9x19 is fine for black bear and under, there's videos of people dropping whitetail with compact 9mm guns from a stone's throw away no problem. But whenever you get into the caliber war it turns into a massive shitshow of what the minimum should be and why your favorite calibers are anemic, let alone handguns and the "puts holes in people" argument.
1) Nuh uh!, 2) all semiauto pistols are anemic compared to what is best to lug around for bear yeeting, 3) if you can do your part, a 10mm might not kill the bear before it gets you but they'll find its body not far from yours. Also 10mm is very cool and all the guys with big titty goth girlfriends shoot it. Just sayin'
Agreed. If using 10mm for backcountry defense you want 190+gr going 1200+ fps. Also avoid HP as they will open up too quickly to hit vitals.
200gr at 1200 is the magic number. Most of the commercial ammo marketed for backcountry defense is around that mark. Getting 180gr up to 1300 is tough without playing fast and loose with SAAMI MAP.
Most common round involved in bear defense shootings by virtue of being common in general and being better than carrying nothing at all.
Most people carrying 10mm for backcountry defense are out west. It seems to be following the trend that trades some performance for a lot of magazine depth.
I mean when it comes to registration, the ATF honestly treats it as tracking the tax stamp, as legally speaking, the ATF only has authority to inspect your tax stamps not the firearms associated with them since the Tax stamp is a permit for you to possess the specific firearm it's assigned to with a short barrel attached.
Picked one of them up that had been sitting on a shelf earlier this year, holy hell does it live up to the price tag. Hands down the best out of the box gun on the market, the end all be all of .45 design. Now all I need is to get the B&T suppressor and I'll be able to die happy if I never bought another pistol again.
Just remember, back country defense in bear countries isn't just bears, it includes humans too. That Montana camper that got murdered because some jackass got upset he took his favorite spot is a great example.
Just remember you'll need to mill out optics on the 75s. The SP/P 01 has a rail for a light, you should probably have a light for home defense. Just don't treat your gun as a flashlight unless you plan on putting holes through the object it shines on. Maybe also a suppressor...
The military EPVAT and SAAMI both use conformal pressure transducers to measure pressure however the placement of those transducers is different. SAAMI has it read through the case wall which protects the expensive transducer but requires a unique offset to account for the case wall. The military EPVAT standard reads at the case mouth and exposes the transducer to the hot gases causing excessive wear. Because of the location difference the pressure readings for the same load will be different and are not interchangeable. Also the distance for velocity is different. SAAMI measures velocity at 10’ while NATO specifies 58.5’. Most of these differences are due to the NATO testing procedure being developed first in the late 1960s with SAAMI refining it for use in commercial ammunition testing in the early 1970s.
Hmmmm looks a bit unsubstantiated....
What a total piece of utter shit Mark Milley saddled the US Army with
Lol the muzzle flash and report on these will be hilarious unsuppressed
and they are all still worse than .44 mag or .45 Colt. .357 Mag is marginal for large animals. penetration starts to be a problem.
Hardcast SWC will poke deep enough with .357 and even 10mm, the actual problem is shot placement under the duress of a huge fuckoff bear running at you.
Weight is the thing. with velocities such as they are in pistols you want weight so the bullet carries on through the animal. A 300gr .44 or .45 hard cast or bonded projectile will penetrate a bear/elk or cow lengthwise easily. especially long nose projectiles with the balance of the weight towards the meplat.
Just to confuse things more, the US military uses a testing procedure more in line with SAAMI so Technical Manuals end up listing the same ~55,000psi rating for "NATO" m855 as you get on retail .223 Rem, and then there's the euro C.I.P. which tests midcase like SAAMI but with an exposed transducer like EPVAT...
