If 10mm is ok for bears, why not 357 mag?

I think whichever one you could shoot more accurately would be the best. Relatively minor power differences probably don't matter much in the grand scheme of things. I would imagine that most bear encounters are pretty swift so I don't know how important capacity really is either.
 
also 40 sucks
Interesting how the public opinion on that has shifted. It was the darling cartridge about 30 years ago.

The hot ticket. A must-have. Everybody was making one and everyone wanted one.

More power and effectiveness than a 9mm more magazine capacity than a .45. It was all over magazine covers.

Then, a funny thing happened - 9mm rounds got far more effective. Speer Gold Dot, for example. Analysis of actual police encounters, and round effectiveness showed that the 9 mm was equally effective as the .40.

So, lower recoil, higher round capacity, cheaper ammo. 9mm became hot again.

I have witnessed a "full circle" in calibers. It is interesting as you put it. I agree. One example of this is the new 277 Fury, recently accepted and being phased in into infantry and special operation forces. 30-06 then 308 shortly, then 556, then back to a powerful medium\high power caliber.

We prepare for the war we just fought, you understand this.

The new m1152 9mm Nato round has more power than typical 40sw due to being a hot loading. Typical 45acp today has the same juice, around 440lbs. Seems like thats the number. 45 having an accuracy advantage over both 9 and 40. I would not be surprised if 45 came back as the "new" pistol round

I have never liked the 40 never owned a gun in 40.

To be honest, a bit of topic, I am surprised that 6.5 cm has stuck, time will tell. I dont own one of those either.
 
It's OK. Not great. Not terrible.

Ammo manufacturers did themselves a poor favor by downloading 10mm to equal 40SW. I think 40SW is fine as I stated, but would be more favorable to some if 10mm was 10mm, ie healthily hotter than 40SW.

Anyway I do have a 40SW Carbine. It's a fun gun to plink with.
Yeah, maybe saying it sucks is a bit strong and without filter. It will do the job, and do it well, i just dont like it.

I agree with the 10mm ''downloading''. 10mm is probably the best overall in power and mag capacity, until they dumbed it down to 9 40 and 45 power, then who cares what caliber.........

They will all kill a bear. some faster than others.

I have a 6.5CM barrel and upper that I have not quite finished building. That ammo is expensive - but I have a nice piece of glass for the rifle, so, I look forward to trying it out
 
I build a 6.8SPC AR around 8 years ago. It really is a sweet gun, no more recoil felt than a 5.56, but easy deer knock down. I know it's just me, but is more accurate than any of my 5.56 ARs.

Turned into a bastid caliber, but I have ammo and dies and bullets and brass.
 
I ordered 2,000 coated cast bullets and when speaking on the phone the owner said yes we have them onmthe shelf, I had to ask, are you selling much 40 any more. He said no. I find more 10mm brass at the range that 40 S&W and 38 special is rarer that hens teeth. I still am trying to wear our my XD Tacticle in 40 S&W , still it works great until it gets so dirty the cartridges fail to chamber.
 
He doesn't have a 40 barrel, he runs them through the 10mm. I'm surprised he doesn't have feeding problems due to OAL in a 1911 but he doesn't.
I’m surprised as well - I would think that 0.25” or so reduction in length would cause feeding issues and I’m surprised that there isn’t a bunch of issues caused by that same 0.25” set back from bullet to throat.

Look, I’m a 10mm fan, and own several guns in 10mm. Just bought a SA Ronin in 10mm this week, along with a case of American Eagle ammo.

But I save the .40 for my .40s. I don’t shoot .40 in the 10s.

I'm surprised it's reliable, the issue isn't really OAL but headspace.

Must have a pretty good hook on the extractor because that's all that's holding the primer against the breach face. Not sure I'd trust Kimber MIM to do that indefinitely, but that's another subject.

I have no doubt you will be satisfied with its accuracy

It is unlikely that you will ever wear out that gun, ever
 
My Glock 20 has been utterly reliable with 10mm ammo.

Are you saying that your Glock didn’t perform reliably with 10mm?

Or, as I read your post, that it was unreliable with .40 ammo?

Because if it is the latter, that is clearly on you. No firearm manufacturer condones firing .40 in a 10mm gun, despite what internet blowhards post about doing so.
Both... I am not blaming it for not feeding/ejecting .40 reliably.
 
Never had a Glock with a Glock barrel misfeed or otherwise FTF.

I have used .40SW Barrels (and 9x25 and 357Sig) in my Glock 20, which is the right way to do it. And some of those aftermarket barrels are a bit tight (LW) and need clean up, not a huge issue.
What do you mean by clean up? Reaming?

The only trend I have seen with Glocks was the gen 2-3 ejector not flinging cases out far enough, sometimes the case would fly straight up, and back into the chamber. Gen4 ejector solved that. I recommend the installing the gen 4 in a gen 3.

Interesting. My Gen 4 will intermittently malfunction if fired without a magazine inserted, my Gen 3 has never done that, ever.
