Difference in 270 and 30-06 ammo.

Federal fusion 150G.
Muzzle diff is 50 ft per second/ ft-lbs diff is 134.
500 yards M is 79 ft per second/ 101 ft-lbs
Diff in drop 0@200 is 0.8" at 500 yards

Hornady 150gr Inter Lock SP.
Muzzle diff is 70 ft per second/ 134 ft-lbs
500 yards M is 229 ft per second/ 276 ft-lbs
Diff in drop 0@200 is 4.5" at 500 yards.

So rifle kick is less than a lb if the rifles have the same weight and barrel length. Bullet trajectory averages out to a few inches over 500 yards.

All this information is gathered from the Federal & Hornady reload manuals on line.

Yes the 270 is flatter shooting this round, more so when using the 130's and 140's,,, not in the 165 and 178gr.

I haven't looked at the difference of the 165gr, 175gr and 180gr between 270 & 30-06, maybe this is where the 06 starts its gains in the long range area.

I'll do some sight seeing on Long range hunting and shooting forum too see what I come up with.

Kinda kool to see 4.5" and 0.8" drop between the too groups of bullets Federal and Hornady rounds in 150gr's
