Could you document that please? I can find no reference to anyone being more aggressively prosecuted due to the ammunition being used.
An excerpt from a Firearms Tactical Institute publication in 1998 indicates tha distributors sell supposed LEO only ammunition to the civilian market.
(Part III lists data for several cartridges which have been discontinued, such as the Winchester Black Talon, .38 Special 147 grain cartridges, and several others. We're well aware that many of you might have some of this discontinued ammunition and this information is of value to you.Also, we expect to see a flood of law enforcement only Winchester Ranger SXT [the law enforcement only version of Black Talon] on the civilian market as law enforcement agencies opt to purchase the newer Ranger Talon and distributors sell off their stocks of unwanted Ranger SXT ammunition to the civilian market.
Therefore, if you do not see a cartridge listed in Part I, this doesn't mean that we haven't published data for it in the following sections.)
I bought some Ranger SXT last week to compare against Speer Gold Dot through Chronograph testing, the retailer did not ask for LEO ID.
