Gentlemen,
I have only been casting for 3 months now, but am enjoying it tremendously, as well as this site. I have acquired many physical tools as well as knowledge here.
I recently got a 429-421 mold from a member and really like it. So much that I got a mold that is similar but uses a gas check (cant remember the number). Anyway, I also got a lyman 450 and some .44 gas checks from other members. So here is my question:
When I'm using the seater stem hickey for the 450 do I want to use a sizing die one size smaller? I am planning on sizing these boolits to .430, do I want to first seat the gas check with a .429? That way once the check is crimped on when I go to size and lube the boolit the check won't run the .430 die.
I may be overthinking this, I just want to make sure.
Thanks,
Ken
