.270win 130gr@3200fps = 2956fpe :sok2
.308 165gr @2880fps = 3039fpe :sok2
30-06 180gr @2880fps = 3315fpe :sok2

I've never seen a factory catalog post numbers this high before.

Is this just hype or do these federal loads really carry this much more potential energy? We all hear the hype from Hornady's superformance super speed ammo, but even they don't claim energy numbers this high :confused: I think Hornady just sparked a new muscle car war and I like it!
 
The .270 doesn't seem too far off the mark since the original velocity was supposed to be 3150.
The .30-06/165 is only 80 fps faster than normal so that seems do-able too.

The .30-06/180 @ 2880 is way beyond what I can get out of my own handloads.
 
IIRC Why Not? was hitting 3000ft-lbs of energy with RL17 and the .308 Win. And that was based on velocities measured by an Oehler 35P, as opposed to a manufacturer's claim.
 
RL17 and N550 seem to be giving big numbers in the 308. We will have to see how things continue when it warms up and guy hit the range. The numbers look promising though.
 
Is RL17 good for someone looking to shoot exclusively 150gr SP and monolithic copper bullets, or is it a heavy pills only powder?
 
Why Not was cooking up a load with enough energy from the 308 for a young lady to legally hunt bison in the Yukon. IIRC he was using a 150 or 165gr bullet. Hopefully he pops in here. So no, it's not just for the 208 AMax, though it apparently makes those things move like Jagger.

Too bad that energy doesn't mean much in terms of terminal performance on game, where as velocity does have an effect on trajectory. Consider any two bullets of equal caliber and weight, one a soft point having a thin jacket and the other a mono-metal solid. Provided the impact velocity is the same, the effect on tissue will be much different despite identical energy. A chronograph will tell you quickly enough if the numbers are real or hype, although because chronographs are so easily acquired now, it does seem unlikely that an ammo manufacturer would intentionally fudge their numbers. New propellents historically have boosted velocities.
 
The R-17 and the 208 Amax in my Nemesis 308 were quite incredible both in accuracy and power, i did back down from that recipe for summertime, ( one gr over max, i not recomendable ) out of the 20 inch tube, over the Oehler P-35 i was pushing those 208 gr @ 2600+ fps, what equate in energy @ 3100 pounds of energy (...WOW for 308 ), since that time i have found out the superiority of the Scenar ogive 155 gr but still use R-15 in my pet load, over 178 gr R-17 is king... JP.
 
From my notes, for a 30-06 Husqvarna, velocity taken with a Oehler 33.

xx grains-- Norma 204--Norma 180 grain bullet---Av. 2810 fps--es 11---fp energy 3156.
 
The .270 is only 50 fps more than the 130@ 3150 that made the .270 famous in the first place.

The .308 is a little faster than I have personally ever experienced, say by 80 fps, but I've never pushed my .308's hard since their mostly semi's.

The 30-06 I duplicate exactly with RL-17 and Winchester 180 grain PP; it's actually my standard load lately. I can also push 210 grain Berger VLD's to that same energy level using RL-17. Both of those loads are from 22" bbls too.

So, it sounds like factory ammo that isn't all lawyerized....ABOUT TIME!

Now if they could start producing some European cartridge loads like this in 6.5x55, 8x57, 9.3x57 etc, you'd get me even more excited!
