My son just used Prvi ammo this weekend on a whitetail hunt. He is shooting a sporterized 1891 Argentine in 7.65x53. He was shooting 180 gr. SP and hit a doe at 140 yards through the boiler room. Entry was textbook, exit was about the size of a half dollar, heart and lungs were pretty well mush. DRT, so can't complain. Accuracy has been great, especially for the price.
