The only concern ive had with this ammo is that they have **soft** non corrosive primers... on my particular SKS (not sure if anybody else is experiencing this) every time the bolt flys forward, without firing it; the free floating firing pin leaves alittle mark in the back of the primer. Showing some potential for a possible slam fire ! BUT so far ive shot 100's of rounds of the HP and had no issues

ive shot many Porcupines, and a few coyotes with this ammo, groups around 1.7-2.7" @100 ALL the time.... it being non corrosive is the best part, take it coyote hunting, get back late and have to work the next day, clean it next weekend no problems

AND FOR 25 cents a shot to boot!!
