Are sabots illegal there? The reason I ask is I have a Black Diamond XR and have worked up some excellent loads that I am sure would work on an elk sized animal.

I shoot a 250 or 300 grains Shockwave with 110 grains of Goex FFg. Because of the aero tip on the projectile I think it would get excellent penetration into the animal.

I also shoot some 405 grain Remington SP .458 diameter out of some Knight (orange) sabots and with 90 grains of Goex Ffg I can shoot excellent groups out to 100 yards with them. Because of the flat nose and weight, I think they would also work good.

I do think you might be on the right track with the 348 grain aero tip powerbelts. I think those would work excellent on an elk. Or you could go to the next size up which is the 405 grain if you really wanted to put some weight behind the projectile.

Good luck with your hunt. I will be watching for your updates on it....
