Home Forums Reloading Bullet Casting Gas Check seating/crimping?

OK, I finally got my top punch for my Lyman 450 and my sizing die, and my M expander die. I think I got it put together correctly but have one question...<P>With the Lyman 450 I got this part that is called a gas check seater. There are no instructions (like with the rest of the press) on how to use it or where it goes on the press. HELP!

Blammer, I have two Lyman machines. One without the gas check seater and one with. I couldn't figure out how to use that little piece of tin either, and I've been seriously loading gas check bullets for thirty years. What I did was put the gas check seater away in a very safe place. I stick the gas check on the base of the bullet (nice and straight) and size the bullet. Sizing the bullet will install the gas check. If the gas check is loose on the base of the bullet and tends to fall off, push the bottom punch down slightly with the top punch (no bullet). Then set the gascheck in the die and then size the bullet. You will then be doing it the way we all did before the gas check seater was invented. Without the gas check seater I manage to get enough 1"-2" groups at 100 yards to be interesting. Hope this helps, curmudgeon

Yea, thanks, I was going crazy trying to figure it out! Glad to see I am not the only one who can't figure out the "obvious". LOL!<P>I seated, lubed and sized 5 bullets last night, and loaded them up. Was gonna go to the range to see how they do, but the truck had to go to the shop, tranny going out or something. No truck, no shooting, can't take the 66 Mustang in the mud...
