6 mm 80 gr TTSX performance ?

[swd]

Wow, that's fantastic.

The Barnes are nothing short of fantastic. Without a doubt the very best killing bullet made today. If you want longer range then check out their new LRX bullets with the VLD design. The BC is actually stated higher for a 175gr LRX than a 175 Berger VLD. I can tell you that when I switched to the LRX from a 168 VLD Berger that point of impact was identical at 300 yds. Never moved the scope a click, no change. What did change was the terminal performance.

As long as it above the expansion minimum, you will be good to go

10-1/2 years. Not a record, but it's up there.

Some amazing stories here. I have been hunting deer for well over 40 years and have kill them with everything from a 22 to a 300 RUM witch I us to this day. All my rifles have been trued with custom barrels I hand load for each and I know the limits of each and my abilities of shooting them and am not going to take a knife to a gun fight, so if you have bigger that will do better use it. I do be leave in a humane kill. Most of my shots will be over 200 up to 400 and in the neck for a sure kill or a miss and not bragging I don’t miss often. Bigger is better at that range.

Hi Changeling, not quite sure what you are looking for in this thread, but the 80 grain Barnes TTSX is absolute death on whitetails especially when driven hard. My son who just turned 15 is going to run his model 7 in .243 here in Pa. again in 3 days which has original walnut stock and has been bedded/built by my local smith and sports a 22 inch finished Rock Creek SS barrel with 10 twist with a full action workover and we are pretty much limited to maybe 90-95 grain max bullet wise. He has shot 5 deer in last 4 years with 5 Barnes 80 grain TTSX bullets pushed by the current load of IMR 4064. .274 match chamber and I'm turning the necks on the Nosler brass for his rifle to a loaded diameter of .269 . That's his bragging rights at school: "My dad uses custom Nosler brass and turns the case necks on my deer rifle" This rifle is a hammer and 4 years ago i started my son out with reduced loads shooting same bullet in same rifle with H4895 load recipe courtesy of a fellow member here on 6BR. Last year and now again this year we have bumped the powder charge up to adult standards. I wonder why i even bring my rifle with me. ;D But thats what its all about is ensuring you friends or family have a nice piece of equipment and deliver the kill shot when and where it needs to be. I believe what I see and seeing is believing.. Nothing better to sit back and enjoy the show. As to OP's post the 80 grain TTSX at semi long range will kill whitetail. But upon thinking on my 43 years of deer hunting my longest kill was around 225 yards. And that was when I was young and never reloaded. Now I prep my rounds for my son and I like I do my 1000 yard BR rifles and it payed off last year as my son rolled his big doe at over 200 yards running. The Barnes TTSX bullets simply kill better and faster then any bullet i have played with. I do not talk about ft. pounds, energy or distance etc. It's all about knowing your load and your rifle.

Frank , this is and old post but still true. Frank , your son and you will never ever FORGET,
THIS QUALITY TIME , Buck , in n.c.

Someone , needs to write a book about "these hunting times" I just thought I was a deer hunter.

A few years ago, I hit a blacktail at 297 yards with an 80gr TTSX from my 6mmDTI. Muzzle velocity 2950fps, impact velocity 2250 fps. It was trotting quartering away, impact entered right lung, transvered the torso diagonally severing the spine in the lower neck, and came to rest under the skin on the left neck. The buck dropped instantly. Perfect shot, perfect performance.

 

[DiRTY DOG]

My 243 shot these at 3400fps, expect the same performance as above out to 450 yards in a 243, with a max effective range of 500-550 yards.

WORKS WELL FOR ME OUT OF MY MODEL 7 243 W/H-414

What velocity on target would you be left with at 400 to 500 yards? Around 500 Yards I may be a bit uncomfortable regarding optimal expansion at the lower velocity on target at the longer distance. Would my concern be proving un-founded?

 

[Gary in MD]

Old thread but I’ve shot the 80 TTSX out of my 240 wby some in the last two years. Killed a couple of good sized white tail does but they were under 150 yards so not much to report there. I did shoot a red fox at about 385 yards. The bullet did expand well on the small framed fox and left an 1 1/2” exit wound through the off shoulder. Muzzle velocity was a little over 3700 fps.

My rifle has a 20” barrel leaving at bout 3250 so at 400 2600 to 2700fps but it would still expand just fine I would think

It's less about energy and more about retained velocity. Your question should be whether or not the bullet is moving fast enough to expand at 400-500 yds. Opinions will vari, but my opinion is that Barnes uses a relatively hard alloy in their rifle bullets and I don't trust them to expand if they have an impact velocity below 2000 fps. IF it's moving fast enough to expand, then the monolithic projectile will likely retain enough momentum to also provide good penetration.

If the bullet doesn't expand and instead just pencils through, the animal will still die from a shot to the vitals. Its just a question of how long it takes to die, and what kind of blood trail it will leave for you to follow.

One of my favorite things about monolithic projectiles is that on the rare occasion you can recover one, they look just like they do in the advertisements where as a cup & core bullet is normally a mangled mess that looks nothing like the advertised mushroomed picture of itself.

My 243W load with 8208xbr was 3460 fps, which drops to 2000 fps at 570 yards. That's a hot load.

You should expect a regular 243W to be effective to 500 yards and 2000 fps. Probably better to keep it under 450 yards for an impact velocity of 2200 fps. Plenty far.
