Great ammo/Great price

Dialed in at 100 yards with two shots with .300 blackout and 200 yards with .308. Dropped a good sized coyote at 50 yards with the blackout, massive blood loss from exit wound. I use the same rounds with my .308 and every deer shot dropped dead on the spot. Great ammo, great price. No complaints on this end.

Great ammo hard to find

This ammo is the tits pajamas! It mushrooms out very quickly so it doesn’t leave an exit home and causes maximum devastation to the internals! I can’t find the ammo in Washington so I am forced to order on line. This company was great to purchase from and shipping was quick

Winchester Deer Seaspn XP 150gr .300 Blackout

I ordered three boxes a few weeks ago on a Monday and received the ammo the next day, far exceeding my expectations. I received constant updates on shipping/tracking information. This is one of the best ammo purchase experiences I have had. Great job to Gunprime.

I used one box to zero my rifle for hunting season and the ammo was accurate, keeping a small group at 100 yards. I am looking forward to seeing what the lethality of this ammo is. I am happy so far.
