I’m looking ahead to the (near, I hope) future when I start casting bullets. I’m going to be casting a .30 caliber, 150-ish grain bullet for use with 300 Blackout, and the bullet is designed to use gas checks.
I will be powder coating my cast bullets. The powder coating process seems to be very well covered in a few stickies, so at the moment I don’t think I need any real guidance there.
I already have the Lee push-through sizing die, and the info I have found from Lee says that this die will allow me to seat gas checks. But they don’t say how that’s done.
So can someone give me a quick, basic tutorial on how you seat gas checks, in general and specifically with a Lee push through sizing die?
I have pretty well figured out that the bullets should be coated before seating the gas check, but I sort of need to know things like whether I need to do anything special to the base of the bullet when coating it, etc.
Thanks!
