Hard Cast or FMJ vs. expanding bullets for wildlife defence

My understanding is that it all depends of what kind of wildlife you are likely to encounter and the cartridge you use.
It seems to be a trade off....if you have more than enough power to get to the vitals, then an expanding bullet will create a bigger wound channel increasing the damage otherwise you should try to penetrate as much as you can...am I right?

In my particular case, the 2 dedicated wildlife protection handguns of my collection are a 10mm semi auto (a S&W 1006) and a 44 Mag revolver (S&W 29 with a 8 3/8 barrel)

I use Double Tap full power ammo for them.

Assuming my above theory is correct, an expanding bullet may work in 10mm against a cougar (where you would probably use FMJ or hard cast with a 9mm or a .40) but you should use hardcast or FMJ against a black bear.

For the 44 Mag, a heavy soft point may work on a small-medium size blackie but you would want all the penetration you could get (hardcast) against the bigger bears.

Are my assumptions correct??

Yep.

And a flat point SWC hardcast will penetrate deeper and straighter then a RN-FMJ.

Yes, definitely flat nose....as far as hardcast or FMJ goes, I do not think there is anything other than FN available in 10mm, 357 Mag, 44 Mag and all the other big boys....no round nose that I know of.

I mght be wrong, never encountered one that wasn't in an enclosure myself, but I don't think kitties are that hard to kill, expanding for either of those calibers should be fine. If I were going to carry an expanding load for possible anti-wildlife use, it would probably be something loaded hot with Hornady XTP bullets, they expand some but they penetrate beautifully.

Lead Semi-Wadcutter or Lead Truncated Cone for maximum straight line penetration, whichever feeds best in your handgun. SWCs for the revolver, TCs for the auto.

Just my .02,

Saturno, your OP was pretty much right on target. Couldn't argue with anything you mentioned. I still like a substantial longgun (12ga up close, .300+ for medium range) for ANYTHING to do with Bears, but that's not always convenient. (ie: fishing pole in hands, backpacking, etc). I'm hearing good reports on Hardcasts though, as was mentioned.

What kind of wildlife? You would want a deeply penetrating bullet for a big bear, an expanding bullet for a muscular but not thick-skinned or heavy-boned mountain lion. (Or, for that matter, a two-legged varmint.)
