I have used the 250 Std Speer on big bodied Bull Moose 3 and have yet 2 recover a bullet 2450 FPS. Used the Std 250 Speer on a 6' Black Bear this Fall with a 35 Whln. Imp. 2580 FPS. Penetrated neck & out heart. Would not be concerned using either rifle with either the Nosler Part 250 or Speer GS older style or older 250 Speer Std. on big bear. Bullet placement is everything.
