Does anybody know what type of ammo comes in brass with the headstamp



FEDERAL NT 40 S&W



I'm asking because for some reason that particular headstamp doesn't like to be reloaded very well. I think the primer pocket is smaller then a small pistol primer ..... yet the headstamp FEDERAL 40 S&W doesn't have a problem. So what is the NT for???

Federal Cartridge Company BallistiClean®

This ammunition uses a copper jacketed, zinc core bullet, a nontoxic copper-colored primer and is loaded in brass cases head stamped “NT.” The primer mix is of particular interest as it contains no heavy metals or toxic metals; instead, the primer mix contains DiazoDiNitroPhenol (DDNP) as the primary explosive instead of lead styphnate. Furthermore, the oxidizer is calcium silicate instead of barium and strontium compounds. Indeed, this round is reportedly the first completely toxic metal-free line of ammunition to be developed. The BallistiClean round is designed to exceed OSHA and EPA requirements, protect the shooter’s lungs, eliminate disposal problems for range owners and operators, and sheds approximately 50% of its weight upon impact, thereby reducing back splatter. Furthermore, this round provides an enhanced realistic training experience because of its ability to duplicate the accuracy and recoil of standard duty ammunition. These loads also cycle reliably in semiautomatic weapons. To date, this ammunition is available in numerous bullet weights for the following calibers: .380 Auto, 9mm Luger, .38 Special, .357 Magnum, .40 S&W, 10mm Auto, .45 Auto, .223 Remington, .22 Long Rifle, and 12-Gauge shotgun.



HTH,

Reads like a microsoft answer ...... Technically 100% correct yet totally useless LOL




But I took a look at thier site, reading all that info the best I can gather is that perhaps the NT cases are used with thier TMJ rounds. They so state that thier TMJ uses primer 205TMF vs primer 100 for thier other 40s & 9mm rounds.

But when I go to thier Components: Primers and Wads page 205TMF isn't even listed. Thier small pistol primer 100's are listed as 0.175 diameter, I measured the inside of the primer pockets of the NT cases and I'm getting 0.171-0.172 ..... thier non NT cases are 0.174-0.175.



So my guess is that this is probably what's causing the issue here.
