I always find threads like this with a lot of WHAT IF's
if we can be honest, about any caliber can kill a bear , and yes even big brown bears and grizzlies and??
the thing that kills is shot placement
a little old .22 has been know to kill about every critter om the planet!
NOT the ideal tool or caliber of choose I am sure for most of us when dealing with dangerous game! and I fully agree
but the CALIBER has done it!
a .45 I am sure has killed bears
just like some folks win the lottery, it happens, like it or not, some times luck out win skill and caliber!
BUT if one was actually going to carry a .45 for bears
I think the bigger debate should be on what bullet load to use, and not just say, will a .45 work
as there is a huge difference in bullets and how they preform on impact
just as there is a big difference IMO< in what bullet one would want for self defense against a 2 legged predator, and a say a 4 legged extra large bear!
so, before saying "X" caliber is the better medicine, maybe one should really consider the bullet in "X caliber just as much.
if you get into so called EXPERTS(and I ain;t claiming to be one)
when you get into specialty ammo designed for dangerous game in HANDGUNS
, quite honestly most hand guns are not made to handle the added stress
if you follow hand guns, over the decades you will find dozens that had weak links, when shooting heavy loads
, due to they were designed around shooters shooting more mild loads!
you get into say 10 mm hand guns, and FACTORY ammo, you find very very little FULLY loaded factory ammo, minus the more custom ended stuff
due to most 10 mm handguns won;'t hold up to repeated shooting of it, not a bash on the 10 mm, I own several and even carried one in AK many many times for BEARS or ???
but the truth is, many folks don;t know as much about handgun ammo and bullets and what works best on "X"
they read a lot of internet blabber(and some might call this some too, its ok if you do)
with just a lot saying, you need "X" caliber,
but never get into what actual ammo to use in it
which can be very misleading IMO
lots of experts on rifles and reloading
but handgun info seem to be missing from a lot, and NO bash meant!
