The best long range rifle is the one you shoot all the time and are comfortable with.  7mag has just the right amount of energy vs. recoil (for me) that I can get performance but shoot it a lot.

Shot elk with 300 win, 338 win always have had broadside shots, just been lucky I guess. All walked or ran off not far but far from a bang flop. But with this utter nonsense of spike bull only in the areas I hunt I switched to a 338 rum. 2 bulls 608 & 676  yards bang flop. 2 cows 550 and 888 yards neither took another step. 225 grain Accubond at 3074 FPS avg. only 1 bullet has been recovered and that the cow at 888. 225 grain bullet retained weight was 189 grain. Shot was quartering toward slightly took at top of shoulder , traveled down blackstrap and stopped just before the hindquarters. Shoot what you want accuracy is final and practice practice practice. Just my two cents. The rum is definitely not deer friendly

Yea the big 338’s are tough to beat for way out shots on big elk IMO.

I love my Browning X-Bolt Stalker Long Range in 30-06 out to 450 yards. If I had to pick one "best" long range cartridge on this list it would be the 7mm no doubt. I won't shoot past 450 yards so for me my aught 6 is the ticket.
