In the past two months I've purchased 7-8 boxes of Hammer bullets and shot four of them. The ladder tests have been easy to acquire zero, finding accuracy nodes in 12-15 shots for each rifle, I'm prepping two rifles for a Safari this October.
Fouling has been minimal and accuracy terrific. Both rifles are shooting sub MOA. My 338 Federal is sighted in at two inches high at 100 yards and its effective POI is 230 yards. My second rifle, a 270 WSM is sighted in at 200 yards and has an effective POI of 340 yards.
What impressed me was the overall accuracy and bullet weight retention. Based on available data the bullets are retaining over 90 percent of their original weight. In short that translates in my 145 grain 270WSM retaining approximately 130 grains of weight, and my 225 grain 338 Federal retaining over 202 grains of weight. Those numbers combined with incredible penetration make for an exceptional hunting bullet.
One of the ten animals I'm hunting this fall is Eland and a 2,000 pound antelope demands a bullet with exceptional weight retention and outstanding penetration. I'm convinced that the 225 grain hammer bullets will provide both.
