I size and lube with a Magma tool. I'm considering obtaining a Freechex III, and wonder whether .44 caliber aluminum checks can be expected to seat and crimp properly on a Lyman 429215 with the Magma fed nose first. I seat and crimp the Hornaday checks to good effect in that manner, but have no experience with aluminum checks. Is it necessary to seat and crimp the aluminum checks base first?
