Yeah it works very well, especially on animals under 100kgs, if you do your part.

Yes Sir. 1977 Winchester model 70 243

Same in Pa, .243 100 grain norma white tail. 1 hit stops em everytime and in short order. 100+ yards.

dont matter what bullet you use. a T800 human combat chassis run and keep running like a deer in a forest fire.

Same in TX with any bullet never had one make it past 30-40 yards unless rhey were running when hit. Most just dropped on the spot.

Hey I’m planning to hunt with 243 this year I’ve got several bullets to chose from I wonder how a 70gr Sierra hpbt will work

@@ThemantleofElijah it will work behind the shoulder. a heavier soft point is less picky about shot placement. they all work

@@jamesyarbrough4777 thank you I recently picked up a 243 brand new Remington 700 with 8 twist I did grab some extra bullets to handload got some 80gr cx Hornady along with interlocks 100gr and then some 108 gr eldm so I have lots to choose from

@@ThemantleofElijah 80 grain cx would be my top pick. super fast and deep penetrating.

@@jamesyarbrough4777 good deal I’m gonna load some up certain on that I was gonna try some Barnes lrx 95 gr but I grabbed these I think they will be some good deer medicine

Excellent read

@@adamwilliams5417 thank-you. she was an amazing human being but ranch women always are

Construction of the Swift Scirocco is perfect for this application.

Aha. You figured it out. Yes, making different cartridges from brass like that can make things confusing. 270 from 30-06, 260 Rem from 308, etc.

Same. Listening to someone else will give a person an expanded view if we keep an open mind.

Right! Hydrostatic shock counts when you hit the heart. I haven't taken many deer but the two I shot with a 243 at 50 yards didn't have discernable hearts which implies something more happened than just a quarter inch hole being bored through the heart. It still all comes down to shot placement and I guess if you miss there is no replacement for displacement.

Thanks Heinrich. That heartbeat theory seems closest to explaining hydroshock. Striek it during its compression stroke and you overwhelm blood vessels in the brain, causing stroke. Some post mortem evidence to support that, too. This likely explains why the vast majority of my heart-shot deer have not collapsed immediately.

Would've been different if you were using a 100 grain nosler partition guaranteed

​@@jamiehurtt3530Facts. Or Fed Fusion.

I've seen similar results, in my 2 cases the rifle had a 18 inch bbl length. On a 243 that overboor to begin with, I think it needs at least a 22 inch bbl to keep the velocity up JMPO, YMMV

@@daye8132 Use the 100 graim nosler partition and you'll never lose another deer with the 243 And shoot straight

SST doing exactly what its designed to do, increase hornadys bank account while selling you a interlock with a platic tip for more money

Humble thanks, Giovanni. Appreciate the support.

Pure poetry 👏 👏

243/6mm cartridges are marketed for smaller shooters and those who are recoil-sensitive. Not everyone can shoot a 140+ grain hunting bullet accurately.

@@bryonslatten3147 Not everyone needs to be hunting big game, either..

@@tacticalmattfoley whitetail isn’t big game.

@@bryonslatten3147 then, 6.5 will be just fine for you and your delicate, effeminate frame....

Sounds great if you also can bleed them while they're down... or if you can close the distance and follow up. Interestingly, I listened to a medical symposium once on handgun wounding trends and ER technology and trauma/surgery success results. A big part of the talk was how they transitioned away from whole blood for transfusions into using separated ingredients to reconstitute a needed blood type from stored ingredients... resulting in ready-to-order large volume transfusions... but there was also talk about how they've seen a huge increase in handgun survivability rates (up to 60% at the time of the talk, perhaps a 10-15 years ago in a major city), and one hypothesis was that the increased stopping rate from expanding bullets also inadvertently increased survivability for any cases where the paramedics had a chance once on scene....and apparently this is a benefit of the shock causing them to "pass out" (why they fell down when shot, many people don't, primarily when very high or determined), but it's theorized that unlike older bullets that icepick through, the newer ones cause a sudden rapid loss of blood pressure, but the body responds with a defensive shock response which consolidates blood in the core vitals meanwhile lowering BP in the head, leading to loss of consciousness. Even the core vitals lose pressure as well, and the vessels change from this defensive response to prevent rapid bleeding out due to heightened cardiovascular activity when frightened or angry. The shock shuts tgat down, and this seems to sometimes buy the victim time... not to do anything, but to simply not die yet. Obviously this is a problem if no one gets you help, but if they do, their chance of survival in a good ER goes up unless the shock is too deep and brain damage results. It kind of blew my mind because it revealed that a stop=/=a kill. In the 20s-50s some police departments actually called their 38s with lead round nosed bullets widowmakers, because it was all too often that while they were plenty deadly, the enemy didn't always stop fighting before bleeding out, and thus could shoot back resulting a kind of mutually assured homicide unless you have cover or overwhelming force (shotguns, surprise, etc). Hollow points reduced this trend until drugs seemed to somewhat reduce the effectiveness of almost any stop, at least some of the time. Obviously this mechanically relates to hunting as we all want an ethical kill, but that starts with a fast stop unless that stop comes at the cost of a recovery. But if you can get both, problem solved. Unfortunately, most hand held options can't just Avada Kadavra a tough animal. So it's hard to be as merciful as we might want to be.

