What the hell was my wife doing helping you size bullets?

Use real soap, not detergent. Distilled water saturated with Ivory soap is slick as snot.

Ivory soap is also good for a float and attractant for catfish.
Last GC mould I had Tom make the shank 2 thous smaller and no problem (hornady GC). Snap on the GC, size with Lee just a tad larger so no Cu curls. Shake PC and resize. No problem. The NOE expander I have to pry the GC off the tool, nada.

I designed a couple of .30 caliber moulds which have a bell-shaped check shank that perfectly mimics the inside shape of a Hornady gas check that has been sized to .311". Tom's catalog has them.

I find myself using home-made aluminum checks more and more these days. Preparing them is a little work. But this is partly compensated by the fact they seat effortlessly.

Homemade would be nice if you had the dies. Pat Marlin is in the middle of all the fires out in Cal. Freechex is not making anymore. Found one other guy but he wanted $160 + shipping. I don't have access to a lathe or the Vertical mill I used to be able to use.

Pat Marlin has been slow for as long as I can remember. He offers some really neat stuff, but the waiting period in the past really cooled my desire.

I'm a product of the "instant gratification" generation.

One thing about Pat. He is off grid. His electricity comes from solar. He is right in the middle of all the fires right now. He has a note on his page stating this and there is going to be a delay till the fires are gone.

Pat hasn't been off grid in nearly ten years as far as I know. He rented a shop and moved all his stuff there after he got divorced.

I like instant gratification as much as the next guy and also understand that patience is the name if the game with one-man operations that produce boutique items, but I also expect business to improve their model over time. Some do, some don't.

Yup. That's why I use a separate/loose press ram to do my GC expanding. One tap with a mallet and all good, just put them in a can lid when finished.

Can you give a little detail on how to use a vertical mill to make the dies? I have seen instructions for the lathe, but not a mill and I only have access the the vertical.

I'm not following... how are you getting those GCs off with a mallet? I was excited to get my GC expander, but it's pretty much useless with the effort it takes to remove them. Process is far too slow. Rips my thumbnails to shreds too. I thought about lubing the expander, but then I have to clean checks.

I wasn't clear when I described what I do--sorry about that.

I bought as a spare part the press ram that fits the RCBS Reloader Special press. You have to order the retainer spring with it--don't ask how I found that out. And it will require a bit of trimming and fitting, nothing radical--but like a Ruger BH they come in semi-finished/kit form.

Assembly completed, I snap the proper expander into the ram, and use that unit like a center-punch. I sit the check on a chunk of 2" x 4" scrap lumber, center the tool in the check cup, and give it a tap with the rawhide mallet. About half the time, the checks fall free; when they don't, I use a played-out common screwdriver blade to prompt them off. I can do 4-10 per minute, depending upon how motivated I become and how interesting the ball game becomes on the shop TV. I am so darn spoiled, but most of us here have known that for 2 decades.

IME, you don't need to fully spread the check's cup to have the (e.g.) Hornady or gator check fit easily onto a Lyman casting's check shank. A light tap gives enough spread to ease fitment.

If the checks are sticking on the NOE expander then The angle of the expander is wrong.
I found that as check size went up or down from 30 that the angle needs to change. Small changes made a difference. It came down to making the angle on the lathe and before cutting off from the base stock I tapped a check on and made sure it came off easily with a little push. If it stuck then the angle was changed.

Having Made a set from 22 to 45 for Khornet I got a good feel for what works.

@Brad , some "borrow" and copy designs blindly without understanding the nuances of their function. Kind of like the ACE 310-230.
