what would your choice be for a grizz or elk hunt as far as caliber. looking to get a big game gun and just thought I'd ask you good'ol boys what you recommend.

If the shots weren't going to be past 250ish, I'd take a .35 Whelen or a .338 Winchester. I'd hunt grizzly and elk with both of those calibers.

If it was me I would take a 375H&H shooting a good 270gr pill

If I were to buy an elk/grizzly gun, I would look at 2 cartridges. The 35 Whelen, and the 9.3x62. Both have similar case capacity, but the 9.3 can push a 286 grain bullet into the 2300-2400 fps range, which should be plenty to handle the big bears and elk under about 250 yards. That also is about as fastas the 35 pushes 250 grain bullets. Only draw back to these two would be there aren't a lot of factory cartridges available, so handloading would most likely be the option to go with. But, they would be able to be had in standard length rifles that aren't going to break the bank too bad and which most people would be able to shoot quite accurately more than other cartridges. Good luck.

.340 Wby. Mag. Good luck.

You opened a can of worms here. I would say something in the .338 caliber range. The new .325 WSM could be an option as well.

338 win mag

Ditto!!!!!! maybe the 338 ultra mag also. That is if your not recoil sensitive

30-06 with 220gr Silvertips and all of the above cals the guys listed.

IMO the list for a goodelk cartirdge is pretty long but since you added grizzly to the mix .338wm would be the min.I would start considering for such a purpose.
