PDub, the factory COAL for 340 225ttsx is 3.640.

I swear by the 225gr TSX in my .340 WBY. My main load is with 86 grains of AR2213sc (Aussie powder) which is the same as H4831. I have also used 86 grains of RE19. My COAL is 3.700" with constant 1.00" or less groups. Velocity is right at 3000 fps. 
I have used it with great success on Water buffalo, Banteng, Scrub bulls and pigs here in Australia. Plus Lion, lioness and assorted African plains game. I have found the 225gr TSX a much better performer than the 225gr TTSX and 250gr TSX on big game like water buffalo and scrub bulls.
My rifle did not like the 225gr TTSX with groups averaging 1.5" or greater.

What was the main performance difference between the TSX and the TTSX, besides group size.
I ask because the bull in my avatar was taken with the 225 TTSX bullet. But that was one shot and one set of conditions. You have taken several large frame animals with these bullets. Interested in your findings

I found that the 225gr TTSX opened up to fast on the big critters I shoot. It would be great on the smaller thin skinned game like your Elk, deer and African plains game.
I just sold my 2 boxes of the 225gr TTSX to a mate that has some feral horses he needs to cull. They would be perfect for that size animal from any distance.
Then with the 225gr TSX I feel it doesn't open as fast and penetrates deeper than the TTSX on things like our water buffalo, banteng and scrub bulls that have thick hides and heavy bones.
I have only shot a couple of small buffalo with my .340 and if I was to hunt a big old bruiser of a animal I may step it up to the 250gr TSX.
I took that Lion in my avatar using the 225gr TSX. Hit him with two frontal chest shots at around 50 yards.He was dead on his feet after the 1st shot but hit him again to be sure. We recovered both projectiles under the skin of his back legs. They had blown all the petals of but had shattered one shoulder and caused a complete mess of his insides! Couldn't tell what was what in there lol

Thanks for the info. You cant ask for more than what that bullet and caliber did on your Lion. That must have been very intense moments.

The 225 grain TTSX shot out of a 338 win mag took that elk in the shoulder as he was quartering toward me at 380 yards. Found the bullet just under the skin by the last rib on the off side. After cleaning it up, it weights 227 grains, there is a bone chip under one of the pedals. He never took a step

Thanks again for the info, it is always good to get other people's experiences so you can make an informed decision on bullet weight and type in the future

Yes Mike you sure are right it was intense. I have had great hunting success with the 225gr TSX in my .340. If I could only have one rifle that would be it.
One of my favourite trophies is this nice bantang I took. He was side on no more than 30-40 yards away. That blood down his side is the entry wound and the exit was twice the size. He only ran 20 yards or so and piled up. The blood he spurted out was amazing! I'd never seen a blood trail so big before.
Yep it's fair to say I am in love with my .340 and the 225gr TSX  :-*  ;D

I'll second the idea that if you're getting two together and one flyer, your best option is to adjust seating depth. And my suggestion is to go shorter, incrementally, until the group tightens.

I've had excellent success in my Weatherbys with IMR7828ssc, by the way. Good luck with your load developmemt.

Thanks for the input guys, played around with seating depth and not much success. Had access to a crony and was rather disappointed with my velocity, so i'm going to "up" the load velocity and try again. One group with 2 shots through the same hole only gave me 2870fps, and to be honest, i was hopping to settle on something at least 3000fps. If it's not there, i'll take what shoots good and live with it.

Thx for the COAL BlackBear3. I actually did a ladder test with the 225g TTSX after i became frustrated with my results on the 225g TSX. Good comments on the TSX BB340. I'd be just as happy if only i could get my 340 to shoot.
Very interesting ladder test. I don't do these very often, but was confused with the results. My regular loads don't shoot this well. WTF???

Have a look:
-IMR 7828
-GM215M primers
-225g TTSX
-COAL of 3.740" (took lands at 4.113" and subtracted freebore of 0.373" for 340 wby)
Loaded the following charges:
-89.5
-90
-90.5
-91
-91.5
-92
-92.5
-93

Bullet impacts labeled with charge weight. No pressure signs throughout test. Wish my groups were as good as the 4 different charge weights...

So... what do you make of this?

Having loaded Barnes bullets in numerous calibers, my best were always at their manuals suggested length and about midway on their loads. Having taken a 200lb. hog at 40 yards and observing the Barnes bullets performance on a tough animal at high velocity, I have ZERO questions on performance!  :D

Based on your ladder, I'd consider building 6rds at 90.5gr and see how they group. Any idea what your velocities were for these? Because you're going to want a pretty consistent velocity (which it appears you have in the 90-91gr range, based on the group precision) to ensure good groups across ranges and conditions.

Hey Dubyam, I didnt see any pressure signs at 93g. What do you think of conducting a ladder test from 93g, moving upward in charge weight?

No. You're already 2gr above book max from Barnes, and as far as I know, you don't know velocity on this ladder, which means you have very little on which to base your pressure assumptions. With pressure, no sign has to include a velocity measurement. Without it, what you're saying is your brass case integrity is high, and nothing more.

If you were at 89gr, I'd tell you to work up to the book max. I'd also admonish you to chrono the loads as it's the single measurable quantity which is directly demonstrative of pressure.

The ladder you ran gave you a node at acceptable, tested charge weights. Use it.

Thanks dubyam, good advice.

I'll work on that 90.5g charge and see what comes out of that.
