The easiest way to make brass for this is size 17 Fireball up, or 221 FB down. Of course, I had to do it the hard way! Took quite a bit of research and practice, but my donor brass of choice is Lake City 5.56, and through a bunch of steps, convert it into cute little 20 Vartarg brass. Currently, Lapua no longer makes 221 FB, and Remington doesn't have any on the market, but you can get Nosler 17 FB brass. These are the main stages, (along with trimming, annealing, neck turning, etc).

What diameter does the Redding 90101 forming die take the body where the neck will be down to?The easiest way to make brass for this is size 17 Fireball up, or 221 FB down.

The first forming takes the neck to .2975" diameter. The bushing die, with no bushing, takes it to .2500". I size the first two, and then anneal the neck and shoulder, and do the 3rd final sizing with the body die. Otherwise, the brass is getting very work hardened, and can have issues getting a consistent amount of shoulder height, etc.What diameter does the Redding 90101 forming die take the body where the neck will be down to?

Thanks, I've got some of your 20 Vartarg brass but I may have the easy way covered also as I've got 500 x 221 Remington cases.The first forming takes the neck to .2975" diameter.

Since you're in New Zealand, I'm curious how you got ahold of some of my 20VT brass?Thanks, I've got some of your 20 Vartarg brass but I may have the easy way covered also as I've got 500 x 221 Remington cases.
Those Redding 90101 forming dies aren't easy to come by and aren't cheap when you do find them, so a bushing for my Skip Otto form die might be the solution.

That's very nice.View attachment 234
Others have used the Harbor Freight miniature chop saw, but I did a wood-working project instead. This is to get the .223 and .222 cases to the approximate length after going through the .221 forming dies. The Dremel cut-off wheel works fine. Still on my first one. I do wear a face shield when using it, since they probably don't fail gracefully.
Yup.That's very nice.
Could you possibly put a plexiglass shield over it?
It was quite a while ago, a buddy bought them and I bought them off him when I was in the USA and bought them back.Since you're in New Zealand, I'm curious how you got ahold of some of my 20VT brass?
In case you need more, I have 1300 currently available, and also have 50 of Remington 221 FB brass, and 200 I made from Lake City.
