The 180 gr copper bullets start being borderline fast enough past 500 yards. The 200 AB is still above 1800 fps to almost 800 yards. I still think the 200 AB is the best all around choice.
It probably is the most versatile option, you're right. It's a great choice, for sure. It most certainly will do it.
If we are stipulating 800 yards, it's the winner. Should probably be looking at the 210 LRAB then too. And the 300 RUM.
Looks like the Barnes offering in 200gr is either TSX or LRX, not TTSX. The BC on the LRX is .546 vs 200gr Accubond is .588. The 200gr LRX loaded appropriately is going to be good to at least 500 yards. I still like the 200gr LRX (changing my answer) inside 500 yards which is where most people are hunting. For moose and griz, I'll take the Barnes and get closer if I have to.
Assuming where most people hunt, which is inside 350 yards, the Accubond takes the backseat to any 200gr Barnes bullet in my opinion (when it comes to Moose and Griz and quartering bull elk). Both bullets would do the trick though.
No way would I step down to 165gr in monolithic or 180gr in accubond, not because it wouldn't work, but because the cartridge is capable of flinging the heavies and the extra weight and BC are worth the recoil. And you're gonna put a brake on it anyway, if you're gonna shoot it enough to be confident at 800 yards.
