Is 10mm Underappreciated?

Fire 15 rounds at a running bear. That's some theory.

The theory I read is - fifteen 10's (with certain ammo) MAY be better than six .44's under certain conditions. You may be running around a tree, picnic table or have a little distance, have a natural barrier that may slow it down, etc. Shooting a short-barreled 44 mag quickly, under intense stress, while you and the target are moving will probably produce numerous (if not all) misses.

Thats exactly why I carry a .22 in bear country. Just to shoot a colleague in the knee or ankle.

You don't have to outrun the bear just your hiking partners.

I've hiked Brown Bear country numerous times and I've taken my .44 mag wheelgun with me. I'm not a huge ballistics guy, but I've done some (internet) research and have found that the .44 mag is much better for stopping a bear, but you only get 6 rounds. Fifteen rounds of 10mm, although not as powerful of a round, gives you more of an opportunity to hit an attacking bear while running, screaming, wetting your pants, etc.
(never run, 'food runs')

This theory can work on two-legged animals also.

Now thats just funny, just make sure you have peanut butter all over your face.

Dude, you seem like a good guy. As someone who builds guns, understands how they work, and talks to reamer and ammunition makers with some frequency, be careful.

ok I do not build guns ,but have read about the Glock 20 in this case shooting .40. I am open to listen and learn. I need to understand why in simple terms it is not wise to do so? We are talking just the Glock 20 in this conversation.

Be lucky to get one or two shots off on an attacking bear. lol

Not to be to argumentative, but comparing a real 10mm to 40sw is like comparing 38+p to 357 mag. Buffalo bore 180gr are going something like 1350fps. If you compare that to American eagle 10mm that is going 1050fps,then yeah, it's not much different than 40.
A far as setting a glock 21 up for 45 super, why not just get a 460 rowland barrel. My friend has one on a g21. 230gr at 1300fps. 44 mag performance in a semi auto. It's crazy.

I like the 10 mm as a side arm when hunting with a rifle. But this year I'm using a sw500 . No second gun needed

The research will show it's a VERY bad idea.

[Hannco]

Because 10mm is hotter than .45.

Then step up the spring of a Glock 21 and try .45Supers...

I think most of the commercially available 10mm are watered down version and not the load as it was intended.

[GunsNGolf]

.40 and 10mm have very similar balistics. Not sure I see the benefit of the added cost.

[Dan 0351]

I would think that 15 rds of 10mm would be preferable to 5/6 rounds of 44mag or even 454
