I believe it was a shortened 221 FB die. Larry

I think someone is looking for a problem where none exist.
Just cut the barrel off a 223 however much you want it short. Do the same to the 223 die. If you don't have a 223 chamber, use a 223 reamer. It's best to make a case first and use that for a headspace gauge. If you can't do it your self. have a gunsmith chamber something that is already established. What you get is a lot of farting around for no gain. my 2cents Kenny I have made several for one reason or another.

If you cut off a .223 die to make it a .223 short you will have a base that is far too small to go over the case head and a shoulder that is small. Even the FB die shortened was a little tight at the base. When I shorten a die very much, I just make a little plug to fill the top, put the shoulder taper on the top and the new shoulder taper in the bottom, make the neck whatever you like. I made up my 20BR and the 14 TCM dies this way. Just find a parent die that has the right case head size and body taper right and you are all set. The stem is hollow for the decapping rod I threaded the top to make sure it stayed in, just put a nut on top. Larry

Man I feel dumb when you guys start talking about making your own dies and chambering barrels. Its a heck of a great skill to have.

Here is the story pretty much from the beginning:

I like the idea of the "factory made" 22 TCM brass. It's right from the start even if it's a little on the short side. Any shorten brass will get the job done. The less work it takes to form GOOD brass, the more time for shooting!!
The issue I ran into while trying to make just about "any" short brass is finding a die that is big enough at the base opening. You shorten any die and you deal with not enough taper. You can run the brass into a shortened die but you end up "scuffing" the case body. Then, you have to deal with trying to get rid of the"scuffed" portion (ridge) on the lower part of the case. If you had small enough tools to cut, a hone or even a reamer small enough to open up the base of the die, you could get past that problem. The upper part of the die isn't a problem. Pick a die with the proper neck size and shoulder angle for your project, open up the bottom to cure the scuffing and you're almost there. I'am thinking of going full length "bushing" die, that way I can take the case neck from 22 to 20 or even 17 just by swapping bushings. 20 reducer on a 22 case neck (TCM) leaves the neck too small to start a bullet in. Still trying to sort that out. The proper sized case from the start makes MUCH less head aches. |

I have a short 17 Remington that holds 2gr less powder than a 17FB. that's pretty short. I have been shooting it for over 10 years, I shoot 2 short 204s without a problem. I did have a 223 shortened to 21 FB. All done on factory chambers. This problem never arose. I don't use any dies that require the case head to go in them. Shortening a chamber doesn't do anything to the shoulder Kenny

All the dies have a taper in them, guess if you have a very loose chamber you could cut it back and still chamber the end of a shortened round. I don't think you could size a FB length case in a shortened .223 die as the base of the die would be too small for the base of the FB brass. Larry

If you had a way to put the taper back in the shortened die, you would solve the scuffing problem. Lee makes (and is available) 22 TCM die. Only problem is trying to go from 22 down to 20. The Lee die without the primer punch would take care of sizing the biggest % of the shortened case. At least, that's a start. Then you have to deal with neck sizing.
(Shortening a chamber doesn't do anything to the shoulder Kenny)?? Sooner or later you'll have to deal with the rest of the case. The upper part (shoulder/neck area) isn't the problem as long as you can get the case in far enough to size the neck/shoulder area. Just about any die that's close in size (.223/Fireball/20 VT) will do the job. Getting the lower part of the case to "not" get damaged (scuffed) while doing the upper section is the problem. And I'am think I'am not the only one that has run into that problem. Last edited by Nor Cal Mikie; 07-28-2016 at 01:42 AM. |
