Something Different

From my collection these cartridges came out a while ago for the 357 Mag & 38 Pistols and gained a pretty bad reputation on their ability to defeat kevlar vests, they were called Metal Piercing rounds made by Geco.
They were called "Cop Killers" the design of the round was that it flattened out like an broad arrow head and well just defeated the vest.
They were banned pretty quickly and to be honest I did not know they existed until my friend gave me one and explained what they were.

So I read up about them and sure enough there was discusions about them and what they did being removed from the market quicker than a slippery lizard in a mud hole.

Gunbroker had one for sale I spied in their Vintage Ammo for $30/USD!

I have a box of these around here somewhere but not by Geco.
Western, maybe? It’s a yellow box.

Bought for resale then was unsure of the legality so they’re gathering dust somewhere haha.

Years ago factory cartridges were available in both 38 special and 357 magnum with armor piercing bullets for law enforcement. These are not common to find.

My photo shows some variations of a small sampling of 38 special and 357 magnum cartridges.

The 357 armor piercing is in the bottom row next to the 41 magnum cartridge

The GECO loads are rare to findAttachment 124106

I believe here I have a 38 Spl tracer and a .357 AP as well.

Nice RCS & BAR I lost myself on GB's ammo page boy if I had a few spare $0000's I'd have an awesome collection though I thought $1500/USD for single Nordenfeldt rounds was a bit OTT.

Rather than buying these expensive cartridges for my collection, I made dummies out of aluminum. the dimensions of the cartridge cases can be found on the internet so the exact size can be reproduced.

I made the German 7,92x94mm first, this was the 13,2 German WW1 anti tank cartridge for the Mauser 1918 T rifle necked down to 7,92mm and rimless. There was also a tear gas capsule inserted into the bullet thinking it would disable the tank crew (did not work).

The second cartridge that I made was the Polish 7,92x107mm for the Polish KB wz 35 rifle. This cartridge fired a 225 gr bullet at 4180 fps (short barrel life too).

my photo shows a standard 7,92x57, Polish 7,92x107 and a 7,92x94Attachment 124108mm

RCS, Nice work on the machining . Do you have a lathe with CNC or taper attachment? I offset the tailstock for tapers but its difficult to make any kind of accuracy. Salt Flat

I tried that but couldn't get much out of it. Mine is too small I guess.

When turning such items on a one-off basis (chamber reamers, etc.) I do an accurate drawing then step-turn the item in .005" increments, finishing off to size with a clean mill file. For taper-turning barrels I off-set the tailstock because of the number of passes required. Another way to easily taper-turn short items is to set the angle on the top slide. If you know the taper in inches per foot you can clamp a suitable length of bright steel flat in the tool post and set the taper with a dial gauge.

These are getting a bit scarcer to find nowday's an original one in reasonable condition a W.H & S 1918 bandoleer, as they were basically a throw away item with being cloth they did not like the elements all that well so for 104 years of age I'm pretty chuffed I was able to acquire it.

I don't store the MKVI ammo or the WWI charger clips in it I have a repro WWI by marching order for that, actually the WWI charger clips are getting like the MKVI ammo hard to find any great No.'s of them think I have bout 30 of them.

(I see in pic#2 the 2nd round on the left clip is not correctly positioned in the Up position.) ;)
