Actually, those numbers are also on Youtube independently tested by guys like us. They are even in a 24" barrel where most magnum loads are factored in a 26" barrel. I am just using Hornady's information. How is that "cherry picking"? The 270's 130grain matches up to the 30 caliber's 150 grain in hunting and in print by most all manufacturer and are one of the most popular weights for the same size game.
270 130 grain bullet ='s Ballistic Coefficient .460
270 150 grain bullet ='s Ballistic Coefficient .462
30-06 150 grain bullet ='s Ballistic Coefficient .415
30-06 165 grain bullet ='s Ballistic Coefficient .447
30-06 180 grain bullet ='s Ballistic Coefficient .480
To get a good bullet coefficient in the 30-06 it needs to be using a 180 grain bullet and the its performance looks like this...
30-06
Test Barrel (24") Velocity (fps) / Energy (ft-lbs)
at 500 yards 1751/1225. Drop is -51.30
Point being that the both the 06 and 270 are interchangeable but the 270 has a longer effective range and that's why JOC preferred it. Where one might be slightly better in one area the other is better in another area. Its a wash in shooting under 300 yards. The Hornady Superformance loads has changed the game for the non magnum calibers and pushed them up to new performance bar. I think its great. I see Remington is doing the same but their loads are testing considerably slower than Hornadys.
Coming from 15 years with the 300 Win Mag, its forte was the 180grain bullet and that's also the best ballistic coefficient for the caliber. It just required ALOT more powder/recoil than the 06 to get it to shoot as flat as the 270 out at the 500 yard mark.
Its speed and energy looks like this. 1935/1525 with a trajectory of -41.60.
Still this is closer in performance to the 270 than the 30-06.
This was one of the reasons when coming from my 300 win mag to the 270. Its drop rate that I was use to with the 300 win was about dead balls even with the 270 even without using Superformance.
