Welcome to the forum from Oklahoma.

 

Welcome to the Forum!

 

Welcome aboard from North Texas. I’m not sure that I’d trust my life to a .40 against a pissed odd lack bear. 10mm on the other hand…

 

I took his post as asking about a recommended load for a G 40 in 10mm although I could be wrong,I knew when Glock announced the model 40 in 10mm was going to result in this confusion.

 

I think it's a G40 (10mm). Anyways, I've been happy with Underwood's Xtreme Penetrator line in my .44 mag, not that I've killed bear with it. The bullets are copper, not lead.

 

Underwood 220gr hard cast. They have a coating on them that makes them okay to shoot through Glocks.

That would be my choice, hard cast lead, for myself coated or not as I'm one of those heathens that shoot bare lead in Gastons OEM rifling and has for over thirty years and gun and heathen remain.

 

Welcome to the Glock Forum

 

Buffalo Bore or Underwood is fine coated or uncoated. I've shot both and never had 1 issue in my glocks. I currently carry a 1911 10mm in the woods in N. Georgia and on my property for bear as we have a bunch that like to visit the lake in my backyard. I got some Hornaday hunting rounds loaded up just in case a bear decides to get to close (not my 1st choice) ,but I'm confident it will get the job done.I also got some rubber shotgun rounds to scare them off the property if they try and get over my fence. So far they've been good bears and stay to themselves.

 

The buffalo bore seems to have ammo in stock pretty consistently but I did read a lot of people saying they wouldn't use buffalo bores ammo in their glock g40 10mm from lead fouling but couldn't get enough information on it to make a proper decision. I've had a lot of run ins with black bears when I used to hunt near the coast of NC in hyde county and they always just went the other way. I was 16-18 years old at the time and really couldn't have cared less about bears, now I laugh at how stupid I was lol. I used to go out and hunt with 2 PB&J sandwiches in my pack and wondered why I had bears at the base of my stand or more encounters than anyone else. It wasn't until a couple years back when I was walking out of the woods with just a phone flash light and had a momma bear and 2 cubs walk out 5 yards in front of me on the trail out when I realized I should probably be more prepared hahaha

 

If you're just using the ammo for self defense then the lead won't build up. Years ago I had alot of Buffalo Bore hard cast 10mm rounds and decided they all needed to be shot at a tree. I shot atleast 200 rounds out of my glock 21 with 10mm upper and had 0 issues. You'll be fine with Buffalo Bore if that's what you choose.

 

Is this the buffalo bore ammo you were using out of your 10mm? HEAVY 10MM OUTDOORSMAN Pistol & Handgun Ammunition

 

I got 1 huge black bear that's always around and if I didn't like bears and ate bear I'd take him when the season opens up. I've seen alot of black bears and he is by far the biggest I've ever seen. The dogs also seem to keep the bears at a distance with their barking.

 

10mm should do it. But, you would still need to hit the bear coming at you.
I carry a gun and rifle while hunting for the same reasons, but I was told that the best bear defense is bear spray.

 

The whole no lead from a Glock is over blown to start with,98% of the ammunition shot out of my Glocks,9mm,40 S&W and 45 ACP are grease groove and more recently coated lead alloy bullets.I load 10 mm but all of the arms it is used in are revolvers

If one matches the lead alloy to the pressure of the round lead build up is nil to non existent and this is the key to not leading any bore,I have been using lead bullets from OEM barrels for over thirty years and not problem one with the barrel or arm.

I am a bandloader and caster, the only ammunition I don't load for is 22 rimfire and ammunition for self defense use everything else I produce for myself. A year back I stated polycoating or better yet HiTec coating, less time consuming and less messy than grease grove lubing.

Anything that Buffalo Bore or Underwood is loading is fine to shoot from your Glock 10 mm and would be my choice for your intended use.

 

Underwood is what I carry In the woods of NW Montana. I have shot both the Underwood and Buffalo Bore. No issue with either. Just stay on top of your cleaning. If you shoot it, clean it.

 

This is all ya need for bears....lol!

 

Why am I picturing the old indian in Legends of The Fall, when he says, "It was a good death."

 

I'm pretty sure that was it. I think it was called something else though and it looked a bit different. It's been some years since I had it so I'm sure they changed a bit. I also had the dangerous game ammo that they sell. Both worked fine....atleast on the deadly tree I eventually unloaded them into.

 

I had a g21 then built a 10mm upper for it and loved it. Then I decided to do a Rowland 460 conversion to it and use the 460 rounds for bear. I have never shot a bear so can't say much on actual real life stopping power. Now I've taken a few deer with a 10mm and it did the job very effectively.

 

I had to shoot an Elk with my G20. Double tapped & it was over. I had just hit it with my H2 going probably 35 mph…fwiw, lol!

 

If I was going to mix rounds for bear defense. I’d maybe consider the Underwood 220gr linked above, & maybe these.

I thought I saw mixed ammo in one magazine brought up a few posts ago.

 

Anyone? Lol. I have a few boxes for my ruger super redhawk alaskan

 

This is the post where 300+ grain bullets come up.

 

Appreciate all the info folks this was super helpful. I called Underwood today and their customer service was top notch. They also confirmed I’ll be good to go with the glock g40 10mm and their hard cast bullets. They also let me know their .45acp hard cast bullets would work great in my smith and Wesson shield so I’ll be ordering some for that gun as well for the time being

 

Underwood’s customer service is part of the reason I buy a lot of their ammo.

 

If you mean a G40 in 10 MM then hard cast Underwood. If you mean a Glock in 40 cal, then hard cast Underwood.
Lots of well intended advice here. The thing is can you handle and shoot 300+ grain ammo at 1400 fps velocity. That is a handful for anyone.
I've seen first hand what the .40 Underwood 200 grain hard cast does to a charging sow (pig) that weighed in a shade over 300 pounds. I'll also tell you it took near a full mag to put her down. Fotunately there was that sort of time, and the young uns she was so irritated about were plenty big enough to fend for themselves. BTW, every round entered and exited. the fourth to the brain pan finally shut her down. All were lethal hits, but adrenaline and pure rage is a hell of a drug.

 

Just like anything. A fatal shot can take a while to take effect. Any pistol should be a last ditch effort to save your life…maybe against a large charging animal. This thread is just about how to get the most out of that last ditch effort, imho!

 

These were taken by my neighbor in Montana. About 1.5 miles from my property. Yearling Griz with a deer kill.

 

Huh thats a different kind of bear "pissed odd lack bear. " 😁 but any bear pissed off I think I want a 10mm

 

Also the hardcast is perfectly fine in a glock stock barrel, it's mainly just cast lead bullets that you have to worry about. Of course I usually only run a box or two per range session and I always clean my guns later that day after the range, but any of the big main companies as long as it's hardcast, I've never had excessive leading or fouling. Just don't use anybody regular lead bullets. On the Buffalo bore website the owner even goes into the issue at length and stakes his personal and business reputation on it, and he wouldn't do that if he was putting his company at risk to say that hardcast is safe in a stock glock barrel!!! He has tested it extensively!!! I've used buffalo bore, underwood, double tap, and grizzly cartridge in hardcast personally with no ill effect whatsoever!!! I prefer the underwood 200gr hardcast, and underwood 200gr xtp for non bear work. They consistently get the posted speed if not a hair over for me.
