.340 Weatherby

[Long Time Long Ranger]

Haven't shot anything yet with a 185. Just working up some loads. The barnes will not come apart though so I am confident it will be fine. Faster powders like 4350 and similar are better with the 185. One load of re 19 got well into the 3400's. My barrel is a douglas xx supreme 28" 1-10 twist. I have shot a 100 grain tsx out of a 257 wby through caribou, elk, and other critters with excellent performance so I feel good about a 185 grain 338 bullet. I will let you know for sure during hunting season. May pop a grizzly with one in August.

Tom, I used the 225 AB for the first time last year when I switched over several rifles to it. Some of my friends I did 338-300 ultras for did also. I really liked the velocity/BC ratio and the accuracy of that bullet is excellent. I put three through the chest of a big 6x6 bull elk and every one were complete jacket seperation/fragmentation bullet failure. My friends experienced the same thing. I have several boxes for sale cheap. I spent a lot to work up loads in my rifles last year and changing again this year.

I have a .340wby as well as my father. We shoot Barnes exclusively in them. We've gone with the 225's because they shoot so well. We're now using the 225 TTSX. My load is 86 gr of RL 19 and my fathers is 90 grs of RL 19. We probably need to try another powder but this combo shoots so well we haven't bothered. My load is pretty mild but you'll want to work up to the 90grs. It's hot but not over pressure in his gun. It is in mine but mine is built off a Rem 700. Have fun.

LTLR, from your observation, do you think they might work at .338 Win Mag. or .338-06 velocities? That might be an outlet for you to sell them. After the .340, I thought I might try a few in .338 x .378. Your experience will save me from trying them in either rifle.

Boman, sounds like the 225 TTSX's would be worth trying. Question, does your dad's rifle and yours both have factory dimension chambers? (plenty of freebore).

The 225 accubond is an extremely accurate bullet. One of the best I have ever shot. It does very well in my 338 winchester, 338-06 imp and 338 Gibbs. In the big 338's it gets very fragile from what I have seen.

specweldtom,

Yes they both do. Dad's is a factory Weatherby Accumark and mine is a custom off a Rem 700 action with the factory freebore specs. I've shot hot loads over max in mine but I get just as great accuracy by dropping down a few so I've just gone that route. Dad's seems to only shoot well at max pressure.

I have a Mark V in 340 with a 26" Douglas supreme XX 1-10 twist with Weatherby freebore. I have had great results with the 225 TTSX. I had good results with 7828 but i had great results with H1000 and it is much cleaner burning.

Ovastafford, you asked the question, but we both got some good, real world info.

Good thread, thanks to all. Tom
