Have a mold that casts the proper bullet for the .351 WSL, Ideal #350447. Diameter is .352 which is good, but it is a gas check design and I would like to use them. I will assume I can use a .348 sizing die to crimp the gas checks on. Does Lee make special diameter push through sizing dies in .352 or can I buy one for my RCBS lube-sizer from someone? The base of the bullet measures .326 where the check crimps on.
