Why do I need to expand gas checks?
« on: January 07, 2018, 07:23:46 PM »
I have the NOE 311-180 RF (GC) mould.  The gas checks are from Bullet Swaging Supply, Inc.  Presently I bevel the bullet base with my thumb nail, set the GC on the RCBS .311 die and using the Lyman GC Seater. I center the bullet base on the GC and carefully operate the ram. Occasionally, I screw it up and have a reject. I have also tried seating the GC with the bullet nose first and base first through my Lee .311 push through sizer.  Neither works correctly. Am I doing something wrong?  The hardness of my lead is unknown, it's not soft, the ingots ring when they hit the cement floor. I'm trying to keep things simple.... Thank you.  (My next order is for the NOE push through die and bushings)

Check the shank size on your bullet and the gaschecks

List of Hornady and gator check sizes here: http://www.castpics.net/subsite2/Classics/Gascheck%20Shank%20Sizes%20and%20Diameters.pdf

It sounds as if you have a hard, high antimony bearing alloy which will give your bullets a greater over all diameter than a softer alloy

Thank you for your reply. I think the Bullet Swaging Supply will work fine. Being new at using gas checks, I didn't know how hard or easy this was supposed to be. Thanks. Tom

An alternative to expanding the gas checks would be to use the NOE gas check seating die.  I love using that little die to seat the checks on tighter fitting checks--and it does it very well, nice and square.  Remember it only seats the gas check--they still need to be crimped on.

Thanks!

I have my grandpas Lyman Mag20 melting pot, it was left 3/4 full of unknown lead mix. I cast 400 nice looking  180 gr Sil bullets for my 357 Max. But I am having trouble sizing them with a gas check. Some of the bullets get stuck in the sizing bushing. Might it be a lead mix that is to hard? I tried running a few through the bushing without the gas check, it was hard going on some of them but none stuck. I then ran them through again with the gas check in place, but instead of a flat gas check on the bullet, they are dish shaped once they come out of the sizing die. I planned on powder coating, if they are to o hard can I use them without a gas check and get no leading? My bushing is a .359 and the mold is a N.O.E. 4 cavity 180 gr RCBS Sil design.
