Copper Mono Success on Big Game

It seems like we have a _______ success on big game thread for most every caliber, but I am interested in a success thread for copper monos of any caliber/cartridge.

I am interested more and more in shooting copper. I went hunting with a 308 shooting 130ttsx at 3025fps with the idea of keeping shots under 300 yards but haven't been able to connect yet.

So please share any success photos or stories you have when shooting monos on big game.

Thanks!
 
Took a cow elk at 340ish yards with a 300 win mag shooting Barnes 165 TTSX. High lung on the first shot sent shock waves through her I could see in my scope. She staggered and I put one mid body to try and stop her. Next follow up hit her while she was falling down. All 3 passed through. Whole ordeal was about 10 seconds and she died 5 ft from where she stood for the 1st shot. I'm pretty sure shots 2 and 3 were just me keeping busy until she fell.
 
280 AI with 150 grain Stone Hammers has taken three Afognak elk. From 150 to 280 yards. Two fell within steps of where they were, the big bull walked about 50 yards. Pass throughs on the first two, the shank here recovered from the big bull. High lung shot there. Petals did their jobs on the vitals of all three.

Also several Kodiak black tailed deer with 6.5 CM and 124 grain Hammer Hunters. No fragments recovered from them. Generally 100-200 yard shots, and fell within feet.

I have had exceptional success with 308 150 gr trophy copper and 130 TTSX, and 6.8 SPC 95 TTSX over the years at ranges up to 250 yards on eastern whitetail. 3 large bodied bucks in particular stand out in my memory as they all dropped like struck by lightning. One did a backflip and fell dead. I shot a hand loaded 130 TTSX that sheared the top of a buck’s heart at 240 yards last weekend and he was found 10 yds away.

ETA- like OP’s, my 130 TTSX were traveling at 3030 fps out a 20” xbolt.IMG_2245.jpeg

I think a thread like this is a really good idea, but I’d really like to see the same kind of post mortem wound channel, distance and impact velocity documentation that the 223, 22cm, 243/6mm, and 6.5 cm threads have. There has been a lot of development in the mono/non-lead world in the last decade or so, but there hasn’t been much in the way of unbiased documentation of performance. It would be great to see that level of discussion on this topic. We’ve had bits of it hear and there, but it would really help to try to bring it under one roof, so to speak.
 
Certainly not the biggest deer I ever got, but it looks good in the freezer. Forkhorn was taken with a 30-06 175gr LRX over Varget. Accurate load from that stainless Win 70. Quartering toward, 90 yard, hit on point of shoulder, exit through ribs on other side. Nice size holes. Looked about like what conventional SP does. Ran no more than 20 yards. Really more like "a few leaps and fell over". Sorry I don't have any pictures of the insides.

Big doe was a 6.5x55 loaded with a 100gr TTSX over VV N150. High shoulder/spine shot, so of course straight down. Left a nice size exit after going through all the bones involved. About 75 yard.

Next time you kill an elk with these, it would great if you could show us some pictures of what the petals “doing their job” means in terms of tissue damage.
 
I've shot several moose with 160gr TSX froma 7mm Rem Mag, 175gr LRX from a .300WSM, 225gr TSX from a .35 Whelen and 250gr TTSX from a. 375 Ruger as well as deer with 120gr TSX amd 120gr TTSX from a .260 Rem. Pretty much the only bullets have been using for the past 20 years. Sure, it might not be a statistically significant number but I've never lost an animal or had one take more than a few steps. I've never had the impression that they were awful killers.

This was my thinking. I know it's going to start slow because copper gets a lot of pushback on here, but I'll bet the 223 thread took a while to get rolling too.

New projectiles and performance have potential to shift the paradigm. It flies in the face of the popular thinking around here in the small caliber, match bullet success, but it's not that dissimilar.

1- It starts an uphill battle against lore of old bullet technology that wasn't tremendously effective,
2- It shoots lighter bullets than traditional, i.e., 130 grain 308 win, for reduced recoil,
3- More and more people are open to the idea of shooting copper if it works.

I'm genuinely curious as to the effectiveness of the variety of copper bullets. I'd love to see the same level of necropsy evidence as the 223 thread. I'm hoping to contribute my own, soon.

If I have the chance I will. I hope that with an elk down on Afognak Island I can be forgiven for thinking of photos last. There’s toothy big furries to think about.

As a description, we basically poured the lungs out of the first two elk. The lungs were essentially liquified. They were at 125 and 150 yards. With the terminal performance I’ve experienced, and with the ease of working up loads, I always go to Hammer bullets first. I’ve used Barnes and had no complaints with those either.

I’ve had great results with .338 160 and 185 TTSXs. Haven’t had to track an animal yet. Though all have been <~200yds. Internals were soup. 160s start at ~3000, similar to your 130s.
Those 130s should work fantastically.
 
I don't have any experience with monos yet. I will be working with them in my 30-06. Monos are going to catch on IF the alloy cases take off. We should be able to push heavier bullets faster in the same cartridge that we use now. There will not be as much need to drop bullet weight to achieve reliable velocity for expansion. They just did a podcast on Vortex about the .308 loaded with 130 TTSX.
