[QUOTE="500yd, post: 733161, member: 27428"] I've witnessed on at least 6 occasions the taking of bucks and does of all sizes at 400+ yards with a 22-250. That is Jamie's weapon of choice for whitetails due to the laser flat trajectory. To add insult to injury, he uses the 50 gr Win BST, which is the exploding varmint variant in .224 caliber. He prefers head/neck shots, but a couple of these he tagged in the boiler room. All of them folded over without taking a step. I know another guy pretty well who has taken quite a few at 350-400 yds with a 257 Roberts and cheap soft point non boat tail factory foddder. I didn't witness these personally. At these ranges both of these rounds are hitting with between 500-600 ft-lbs. It just doesn't take that much energy to put a whitetail down if you hit them in the vitals or CNS, i.e. make a decent shot. Interesting statement. Would you hesitate on a big bull at 500 yds if you were packing a .308 Win with 180 gr TTSX or 175 gr Berger VLD at 2600 FPS MV? Most people would probably reply without hesitation, "Hell no, I'd click my turrets and let her fly". Given this, let's compare the .308 Win load of TTSX 180, Berger 175 VLD, and the 300 WSM 110 TTSX load energies at 500 yards, according to JBM.
