after some almost failures with a couple of other brand bullets i now only use 100 gr. Nosler Partitions and 100 gr. Swift A-Frames in my 257 Weatherby mag. i have never had a failure with these 2 great bullets and that is in probably around 30 some years and 20 years in a 257 Weatherby mag., so i have stocked up on these 2 bullets . i wanna mention this while using 100 gr. Nosler Partitions and / or 100 gr. Swift A-Frames we have never had a buck Whitetail or Mule deer buck go farther than 80 ft. with 1 shot out of our 257 Weatherby mags using either of these 2 bullets for me 20 some years son 10 years . many of the Whitetail bucks would weigh over 200 lbs. live weight some up close to 300 lbs. live weight these were bucks shot by the Canadian border in Minnesota.
