Home Forums Hunting & Shooting Long Range Hunting Accumark ?

My .340 Wby Accumark is the most accurate rifle I own and can shoot:



Note 378Canuck, if I reloaded, I probably would prefer the .338-378, but for the time, CorBon offers a great .340 load that performs about as well as Wby factory .338-378. I get an average MV out of my Accumark on my chrono of 3,160 fps with the CB 225gr TTSX ammo. I know two others who also exceed 3,150 fps with that ammo. Since I left the military, I don�t shoot out to 800 yds anymore, but assuming the 0.514 B.C. for the 225gr TTSX, it should be moving at 2,432 fps (2,955 ft-lbs) at 400 yds. (I assume you can get higher MV from your .338-378 handloads).

And the rifle easily produces 3/4 MOA groups when I do may part. It might do even better, but I'm not capable of making it do so.

In any event my Accumark and my other Mark-V (.375 Wby DGR) both have been awesome and are my favorite rifles. The unique nine-lug bolt, with its lower bolt lift and shorter bolt throw, IMO make it about as reliable and smooth as a rifle can be.
