Lubrication for slug shooting.

What is your preferred lubrication?

I recently acquired a texan .257 and while the AVS slugs I ordered for it that shoot incredibly well are clean I still decided to run them through my ultrasonic cleaner and then lube them with a coating of ballistol.

With that said I shot 130 slugs I cleaned and lubed myself before diminished accuracy occured :O


The next day, I shot straight out of the box AVS , 70 shots before I noticed the accuracy diminish.

So it seems there is a benefit here, I have been cleaning and lubing my 44.75 pellets I shoot from my paradigm and I barely have to clean it.
 
Slugs fill grooves, due to more contact, pellets have very minimal groove contact and rarely "require" cleaning, or at least much less frequently.
I shoot A LOT, it isn't uncommon for me to run through 500 rounds minimum per week if not more. I typically clean my pellet rifles once every 2 tins or 1000 shots, since ive been cleaning and lubing its taken less passes to clean, the slugs definitely will lead a barrel up faster due to the bearing surface thats for sure.
 
I use a little pure silicone oil on a foam in a dedicated old pellet tin. Then I transfer whatever slugs or pellets I am shooting at that time to that tin and roll them around before loading up the magazine, wet. Accuracy never falters and cleaning is simply dragging a string with a few tight patches through.

Do you have any experience with powder coating?
Years ago I was experimenting with powder coating slugs. A guy on here called Trinitymaker (I think) had a topic about it. Personally I never was happy with the effort vs the rewards. I recently revisited testing some powder coated slugs in my best rifle trying to extend my shot count cleaning intervals. It did not like powder coated slugs at all. Once I realized it was going to start me down a whole new path of buying smaller diameter slugs, then powder coating them and testing, I just went back to lube. Your beeswax idea is going to work. The data you are going to need to focus on is how does your gun shoot after it sits 3 days after you shot 25 shots. Then the gun sits a couple days and now it has 55 shots on the liner. How accurate are the first 5 shots. Does the gun get progressively worse or stay the same for the first couple shots after it sits as the liner gets dirtier.
 
Do you have any experience with powder coating?
Yes I've used shake and bake powder coating method to do. Abt 300 lbs of .510 cast powder coat slugs. Can do 25 lbs of slugs at a time doing shake and bake powder coating. Watch Elvis ammo on YouTube......
