If you reload it won't be bad but neither will a 300 rum or a 338 rum.
Look into the ballistics for a 300 rum next to the 340 wby.
Yes completely different caliber but with the 300 rum with a 180 gr bullet well out performs the 340 wby with a 225 gr bullet both in velocity and ft.lb. energy. My neighbor and I just went through this exact conversation a couple of weeks ago. He was dead set in his ways for a 340 wby but after I showed him how the 300 rum performed he agreed the 340 wby would be a pore choice and ended up buying a Sendero 300 rum.
Just my .02
If you have never been overly impressed by the 340 it is because you have never used one.
Paper ballistics are great, but they give no credit to bullet size nor the much heavier construction of the 338 bullet. On large game at normal hunting distances the cartridge is a legendary performer whose bone smashing bullets leave any 30 cal behind in the dust. I have killed Alaska/Yukon moose, grizzly, black bear, elk, bison, kudu, eland and a host of smaller animals with the 340...I can assure you it preforms like no 30 cal can when the going gets tough. The tougher the shot angle and the bigger the animal the better the 340 looks...I spent 10 years killing animals all over the globe with the cartridge.....I am not guessing about this.
At long range "flat shooting" means nothing...I dial up for the drop.
So what if we compare your 180gr Accubond at 3400fps to the 340Wby with a 300gr Berger @ 2500fps? At 600 yards the 300UM retains 2261fps/2043ftlbs while the 340Wby is 1912fps/2437ftlbs? Better yet in a 10mph crosswind the 340 only drifts 18 inches while the "almighty" 300UM drifts 21! By 1000 yards the 340 has almost caught the small bullet in velocity and has 600ftlbs more than your 300?
Yes, I picked the best bullet for the 340, but you stacked 180 grains in a ridiculously huge case against it. Is a 300 a great choice for the lower 48? Absolutely! I might add the 300Win is my favorite.
That said the 340Wby is hardly a poor choice anywhere on this planet.
