Guys:
One of our customers (www.coilandfoil.com) is having a problem seating his gas checks made with Yonky's material. He is using a Lee push through type sizing die. The die is 22 caliber and produces sized bullets of .225" diameter.
He purchased the copper gas checks from us. They are made from .008" soft copper, possibly C101.
He seems to feel the copper is too thick and is dragging through the die causing what you can see in the photo. I don't have any experience with the Lee push through sizing die and do not have that problem with my Star or Lyman dies. I can use material from .005" to .010" without having this problem. He states he has used Hornady checks and does not have this problem with them. Does anyone have any suggestions? Thank you...Gil - coilandfoil USA Shipping.
Added - I am not sure if he is sizing base first or nose first.
The copper gas checks were made with a Freechex III tool.
