new wildcat... thinking of names...
my retired builder buddy just finished my .416 Rigby ( shot it the 1st time yesterday )
so on to my next project... we are looking at swaging 5.7 X 28 cases down to the rough equivelent of the 5.7 Velo-dog case... my buddy has come up with a 4 or 5 die process, after the 5.7 X 28 cases are fully annealed... because I'm converting a 22 Mag revolver to centerfire, I can load these to higher pressures than the Velo-dog, so we are making the diameter of the case a couple .001's thicker, to keep the new case from slipping into my antique Velo-dog revolver... so... what I'll end up with, is a reloadable 22 mag, in which I can select which bullets the cartridge is loaded with... thinking cast 22 bullets & Trailboss for low end, & Hornet bullets or light .224 rifle bullets for high end... anyone done anything similar ??? got any suggestions for the Wildcat name ???

I read this while back.
9mm 115gr 1250fps 399 ft lbs 5.7mm 31gr 2346fps 379 ft lbs .22 mag 33gr 2000fps 293 ft lbs Our recent tests also show that mass is more important than energy calculated in this manner. Considering this, a 31gr projectile is an abysmal performer. Tests show it does no better than the slightly slower .22 mag in killing even small game. and this http://www.thefirearmblog.com/blog/2...m-vs-5-7x28mm/

OLD ROPER... I like heavier bullets myself ( I've done some work with fast twist 22 Hornet, in both a revolver, & in a converted Ruger bolt action... my fast twist hornets allow the use of up to 68 grain bullets with good stabilization... I have thought of lining the barrel with something faster, allowing the use of 223 bullets, but since this is just a fun gun, I'll probably start with the 22 mag barrel at 1 in 16" twist & see what bullets will stabilize 1st... BTW... I have a 5-seven pistol, & a Contender barrel for that cartridge as well wasn't trying to imply they were anywhere close to the same in performance... been looking at lowest power reloadable cartridges for a while now

not as easy as we had hoped
we were hoping I'd get enough heat from a kitchen oven ( for future forming ) but the cases did not anneal enough using my machinist's tempering oven at 500 degrees... so the household kitchen oven is out...
also the laquer coating on the 5.7 X 28 cases did not burn off at 500 degrees... my buddy is going to try 900 degrees this afternoon & see if they'll get soft enough... ... also there is too much material at the case head, so it looks like at the least, the cases will need some turning in a lathe at the case head/ web area... my buddy did run a couple through a 22 Hornet die just to see how things would go, before making the 1st of the form dies... the pin used to maintain the primer pocket was sized the same as a primer, & it looks like it stretched / snapped tighter after removed from the die, enough so, that a primer would not seat in the primer pocket... so the pin will have to be a couple .001's bigger to get primer pocket of normal size... the laquer coating looks to be highly solvent resistant... anyone that's played with the 5.7 X 28 cases come up with a chemical remover for the laquer ??? of coarse, maybe it'll burn off at 900 degrees ???

You definitely need to name this the .22 Rube Goldberg.

GRIZ... thanks for the link... I'm a member there as well, & am familiar with the CCM ( day late & a $ short ) on getting any brass or load equipment for the CCM though

I just read an article on annealing, it says you should not fully anneal the case, especially the case head. Now I'm sure you and your friend have a lot of experience since you're wildcatting a new chambering, but please consider the safety aspect of a fully annealed case when you are making your brass.
Here's the article: http://www.6mmbr.com/annealing.html |

As already mentioned by thedaddycat.

Take a look in P.O. Ackleys loading book there were several small 22 wildcats based off of the Hornet case.

Sorry, I didn't realize that the CCM was unobtainable. Am i reading it correctly that you have already formed cases? A photo would be interesting. Have you considered starting with the hornet case? It already has a rim and I think the base of it is a not as stout, making forming easier.
Either way, good luck. I like the idea of a "reloadable 22". |

How about calling it what you said it is:
"22 Relo" or a "Mag Relo"

On a separate note... I have been a fan of the centerfire .22 Mag concept for a long time. For a while there, I was even trying to get my hands on some .22 CCM cases. As you probably know, that is incredibly difficult. Which makes me wonder: Why do you want to use 5.7x28mm cases, and not .22 Hornet? The only advantage I can think of, is that you won't have to ream the case necks as much, since the cases don't have to be trimmed as far (if at all). But... the 5.7 case doesn't save you any time during the important forming steps (swaging and lathe-turning). Am I overlooking something, or is simply it a matter of convenience? (Such as having several hundred pieces of 5.7x28mm brass.) I like "FN Dog".

I have some of those case's, as I recall putting them in a slow cooker for a long time, will loosen the poymer coating. It is put on the case's to aid in extraction in the automatic arms for that caliber. The stuff really wants to stick to the brass, but long soaking helps to take it off.
