I am having trouble getting my gas checks to stay on my bullets I am using the RCBS 405 FNGC bullet for 45-70 and hornady gas checks. I am sizing using an RCBS lube sizer and .458 sizer die. After running them throught the lube sizer the checks will sometimes stick to the sizer die plunger instead of the bullet. what can I do to remedy this? thinking I might try beagling my mold to make the bullet a little thicker
