My 257 really shoots the factory hornady 90gr GMx ammo really well too...that's where I started with reloading. Box of bullets later I figured out I needed to crimp the cannelure to make them shoot. I've shot 9 deer with nosler ballistic tips and was exceptionally happy with the performance on all except the last deer. Shot him close and the bullet possibly turned inside out, carving a 2" channel. He ran about 100yds and died. The bullet still performed but not as well as the others. I only shot one with a vld and it pencilled through a deers heart so I went back ballistic tips that I know will expand. I shot 3 deer with the gmx and wasn't ever really impressed. They punched a hole and the deer died but usually they jumped then walked around with a hump in their back until I shot them again. But seeing how many of ppl have good luck with Berger bullets I probably had the one off and stuck it between ribs. Maybe I should try them again. I've loaded 90gr gmx, 90gr blitzkings, 100gr interlocks, 115 vlds and 115 bt, the 115s by far shot the best. I'm guessing because of bullet to bore alignment in the long Weatherby throat.
Lol ballistic tips are flying bombs and awesome. Generally they flatten deer with authority!
