Accuracy difference in various PC powders

[Michael]

This may be a completely stupid question, but not one I am going to try and sort out on my own.
Presuming a set standard that a given powder provides uniform coverage and adheres well, is there any difference between any of the various PC powders and accuracy, with the *ONLY* variable being the PC powder itself?

I've not observed any difference, but I can't say I've done a proper test, either.

There are enough variables related to shooting cast bullets to contend with the it is already. No way I'm about to start trying to sort out which PC powder may shoot better. My wife already thinks I have one too many squirrels in my attic.

Some questions, I simply dont care ta know, the answers to.

Im completely satisfied and dont need to question this for my use.

Have you have issues that lead you to believe this may be your problem?

Nope. No problems, Just curious.

Same here.

I have noticed that some powders give a nice coat that completely covers the bullet, whereas others are somewhat splotchy in coverage. Does it make a difference in performance, I haven't been able to detect any difference.Sandray44@msn.com

My 2cents.
Some PCs coat thicker then others so yes and no.
Yes, maybe, if you don't size after PC. No if you do.
As far as blotchy, as long as the driving bands are coated, no isues.

As per my experience. Now you might want to go with a heavier coating, if you are pushing the limits of the lead bullet. Using the powder coat as a strength adding jacket instead of lube. Say on something like .223. Lead bullet ran close to factory jacket pressure. BTW That was an interesting lesson in variables and Keeping things consistent. One which I have no desire to go thru again.
