This Wildcat is Made from 5.7x28mm Empty once fired Brass by Swaging it down in diameter to .276" Diameter then Trimming it to .960" case length.
This ends up a 'Semi Rimmed' case as the Original rim is left as Was.
I am using bullets of .250" to .252" diameter and Crimping them for Starting Resistance at propellant ignition.
A good Bullet seems to be the Hornady #2510 (Jacketed Soft Flat Point 60 grain) sized to .250" diameter.
I am also collaborating on development of a Swaged Lead 67 grain .250" diameter Wad-cutter/Hollow Point Reversible Lead bullet for use with .25ACP, this .25ALR, and other similar Caliber Wildcats.
To date none have been Loaded And Fired yet due to my poor financial condition at the moment.
However; i have loaded a few Dummy samples to try as Function Test Items.
Left to Right: .25ACP @.905" OAL; .25ALR @1.293" OAL; .25 Magnum Auto. @.1.366" OAL; .25ALS @ 1.407" OAL. All With .250" sized Hornady #2510 60 grain Jacketed Soft Flat Point Bullet.
Note: .25ACP Case Length = .612"; .25ALR Case Length = .960"; .25 Magnum Auto. Case Length = 1.055"; .25ALS Case Length = 1.125".
