.340 Weatherby

I have a .340 weatherby mag and was thinking about using it on an upcoming elk hunt this year. Anyone have some pet loads and what powders work good? Not sure which bullet I want to use yet either..... Any suggestions?

Thanks

Very good with 250 Sierra boattail and RL25 for a velocity of 2930.

80 grains of Rl 22 or 74 grains of H4350 are good powders and I would recomend the 250 grain
Partitions are great for larger animals.

77gr of VIT N550 with 210 gr Barnes TSX. If you want to go with 225gr bullets, 89gr of IMR 7828SSC with Barnes 225gr TSX bullet.

Kind of obvious I'm a huge Barnes Bullet fan.

Re: .340 Weatherby

Great choice! The 340 wby is one of the best elk cartridges ever built. Over the past ten years we now have more choices with the lapua and ultramag cases and the 338-378 wby. But up until then the 340 wby was the man. The lapua and ultramag cases only get you maybe 150 fps over the 340 which to an elk doesn't really make any difference. I have shot a number of long range elk with the 250 sierra game king and the 340 when that bullet first came out in the 70's as the highest bc hunting bullet made at the time. My load of 7828 gets 3056 fps. Now I am playing with the new barnes 185 ttsx .432 bc at around 3400 fps. It is flat shooting and does a great job in the 340. I had a great load with the 225 AB and 7828 in the 3200's but quit using the 225 AB because of continuous bullet failure. All of the bullets and loads mentioned in the thread are great on elk and you will enjoy hunting with any of them. The 340 is just a great elk rifle.

LTLR:

How's the 185 grainers performance on game? I thought this would be the ideal round for deer/elk sized game when paired with the Barnes bullet but have been told that it was too light for the caliber at the velocities the 340 cases would push.

At 3400 fps, you are pushing a 338 caliber bullet as fast as a 240 Wby factory load. MPBR has got to be close to 350 yards.

Re: .340 Weatherby

LTLR, My .340 loves the 250gr Nosler Partition factory load, but I have had such good performance from the Accubonds in other calibers, that I was ready to spring for a box of the 225gr .338 cal AB's to try in it. You mentioned consistent bullet failures with this bullet. It sounds like the nature of the failures is poor terminal performance.

I haven't bought the bullets yet.

Thanks, Tom
