You Need to go Over to Longrangehunting .com and ask Kirby Allen or Fifty Driver he has built a Ton of STW's .
Sounds like the wrong bullet for the Twist of the Barrel. He specializes in that kind of Calibers , He makes a smoking 257 STW at 3900 fps.
I appreciate the advise but its shooting very accurate. I don't see how velocity has something to do with twist.
