Hornady TAP 75gr uses a clean burning temperature insensitve powder that gives very little flash. The brass is new and the primer is crimped. It is loaded consistently one round to the next. The bullet is a precision made match projectile, cannelured and crimped in place.
There's nothing "special" about it that can't be replicated, its just most don't do it all. Best bet is handloads, which unless you send off your brass to be prepped, primed and crimped does not have a crimped primer. Better get a cannelure tool too.
It is true you do not NEED a cannelure if you have good neck tension and maybe a small crimp. But it doesn't hurt and it makes the complainers hush. From a terminal ballistics standpoint it's not going to make the bullet break up more or create a larger wound profile. But it MAY help it break up at a slightly lower velocity, again it certainly won't hurt.
Still, I don't get what is not to like about this ammunition? It's relatively cheap for what you are getting.
Why does Federal's LE HST line of pistol ammunition use a different bullet than the rest of their personal defense loads? Winchester's RA LE line of pistol ammo also features a bullet not made widely available to the general public. Both outperform any other pistol ammunition offered in their respective lines. Sure there are phony ammunition scams and marketing. Some "LE" marketed ammo is not that great, no doubt about that. But some are all around great and priced cheaply.
Hey, how many of you have Hornady's new TAP 62gr barrier load? Or ever seen the bullet for that matter? LEO's don't count!
