Not directed at you, just generally speaking. It got comical.
I believe you and your friend. I feel that there are failures in anything mechanical. We will see failure from all sizes of bullets at some time. The value I see from smaller cartridges, is that you can see your impact easier and if you have a failure or a miss your ability to get back on target and send an additional shot. Where I hunt we preach for people to keep shooting until your animal is on the ground not moving or out of sight. I can do it with a 300WM but I'm way better with a 6.5CM and stupid fast with a 243.

Not if hand loading lol. My 21" PRC sends the 143 at 2930

Of course, you can do much more with handloading. I bet if you had a 26" 6.5CM you could run it pretty hot as well. Probably not 2930 hot but still get moving.

My point was more that, a 6.5mm bullet is a 6.5mm bullet. Both 6.5cm and 6.5PRC are the same in a way, one just has more horsepower. Some people will jump on the bandwagon and say you can't kill and elk with a 24" 6.5cm factory 143 but a 20" 6.5prc shooting at 143 will smash the elk. A 6.5prc doesn't make an 143eldm a better bullet, a 6.5cm shooting the same bullet will do the same damage at the same velocity.

Know your bullet, know your velocities. Figure out your kill ranges.

My 24" 6.5CM with the 147 ELDM is 2599 fps and my 22" 6.5 PRC with the 147 ELDM is 2830 fps. Even if I lost 100 fps going from 22" to 20", I'd still be 130 fps faster than the 24" 6.5CM. This is with factory Hornady ammo. With handloads, you can push the 6.5 PRC far harder than the 6.5CM.

True. I had a S20 sako in 6.5 prc I sold, kind i regret, just such a well made rifle, but it wasn’t giving me super impressive results with factory ammo

I've only had 3 bullets fail to reach vitals that I can think of from my hunting experience, and none were suprising failures given the bullets used and impact velocities and locations on the animal.

  1. 180 factory Core-Lokt from a 300 WM. Shot an average sized black bear sow at 17 yards, so impact velocity should have been right around 3k fps. Hit was high and back. Broke spine but bullet "splashed" on impact and left about an 8" (grapefruit sized) crater in the side of the bear. Wound was 6" deep and 6-8" wide. Bear ran into thick brush only 10 yds away, we didn't want to deal with a wounded bear in that brush, came back in the morning and found her dead right where she had entered the brush.
  2. 145 ELDX factory precision hunter from a 270 Win. Mule deer buck at 20 yds. First shot at 60 yds was a liver shot and buck headed into the scrub oak. I later found that the rifle had lost zero. When I caught up to him, he was at 20 yds facing straight away. Shot him right at the top ball joint of the femur. Bullet entered 2" and rapidly expanded leaving a 6" mess of broken femur bone shards and muscle tissue destruction. Buck dropped at the shot but bullet failed to penetrate past the leg muscle, so I had to put another finishing shot in the vitals.
  3. 147 ELDM from 6.5 PRC. Cow elk at 430 yds. Poor wind call and hit the elk in the middle of the femur. Bullet broke femur completely in half and penetrated another couple inches of leg muscle but failed to penetrate beyond the onside leg muscle. Second shot was directly behind the shoulder, she traveled 20 yds downhill and crashed.
Based on my experiences, If 6.5 and .277 match projectiles can completely break a mule deer and cow elk femur in half and penetrate a couple inches after that, there is no logical explanation to a shoulder blade stopping these bullets except for a failure in construction of the bullet or very extreme impact velocities (3500+ fps) outside the normal use case the bullets are designed for.

Thanks this was the best write up so far… even if there weren’t pictures haha

I really need to get better about taking pictures while breaking down animals, but it's usually pretty low on the list of priorities with an animal on the ground and bloody hands to think about pulling my phone out of my pocket. I'm not glad about having the data from the femur shots, as obviously it means something went sideways during the kill, but I feel that it's useful data to share.

It's not gun-related but I did have a broadhead fail to penetrate an elk shoulder. It was the old-style 3 blade 125 gr ramcat. It was a raghorn bull at 33 yds and a medium weight (530 gr) arrow out of a 72# bow. The bull was standing over a log and the impact sounded so solid, I thought I missed low and hit the log. It actually popped the nock out the back of the arrow at impact, and when the bull whirled, the arrow was only sticking a couple inches into the shoulder. Never found my arrow or the bull and there was only a few drops of muscle-looking blood at the shot location.

I’m with you man, I’m 100% of the time focused on cutting my animal up and getting ready for haul out, not playing forensic scientist, but it is good knowledge for sure. Your observations were very believable in a physics sort of way and I appreciate that not just cause it reinforced a bias, but I do think we often are really bad at spotting hits or remembering what happened. I totally think you could have a broadhead fail if you hit near the knuckle, especially if it’s not a super solid head, arrows can do weirder things than bullets sometimes IMO. Thanks for sharing!

When you all say “shoulder” do you mean a joint like where the top of a humerus ie “leg bone” meets the scapula, or are you referring to a scapula itself ie “shoulder blade”?

Seems like those are very different thickness bones, so just wondering.

Glad you were able to get some information from it. I have an engineering background and am naturally a pretty logical and emotionless person (much to the dismay of my wife), so I try to stick to the data and facts most of the time. :ROFLMAO:

So do we have any real hard evidence? We have eld-X shoulder guy’s friend and then some weird metric of full pass through vs no pass through then lots of talk of marginal shots or no animal or what not…. Seems like we don’t have a growing body of evidence for these failures…
It hasn’t gotten talked about much on this thread but the .223 kill thread has lots of discussion regarding non-tipped match bullets failing to expand. My uncle had this happen multiple times with his AR on pigs as well. So at least thats a type of bullet failure that we all seem to agree does happen.

