I've come across some Hornady 8087N, it's a 308Win 155gr HPBT with all the seals and crimps. Anybody know how it performs, especially head to head with Hornady 155gr AMAX TAP? Any reason to choose it over the above mentioned TAP, other than shooting better in the subject gun? It's not a catalogued product as far as I can tell, anybody know who this cartridge was made for?
