shot to last, hot shot, in any weather, with no cleaning during strings, totally depends on the friction and residual powder/lube fouling in the bore remaining consistent overall. A very tall order indeed, but not so bad if you stick to a ~50° temperature window and formulate your lube for the pressures it will see.
I'm beginning to understand, I think........................though I've a long way to go. Though, initially, this was all confusing, your repetition is sinking in and I think I'm beginning to get it.

I will, later! I've got 30 rounds that have "my" lube and and equal amount of Vaseline. Mighty slippery. We'll see what the targets look like.
Yes, that is what I mean.
The danger Will Robinson is because you will get sucked into lube testing. I did tech same years ago and my home has never been the same. No matter what do NOT make a sodium stearate/ATF grease on the kitchen stove when your wife is home. Just trust me on that one.
Actually, it isn't that bad. It just leads to lots of very odd discussions about lubes. Ask fiver about early morning runs into the snow.......

I can't fix your lube....I can send you a couple sticks of Glen's moly to try if you share your results here.

Nice of you to offer. I may take you up on that at a later date. Seems I have my cart filled with tests to do as it is. (50% "my" lube/50% Vaseline...........50%Bees Wax/50% Vaseline............Bees Wax and 20%, 30% 40% and 50% Vaseline..........and then all of the same with ATF II !!!!!) Beginning to wonder if I'll ever get to shoot for fun!!!!!!!!!!!!!!!!!!!!!!!

Your doing it right.....learn learn learn. It's a journey for us all. I try to keep some sanity to it. I only have 6 lube types & 1 coating system.

Umm...that didn't include black powder lube though. Even with those I'm still under the 3 Amigos first shelf.

Well mine is powder coating but, many types of coatings are being used today by many.

Chris, don't get derailed on the winding, treacherous siding of lube experimentation until you have a positively excellent load worked up as a base-line. You're a ways off from that yet. Just make something soft and not too damned slippery and if the color of the rings around your bullet holes is all the same then resume the other parts of the load testing. Paraffin oil (Dexron III ATF or heavy mineral oil from the medicine cabinet) or Vaseline (mixture of microcrystalline wax and mineral oil) will soften a lube without making it any more slippery.
