How much neck is left after necking down a 357 Max case and finshing up the procees with a 222 Remington die. Anyone try it?

Too short. Nice idea, but it doesn't make the grade.

Thanks Mike!

Unless you go for the "Dalton" round.

Falls in between the 221 and 222.

I went and ordered some of the Bertram 222 Rimmed brass just to give it a look over. Also ordered a copy of Nick Harvey's Practical Reloading Manual which lists data for the 222 Rimmed (so I hear). Can't have enough reference books. Maybe sometime in the future a custom 222 Rimmed barrel.

Hopefully the .222 Rimmed Bertram brass is better than some of the other rounds of theirs I have worked with.

Huntingtons used to sell 222 Rem. rimmed brass also from Australia from another maker that looked like pretty good stuff. I have a box somewhere. Will look for it and the name.

If you are starting with a new or shorter chamber than .222 Rem. for rechambering, the neck can be held short and then the Max. brass will work. Neck length turns out to be about the same as a .223 Rem. I either have or can make up a sample case if you want.... just ask. The body is the full .222 Rem. length, but the neck is shorter is all. For a better idea in the meantime, measure up from the base of a Max. case to about 1.6" keeping in mind that the case will elongate some when necked down.

The "Dalton" round is excellent also..... or any compromise in between these two.

Using just the .222 Rem. dies, after necking down, is probably simpler and easier than Dalton's round.

If you want a longer neck, the .222 Rem. die can be shortened some, also.

You see, you don't have to be a genius ballistics expert from Ohio to actually invent new rounds instead of just plageurizing everyone else's work and calling it your own. Excuse the barb.

However, great rounds can easily be developed by enterprising minds such as Dalton's with simple tools at hand. His round is a better round than anything I had thought up!
