this year i used a 103 gr. Hammer bullets in my 257 Weatherby mag. velocity 3680 FPS was a one shot bang flop on a buck that was weighed and dressed weight of 193 lbs at 125 yards ,blood all over on the ground too. one shot on a antelope buck at a measured 460 yards with my 257 Weatherby mag. same bullet 103 gr. Hammer bang flop too. this Ruger #1 shots 1/2 inch 3 shot groups at 100 yards with these Hammer bullets. 100 gr. Nosler Partitions and 100 gr. Swift A-Frames do the same thing but don`t shoot as accurate groups they open up a little bit put still do the bang flop. next year i plan on shooting a Ruger #1 257 Roberts with 75 gr. Hammer bullets i wanna keep the speed up it kills better for me.
