Seeing a round on another thread - a short, belted .45 round for a sniper rifle, made me take a look at a similar round I have had for at least 30 years. I purchased it from Tom Dunn, who sent me what little information he had, written on the back of a label copy. The box was a common Flambeau Handgun box for .45 & .44 Caliber. The stick on label indicated the cartridge is named .44 Belted A.P. Since it has a soft-nose, HP bullet, I ruled out “Armor-Piercing” as the meaning of A.P. Tom and I both felt it stood for auto pistol. The bullet weight is shown on the label, 240g JHP, and it has a catalog number of 429E196 from BALLISTEK, Kearney, Nebraska.
Tom’s message on the back of the label says: “John, this is all I have on the .44 AMP. I bought quite a number of ctgs from Ballistek - they were new wild-cats and obsoletectgs such as 257 Condor etc. John Donnelly was the honcho of Ballistek (last address is Lake Havasu City, AZ. He could, probably, tell you what gun was used. At one time, perhaps a year ago, he was hand loading editor of one of the magazines. Thanks. Tom”
Note that Tom used the caliber designation “.44 AMP” in his note, but that designation is NOT on the cartridge box, which as noted, says simply .44 Belted A.P. The .45 Automag cartridge was not belted.
The cartridge case used was a Remington “R - P 300 Magnum” headstamped belted case. The bullet is a GM SP HP of semi-truncated shape. The primer is a standard Boxer, with nickeled cup. Manufacture shows good quality workmanship in the conversion.
OA Ctg. Length: 1.608" (40.84 mm)
Case Length: 1.270" (32.26 mm)
Bullet Diameter at case mouth: 0.4215" (10.71 mm)
Case Mouth diameter: 0.44745" (12.05 mm)
Head diameter just above Belt: 0.510" (12.95 mm)
Belt Diameter: 0.532" (13.53 mm)
Belt width: Approximately 0.113" (2.87 mm)
Rim (Head) diameter: 0.5305" (13.47 mm)
Extractor Groove diameter: 0.4665" (11.84 mm
That is all the information I have on it. Does anyone know about when this wildcat was conceived. Can anyone tell me more about "Ballistek? Does anyone know what firearm this was intended for? If an “auto pistol” it would have to have been a big one like the Automag, or the Wildey. Does nayone have any other expalanation for the designation “A.P.” after the caliber?
Any further information will be appreciated.
