thanks for the link , I would have never known that a 30-06 had more power than a 300win mag what a joke , and they list the 30-06 over the 7mm rem mag, and the 300 Wby mag. and the 300H&H didn't even make the list and no 270win but they put the 44mag on the list I shoot a lot of 44mag and 270win , there is no way a 44mag will do more than a 270win, or a 300win mag , I think the USDA had some misinformed 30-06 fanboys working on this and yes USDA Forest services not the DNR !
I just left Prudhoe Bay AK and over the year of rotations, had a lot of discussions with Alaskans who have shot BIG browns.
I read the study in question and will say this.
Some of the more powerful rounds tested ranked lower due to excesive fragmentation and loss of penetration.
Also a criteria was what forest workers could handle recoil-wise if they weren't big or firearms experienced.
.30-06 was ranked highly for being managable by smaller less experienced shooters recoil-wise,
Being available in pump, or semi,
Having greater magazine capacity,
Getting the job done with the right bullet.
Brown's skull is thick and sloped and rounds you'd think will do well just won't penetrate.
For one of these guys, he shot an 800 lb brown charging with a .416 Rigby in the chest with no stop.
The third round was just above the left eye and she fell about 8 feet from him.
I watched the video his girlfriend shot.
Hyperventilating to say the least.
Oh, the first shot was to scare her away.
His CZ holds 3 rounds.
He hunts browns every year and said a lot of newer calibers weren't on the list from 1983, but smaller faster bullets won't stop a big grizzly as fast or as well.
YMMV
