I just throw em in the oven on a cookie sheet @ 200 degrees for about an hour and that usually does it.
I also try and knock all the water off in a towel first. I find if I do this I get less hard water stains.
I have noticed some clumping of my powder if I start dropping charges into cases that are still wet but I have never had any issues with those not firing. I generally let them dry though.
Isnt the lube supposed to not interact with the powder?
I have had a similar bulge using Dillon crimp dies and berrys 146 RN. Though, I have never had any issues with them not fitting into my chamber checker and certainly no issues with feeding.
I have a columbia vest that I bought at REI. I have been using it for a while in tier one matches and havent had an issue but I believe it is a little too short. Have been looking into one of the armadillo vests. A lot of guys I see have those and seem to like them.
The same thing happened to me, bought brass and it had some nickel. I reloaded it and it is great!
I dont notice any better feeding but it did feel like it went through my press a bit smoother. (XL650)
