I have found zero real difference in terminal performance at under 200m between the 270 Win, 280Rem, 30-06, 7mm Rem Mag, 300 RSAUM. I tend to use Nosler Partitions, Barnes X and Hornady Interbonds. All animals from White Tail to Moose die if I have put a hole in the heart lungs cavity. Surprise.

My experience with the 300 Weatherby and the Barnes X is pure devastation on game!

Oddly enough I have found the 338 Federal, 338-06 and 35 Whelen to be a step up in killing power. 215-250gr bullets.

Then the 375s seem to be stand alone with the exception of the 9.3x62and 9.3x74r. 286-300 gr bullets.

Same with the forties.

Not much ecperience with anything bigger except the 458 Win Mag using crap ammo, so not a fair comparison.

I agree with a past post, the rifle and scope set up is way more. If I had a fire and lost everything I would probably start and stop with Dorleac M98 in 9.3x62 and a Swarofski 1-8x24 8Xi.