Good post I kind of took for granted that shooting the non tipped match in .223 at game wasn’t a great idea, I thought it was kind of a known thing. Only ever used 75 grn blacks on coyotes .223 isn’t legal in Co for big game and its worked fine

Since there seem to be no failures I might as well go off topic...
I only made it half way through and then skipped to the end. But, I think it's worth mentioning that it sure looks like the 77tmk's kill things quicker than old fashioned high weight retention bullets. In my experience blood trails are hard to see, especially at night, so a quicker death may be more advantageous than a blood trail. I don't like atomized lead in my meat or the scavengers so I shoot warp speed 22CM monos that shed petals, and they seem to travel about 100 yards and die pretty fast. I guess if they were getting lost in thick vegetation I'd go up in caliber. FWIW

I literally relayed a first hand situation with pictures that showed a deer shoulder with a wound where 99% of hunters aim, a peeled back jacket and deformed lead core, internal pictures of a cavity with a ton of bloodshot and no penetrations. I got told my friend is lying, people that aren't Delta Force or SEAL team don't actually remember what they did, those aren't pictures of the same deer and he's after personal gain, he didn't see another deer in front of the one he shot perfectly where he was aiming, etc.

You can't make that shit up. It appears no amount of evidence or attestation will appease the cult, if you're not there, it doesn't matter.
I’m not in the small caliber camp, but I gotta say I am scratching my head how that situation could have physically occurred. There was a mass of a bullet left (vs it somehow truly blowing up) that somehow was stopped in a very short distance against tissue and thin bone, I don’t understand what the mechanism of failure could have been. A explosive bullet at full speed would destroy more tissue and have less retained mass right? Would a squib load going slow have deformed that much?

@Harvey_NW I think I have the mystery figured out! This buck had been shot before but that bullet was stopped by the impenetrable shoulder of a blacktail deer. Your friend just happened to make the perfect shot, which hit that bullet and tear open a nasty wound while ricocheting off into the woods where it got stuck in an old growth log. That bullet will be found by the next generation of loggers and be the story for the ages of the bullet that stopped the resaw line.

Case closed! 😉😆

Is that superlite really a1:11 twist for a 6.5prc?
I wouldn't think so. Every 6.5 barrel I've seen in a Tikka was 1 in 8". I'm getting no response from anyone about these Sports South special rifles on if the 300WSM is a 1 in 11" or a 1 on 10" as nobody has them in stock cause they are all getting drop shipped from the warehouse.

Re pass thru’s.
A barnes with a huge frontal area often stops under the hide on the far side. Not so often ime on deer, but have seen this on a couple elk out of a small total # of elk kills.

Theres lots of info on what it takes to get more penetration out of a frangible bullet—it takes a heavier bullet relative to the caliber. So a 77gr .224 or a 108gr 6mm will probably penetrate deeper than a 130 gr .308. I cant help with quantifying that, but that’s ^^ been discussed ad nauseum here.
Agreed on the discussion re: penetration being ad nauseaum! But what I'm asking is:

Is there any actual testing or large sample-size documented field data showing differences between various bullets at various calibers in terms of ability to reliably create exit wounds for better tracking and blood trails? The kind of data I'm looking for and which I think would help settle this discussion would be a listing of a bullet at x caliber and velocity with average penetration depth on valid gel.

For example, a series of gel tests that results in the following type of data set:

Hornady ELDX, 6mm, 2500 fps impact, average penetration 15"
Hornady ELDX, 6.5mm, 2400 fps impact, average penetration 6"
Hornady ELDX, 7mm, 2300 fps impact, average penetration 18"
Hornady ELDX, .308, 2200 fps impact, average penetration 20"

(these numbers are totally fabricated,, this is just an example!) In a perfect world this would be extended to include various impact velocities as well and would also include average volume of permanent wound cavity. (or at least z" x y") Then one could choose caliber and bullet based on one's own desire to balance larger permanent wound cavity creation with more reliable exiting.

One possible way to start to assemble real data would be to go thorough the .223/.243 pages and document number of exits versus non exits. That would probably give us pretty darn reliable data about the various small/ frangible loads and their average ability to penetrate through ungulates. Maybe in my spare time!

I do get that at some point this is just gun geeking for gun geekings sake and what we all need to be doing is doing field simulation practice at the range and shooting more animals! Having said that I gotta go to the range!

.50 cal Muzzleloader with powerbelt 220gr bullets leave no blood or a shitty blood trail. 😅
I don't have the patience to dig for what you replied to:

Have you ever shot a deer, or know of someone else shooting a deer with a larger caliber that also didn’t leave blood?

But yeah, I can point to (at least one) a thin-skinned mature eastern NC whitetail shot well and behind the shoulder at about 20 yards with what I recall was a 7x57 Mauser 139 gr. Corelokt. He went about 30 or maybe 40 yards before leaving a speck of blood. I tracked him by his hoofprints to that point and found him dead as a hammer by a bloodtrail that began at that point to about 70 yards.

I love muzzleloading, but have always steered clear ot the Powerbelts. Never have heard much good about them in my circle ---

Hammer and in-line shooter here.
