as in all hunting and defensive handgun use,
precise shot placement, and yes that requires practice,
and knowledge of the anatomy of the game is critical to success
and yes obviously your choice in weaponry and ammo selection ,

and developing your skill's in their rapid, and effective use matters
but it certainly helps to have good quality ammo, thats been designed for decent penetration,
to allow you too break bones and destroy the vital organs,
keep in mind that there's been a running debate over what caliber and pistol or revolver has been close to ideal.
and the fact that a bear is both difficult to kill quickly and that you'll have only seconds to defend against a charge.
which frequently is made from short-range cover.
having a large magazine capacity is far less of an advantage
if you only have seconds to react,
and quite possibly only time for one or two shots.
bears have been frequently killed with cartridges like a 357 mag or 45 acp,
but theres also been a few maulings after bears have been wounded.
read the link above,
having, a decent handgun and effective shot placement from that handgun,
is a well-proven defensive tool, if your alert, and skilled in its use.

having the best cartridge and handgun in your backpack is worthless

Id be fairly confident that a 500 mag using a hard cast 470 grain bullet ,
would significantly out penetrate the jacketed bullet used in the video test,
as they have far softer lead cores,
yeah, you would need to experiment with the powder and charge weight,

to maximize results
but the projectile is well known as a good penetration option,
as It seems to effortlessly exit large hogs that are hit

just a bit of info on these lee "440 grain" 500 S&W bullet molds ,
with the gas check and lube on these cast bullets,
at least using my 95% WW alloy and 5% tin, mix,
the projectiles actually weigh about 470 grains
they are quite accurate (WITH THE GAS CHECKS)
http://www.sagesoutdoors.com/500-s-w-caliber-gator-gas-checks
the best load for accuracy, after a great deal of testing.. 20 grains of blue dot
Its certainly not a max load
but its very accurate and it certainly hammers hogs,
you might find that a powder like H110 could add several hundred extra FPS,
but that may or may not enhance the depth of penetration.

keep in mind, that if you prefer a semi auto with a large capacity magazine,
the glock pistols in 10 mm have a 15 shot capacity and 30shot mags are available,

https://gunmagwarehouse.com/sgm-tactical-glock-20-10mm-30-round-extended-magazine.html

a hard cast gas check bullet weight near 200 grains will provide both deep penetration
(mandatory for good results)(as is decent shot placement)..
and if you want reasonable velocity in a 10mm hand gun like a glock model 20 or 40
youll need to hand load ammo in most cases, if you want to keep cost reasonable,
as commercial 10mm heavy bullet ammo can easily cost $1.00 a cartridge
obviously a 6" 10mm barrel designed to use cast bullets helps

if you graph out velocity vs bullet weight and test penetration, and calculate energy potentially delivered to the target,
you want something in the 180 grain-220 grain weight range

as always do the math and test your reloads,
for accuracy and flawless function,:rolleyes::rolleyes:

more than a few guys I hunt with vastly prefer a pistol caliber carbine over a handgun,
(most just find its a hell of a lot easier to hit well consistently with a carbine than a handgun,)
mostly because few handload and practice frequently

a decent 10 ga or 12 ga shotgun can be in practiced hands extremely effective defensively
the ithaca road blocker 10 ga is a very powerful weapon.

no handgun , comes close to the power level of a 10 or 12 ga slug or buckshot loaded shotgun at close range.

the marlin 45/70 or browning BLR in caliber 450 marlin loaded with a 405 grain bullet is what most pro hunting guides suggest and what they carry as its devastating at both close range and has the potential to reach out past 100 yards and still be 100% lethal with one well placed hit

the glock 10mm has gained a great reputation, and its very easy to handle and carry plus there are 15-30 shot magazines easily available

the old S&W 44 mag revolver in 4"-10 " barrel lengths is a well proven performer

the 500 mag might only get one shot off but if its well placed it should do the job!

if your life might depend on the results of the weapon you carry and how effective ,
you are with it, it makes sense to do your research
