5.7x28mm-based wildcats

Post by Esteves » 02 Dec 2008, 13:23

This thread is intended to lure in all of the wildcatters.
  • 4.4x28mm (AKA .17 Skeeter)
  • .17 Velociraptor
  • The various OTTRs up to 6mm from OnTarget
  • .20 shrike (AKA 5mm Shrike)
  • 5.65x16 (same idea as the .22 Epperson Cricket)
Did I miss any?

Esteves,
Here is some more info on wildcat cases based on the 5.7x28 case.

The 17 Skeeter (designed by Rogervich) is based on the 25 ACP case.

The 17 Velociraptor (aka 4.4x28 or 17 V Raptor) was designed by Foxhunter and based on the 5.7 case.

The 5mm Shrike was designed by Rogervich and is based off the 17 Kit Fox reamer along with the 19 KF, 20 KF, and 22 Kit Fox cases designed by me. The PTG Reamer print # is 9361. All these cases are based on the 5.7 case.

I would post the reamer and other photo's etc, but I am not that plastic box savy. :(
Tia,
Don

Ok, I know what you are talking about, the rimmed 5.7x28 is actually the 5mm conversion that Schroader designed and built for the Rem 591/592 series of 5mm Rim Fire ammo that Rem stopped producing in the middle 1970's.
Here is an article on Schroeder's conversion kits to convert to the 5mm Center fire rounds. The Centurion Co now produces NEW 5mm ammo for these rifles etc.

Hello, how it's possible that the PSM cartridge is a necked down 9mm Makarov?
5.45x18mm - base/rim diameter is 7.64 mm
9x18mm - base/rim diameter is 9.95 mm

Am I missing something?

"Don't forget about rimmed 5.7x28"

This was my favorite round when I was 15 years old shooting varmints in Colorado in the early 70's. The 5mm Remington rim fire was one of the best guns ever, like a fine old dog memory. At the time I thought how it would be great to reload. That must be why the 5.7 x 28 is so appealing to me. Hope the 5.7 does better than the 5mm.

I know how you feel, 9th. When I was 15, I too wondered what a great application teflon would be for space-aged materials and I thought how it would increase the lubricity of the bearing surface.

LOOOOOOLLLLLLLLLL

I like how, at the age of 15, you were already more mechanically advanced than I will ever be.

FMYLIFE.

The 5.65x16 was called the Fat Cricket, as I remember I only made 5 cases as the 5.7 was cut to length, inside reamed witha parabolic ground reamer, anealed, and necked to 22 caliber. I still have the test rifle, but performance was not much better than the 22EC and a lot harder to make the cases.

I've got a 5.45x18 case around here somewhere that a contact in the Czech Republic sent me ,it has the 25ACP rim and body diameters. I'd still like to find a 22/25 set of "Sister Pistols" that allow a 22 barrel to drop onto a 25ACP frame and make a 22EC PSM.