⁠@@ravissary79the shock response makes sense with the animals I’ve shot in the chest cavity (heart/lung only) that drop instantly. They’re dead before they recover from shock with destroyed lungs and grazed or exploded heart muscle. I would only expect instant death from a brain shot. With a spine shot anywhere in the neck/back I would expect paralysis and possibly, but less likely, hemorrhaging. Of course a spine shot in the front half of an animal will eventually cause vital organ shutdown which would be instant but not immediately noticeable.

Can air not be displaced now?

@@hrdrockfarm8948 sure it can. But they haven’t done testing to see what that displacement is. Everything is based on fluid and gel. Which behaves entirely different.

Wont let me post the photo

If anyone’s wanting the photo lmk I can’t send

Love your videos by the way

I'll bet it was. Were you pushing 85-grain bullets about 3,300 fps?

Gods, I've made and seen plenty of spinal column hits and near hits and they've always paralyzed the animal's hind quarters if struck behind the withers/shoulders. Struck in front they either stun temporarily or killed outright if spinal cord is severed. I've had several neck-shot deer go down and out, but then jump up and run off from a near spine hit.

Billy, that is a classic use of the 220 RN .308 bullet. Typically gives deeper penetration. But I've found a good 180-gr. will do the job. Ditto 150-gr. Barnes X from a 280 AI and once even an all copper J-36 from a 6.5-06. Oh, a 130-gr. 270 WSM gave a one-shot kill on a bull moose for me. Yeah, all bullet designed to penetrate well and retain weight seem to do the job. Benefit of the high B.C. versions is extended range and more retained energy at all ranges. But 220 is certainly not overkill.

Good point!

Size and SPEED!

@firstchoicemechanical1403 Wouldn't expect you to understand .. go back to your Big Gulp refill.

I've been reloading for a Rem 700 ADL 270 for 45 years. The only change to the factory production was to free float the barrel. Tried many different factory 130 gr cartridges and only Hornady shoot moa. Tried 100gr, 130gr, and 140gr with different powders and couldn't get consistent moa. Was using for big game hunting so I tried Sierra 150gr bullets and soon found a consistent moa load. Have used only this load for the last 30 yrs. Your barrel will probably have an appetite for a different load.

It may not be called "hydrostatic shock" , but testing by the FBI has proven that when the velocity of a projectile is above 2100 fps when it contacts the body, the organs are stretched past the point of recovery. That shock is what causes death.

"hydrostatic shock", testing by the FBI concluded that when projectiles hit a body at speeds above 2200 fps stretch the organs past their point of elasticity which is what causes almost immediate death. kzfaq.info/get/bejne/ipybiNmanJjXYI0.htmlsi=jZ9eNKxBJnAj_xdC

If the valves in the heart are open upon this impact, then the blood vessels on the brain have a chance of rupturing, but much less likely if the valves are closed.

This is incorrect. Have you ever shot a deers in the lungs with a rifle? The lungs are basically turning to jell. They dont just have a 30 caliber hole in them or even the diameter of a bullet that has opened up. It's not a myth, just depends on what you are shooting on how effective the hydrostatic shock is.

Depends. It also works on animals. But there many variables. Bullet design being a big one. Velocity is another. I haven’t hunting that much, but I have taken a few whitetails with jellied heart/lungs. They usually drop straight down. But I’ve seen other people just have a wound channel and a tracking job. And the calibers varied.

Certainly worth considering. He's a veterinarian as well as PH, so has been around the block. But I'd sure like to see some evidence/proof. The difference in diameter between a spire point and flat nose is so tiny and they get so expanded/mangled so quickly...

@@RonSpomerOutdoors The podcast was on the Big Game Hunting Blog, from about 6 months ago. I’m not promoting it, I’m just passing along his information. My experiences with PH’s is they don’t care much about technical details as much as results. It’s worth listening to. Thank you for all the Great Videos. Stay Safe and Well.

In the same way as velocity impacts, yes but not a crazy amount
