Glock 10mm bear loads

I carry a G20SF with a Lone Wolf 5.5" fluted, threaded barrel. It is cut for a razor red Dot and I can get 4" groups at 100 yards supported, and 9-10" groups standing. 200gr hard cast at 1275. The other great thing about the Glock us you can practice with cheaper 40 s&w ammo. I shoot steel challenge with mine and post pretty good times. I have a holster on my pack belt and a clip on the slide so when I drop my pack I can put it in my waistband the same way I carry a pistol every day. Whatever you choose, I suggest you practice with it a lot. Find a club and shoot some comps with it. You'll get better practice drawing and firing than any other way. And it's a lot of fun.
 
Glock M40 10mm is what I carried to Alaska with Underwood hard cast loads (in a very comfortable Kenai chest holster). I was surprised when I stopped in a gun shop in Kenai they had a large selection of 10mm in stock. Including Buffalo Bore and Underwood.
You won't want to shoot cast bullets in the polygon barrel unless the bear is chewing on you. Accuracy is just not there! Go to you tube look up Hickok 45 testing accuracy of Glock 20 and cast bullets. You might be surprised! Those that are saying you'll be fine probably don't own one, I do. Of course they also aren't the one whose butt might depend on it. JMO. Luck
 
Personally, I was in the camp that 10 mm was not sufficiently powerful enough to rely upon to stop a grizzly charge. A recent trip to Alaska into bear country caused me to re-examine this issue. I can shoot my Glock well and fast but what bullet? My research led me to the G9 factory load for the 10mm. It is a factory solid copper designed specifically for deep penetration through resistant material (Body armor) . It will penetrate ballistic gell 36" before stoping, cutting a wicked wound channel. Penetration into vitals is the key to disrupting the nervous system and or circulatory system of a apex predator. The G9 was also designed not to deflect. I trusted it.
 
Still...
Two basic issues..
#1 platform (weapon type). Revolver or Auto to be used.
#2 load, bullet, weight, material..lead... .hardcast...jacketed....soft point

As to #2, African hunters have proven the value of solids. They penetrate straight, break bones and reach vitals. I would contend griz are more like African buff than lions or leopards and in most cases we are better off with hardcast solids for large bears. Why is this so difficult to grasp or understand? A bullet, shoft lead, pure copper, lead and copper poor even soft points driven at pistol velocities don't penetrate as reliably as hardcast lead.

Point#1. Auto pistols provide increased rates of fire, we have all seen the armchair comando rip a full mag in a second or two....so what! How accurate can one be? Apologies to trained operators reading this but we mortals will not get the performance differentiators trained pros get from autos. We will be lucky to get one round off when needed in an attack. Look at the bear incident reports from the last few years...most identify that shooters have already been in physical contact while trying to present a pistol and fire effectively. Cocking a S/A revolver is a step most would be challenged with? Racking a round into the chamber of an auto while being chewed on is darn near impossible.
This post keeps going back to bullet weight, design and powder charge? Would it not be more wise to think about the delivery platform first and then think about what we know to work? Thinking about how to enhance the 10mm it's fun but it's not going to pay off no matter what after market barrel is used.

Why would you have to rack the 10mm? Wouldn't you be starting with one up the pipe? Test after test has shown 10mm hard cast to penetrate 36-48" of gel, and consistently provide exit wounds on elk sized animals. I've shot revolvers quite a bit. Hunted with one successfully as well. But when it comes to getting a round on target quickly, nothing compares to an auto. It still takes practice, but how many practice with their revolvers vs autos? I'd bet 95% of the guys here shoot an auto better than a large frame revolver. Either way, shoot what you're best with and practice with it if you're going to rely on it. And any way that you can induce any kind of stress, that's better too. I shoot 1000+ rounds of center-fire pistol every year and a good portion of that is 40s though my 10mm woods gun.

Do you think being able to shoot more than once is a bad thing? You're right, most shots under this type of pressure will be misses. Me, personally, I'd be really glad to have a lot more chances for follow up shots to hopefully connect.

So keep one in the pipe. If the platform is reliable, which the Glock 20 (which most have referred and recommended) has been proven to be, time and time again, and a 200gr hard cast bullet, or 140gr extreme penetrator, will shoot from stem to stern on an interior grizzly found in the lower 48, then it seems as though it would be an appropriate combination for the scenario presented by the OP.
 
Going to try the Buffalo Bore 220 gr in my Glock. next yr going to Wyoming and will be packing it. Looking for a respectable handload since I have not reloaded in awhile. Do the 10mm Glock prefer any brass brand over another ? Thank you. Ed
Love all the great recommendations. My best recommendation is for ANY type of self defense use ONLY factory

Great recommendations everyone. My best recommendation is to ONLY use good quality factory ammo for ANY self defense. Practice and play with your reloads but quality control and reliability for ones life is trusted better with factory! Safe hunting!
 
Bear spray is fake news pushed by PETA and other tree huggers. Have a read:

your goal in one of these situations is to live, whether that means killing it or deterring it. Handguns work. Period. I have done a ton of research on this since I spend a lot of time hunting in grizzly country and decided on a glock 29.

What's the recoil like with the g29? I would like a 10mm and want one that's small enough I will carry it consistently and it seems the g29 is about the only compact 10. I really like the XDs' but they don't make the compact model in a 10mm.
 
Put a Storm Lake barrel in and load thàt puppy with Double Tap 230 gn hard cast pills, worked for me. One shot drop on a 400 lb Black .nuff said. Square in the chest.

That is exactly why I went with the 29 over the 20, it is small enough and light enough that I don't even notice it is there. Also, there are several comparisons and reviews that show you really don't give up much velocity by going with the 29 over the 20.

I don't think the recoil is bad at all. I actually shoot the Glock 29 better than the Glock 20...I know hickok45 said the same thing on his youtube channel, so maybe there is something to it.
 
Federal introduced a new bear protection load at Shot Show - looks like they will have it in 10mm. Its called Solid Core. Per their website:

Solid Core
Take down anything from hogs to bears with Federal Premium® Solid Core. The all-new line of handgun loads hits game harder with a tough, flat-nose lead bullet that holds together while blowing through bone, providing high weight retention and deep penetration. Syntech® polymer jacket technology reduces the friction and leading that plague hard cast bullets. Available in cartridges suited for both hunting and dangerous animal defense.
 
I didn't read every post, but has anyone done testing with Cutting Edge bullets in 10mm. They have some copper heavy weights if yer a reloader.
