I have been getting into this also. Still in the learning stages, but so far results have been promising.
I originally got interested in trying this to see if I could improve the cast bullet performance in my 5.56 AR.
These are vary difficult to get satisfactory results. Speed/Twist/gas needs for the action. Way too easy to over twist the bullet.
Initial results are promising. Loaded at starting jacketed load of H335
They held together fine and accuracy was much improved over my best cast load.
Too early to call it a success, but it sure was no failure. More work to do.
But I have beat the best of
MY cast loads 1st time out.
I had not really even considered coating pistol bullets. I have more than enough ways to size and lube them. Dont really have any loads that dont work.
Then I decided to see if they can be run through my Bullet feed dies.
The results may have just made me a full convert.
I have been dinking around for over a year trying to get cast bullets to feed with varying degrees of success. Eventually all lubed bullets end up gumming up the dies and a dissemble and clean needs to be done. Really defeats the perceived productivity gains by using a feed die.
Coated... Perfect feeding. Period....
Also finding I can size a bullet smaller than I normally would.
I.E. LEE 105 gr swc. Since I dont need to worry about maintaining adequate lube grove volume. Sizing to .356 is no issue.
I am using the HF Powder coating machine. Your not saving any work compared to standard lube. Actually is more work.
So in my Opinion, for guys that already have all the lube sizer ect. There needs to be other reasons to do it.
Hence my playing around with things standard lubed bullets dont do well. Leading reasons is not a reason. If you getting leading with standard lubed bullets. Your doing it wrong.
