i like the Hammer bullets ,this year out of our 257 Weatherby mags. we plan on shooting 103 gr. Hammer bullets at a average speed of 3680 fps these Hammmer bullets group well too. today at 300 yards my group was only 3 shots 1 1/4 inches .this is a hunting rifle for deer and antelope that i will use out west so i don`t need to shoot it all day long for groups besides it was 87 degrees and humid. good luck with your choice of bullets,Pete53
