I'd run one of the Partition loads and not worry about 800 yard accuracy.
Seems like you are making this overly complicated, but folks do that.

I'm with SH on this one. If you achieve your, and your guide's, objective, you will be shooting a 500 lb animal at less than 100 yards. If you are prepared for such an event, it will not require gnat's-hair accuracy on your rifle's part.
I would suggest that you practice shooting at randomly placed targets at random ranges from uncomfortable positions in uncurried country, more than you worry about ekeing the last bit of sub-minute accuracy out of a load combination. Also practice shooting at targets withing 50 feet or so, rapidly -- just in case something does go south.
As far as your rifle and bullet choice goes, I'm not a big fan of Nosler bullets, but others find them quite adequate. If you're comfortable shooting the rifles, either one will work fine.
I'd make sure not to be over-scoped, too.
Mostly, relax and enjoy the adventure.

I'd use whichever rifle I preferred to carry, given your options, and you can't go wrong with NP.

Use whatever gun you are most familar with. Partitions and the 9.3x62 would be my choice, but I'm a Whelen shooter too.
Good luck.

You can do as you please, but I wouldn't take either one of those 30/06 Ackley Improved loads on a hunt of a lifetime.
You are trying to make a 300 Magnum of of an '06 Improved, and if you get up there and have a blown primer or case head seperation at the wrong time, you are going to be hating life.
A 30/06 loaded to normal velocities will do all you need to do and more. the 30/06 AI will give you an extra slight edge, so there is nothing to be gained and a lot to be lost by hotrodding it.
You are focusing on thestuff that doesn't matter, and overlooking what does matter. Think dependability and field shooting skills, not ft lbs of energy parsed to the nearest ounce.

If I were hunting Grizzley for the first time, I would take the advice of those who have experience-and most of those who have replied do-although I don't-to heart. If you don't why ask? That hunt is no place to find attitude isn't enough.

GSSP, if your velocities are above loading manual velocities, your pressures are above loading manual pressures. It's that simple. And if you are running as far above maximum as you claim, you are probably WAY above max pressures.
What I don't understand is why, if you want 300 magnum velocities, yuo just don't buy a 300 magnum?
From your posting of your ultra high velocities and your 800 yard group size, I tend to think the idea behind your post was to impress us with your numbers, rather than to solicit ideas about what would make the most practical bear round.

What do you use to measure pressure?

Royce,
My intent of mentioning the 800 yd accuracy was to head off any questioning remarks of the rifle itself; not to impress. I'm a pretty un assuming guy. I understand what you thought, it's what I meant.
If you're an experienced reloader, you understand that standard 30-06 pressures leave room for more. An example, looking in the 2008 Hodgdon annual, 59700 psi, for the 220 rd nose bullet, is the highest psi I can find for the 30-06. Looking at the other 06 based cases 64000 psi is max for the 270 Win, 100 gr Speer spitzer. That's an increase of 4300 psi. My AI (30-06) case WILL take some extra pressure. So between some extra case capacity, longer barrel, and a few extra thou psi, I know, through decades of my reloading experience, lots of measuring, discussion with experienced reloaders and even some industry experts commenting on some of my loading techniques, I'm doing just fine.
My reason for the Ackley, not that I need to explain it to anyone, is basically a shot out 30-06 barrel, a desire for more velocity without having to retool for a totally new cartridge, less neck trimming and something a bit different.
Please, I don't want to let this get into argument. Let's keep it civil.
Dang, with all those high-powered credentials, I can't imagine why you ask any questions around here.

Any of the above will do fine. Pick the one you want to kill a bear with.
