Evan 03 said, "the simple fact is on paper it beats the 270win into the mud. but papaer is no place to be."


No I am known for trashing the "egg-spurts" in the gun rags However, when one does do it right, I'll damn well say so. SHOOTING TIMES, OCTOBER 2005, Page 30, the .270 Win. vs the .270 WSM by Layne Simpson.

On page 33, theere is a velocity comparion between factory and handload between the two cartridges.

.270 Win. .270WSM Difference

" " " factory# (150gr.) 2841 3058 +WSM

* Hornady's light magnum. Winchester's 130 gr. Ballistic Silver tip was 2921 FPS. Winchester's 140 gr. Accubond was 2953 FPS.

# Winchester's 150 gr. Power point.

Based on this, it would seem to me that with either the federal High Energy, Hornady light Magnum or good handloads, you can come close ebough to the WSM specs ans to make the round negligible.
With a proper handload using H-4831, my .270 delivers 3,000 FPS right on the nose with a 150 gr. Nosler partiton. Don't seem worth the extra money yo buy a WSM.
