8.5" 12ga vs bear

I don't feel like digging the pics up but here's the MVs of 3 slugs I chrono'd out of my 8.5" Grizzly.
Remington Managed Recoil 1 oz advertised 1200 fps, 8.5" hit 950 fps
Royal Brenneke 1 1/8 oz advertised 1410 fps, 8.5" hit 1080 fps
Federal 1 1/4 oz slug advertised 1560 fps, 8.5" hit over 1100 fps
I can't remember the exact numbers but there you have it. At 10 yds those slugs are moving just as fast as a longer barrel drives them out at 50-75 yds. Do your part and that's a dead bear. You don't need a longer barrel unless you want one. A short barrel works just as well and in some cases better (reduced chance of fragmentation) Carry an short shotgun in the bush when you're actually doing something and you'll have a whole new appreciation for them.

So basically you go down from a respectable 30-06 class energy (Federal 1 1/4 oz slug @1560 fps should be about 2955 ft lb) to 223 one with 8.5" (1 1/4 oz @1100 fps or 1469 ft lb)...I had not heard anyone recommending using a hot 223 for bears...

The "factory" figures are from a long barrel, which generate much higher velocities with slugs than even a typical 18-20" defensive gun barrel.

The lower velocity well be a good thing, at least at short ranges though, as "soft" slugs at least can fail rather dramatically if they impact faster than their limited structural integrity can handle.

I've seen them severely underpenetrate or even flatten out into a disk and "frisbee" out the side of the target.

Anyways, shotguns are effective moreso because of mass and momentum than energy, IMO.
 
I am curious how many people asking if a slug will kill a bear...even actually seen one in the wild? Or live or even frequent where bears are more then a weekend a year at a rented cottage surrounded by 100s of other cottages? LOL

or if anyone replying here has actually had to fire upon an advancing or charging bear before...
 
I hope you're not recommending a .223 for bears. That would be stupid. A 12 ga. slug with similar energy however performs very different with almost 500 grains more weight behind it. Velocity is not the only factor. If a cyclist hits the side of your house at 25 km/h he will hurt himself and maybe damage your siding. If a fully loaded logging truck hits the side of your house at 25 km/h you're homeless. Same velocity but the heavier one f**ked your life. Noteable difference. Check out Brobee's shotgun penetration tests on YouTube and shotgunworld. At full velocity the Federals stand a good chance of fragmentating and giving up penetration.

Nicely said. ;)
 
A stick is the best defense, a dull one is preferred.

why?

because you think only experienced bear encounterers should be asking about what to do in the event of a bear encounter?

that dont make NO sense. those who have encountered bears lots would already know what to do, and those who havent should be the ones asking.

he was talking energy, not velocity.

to equal the energy a truck at 25km/hr contains, a bicycle would have to be going so fast it could penetrate your brick wall and kill you, due to its DRASTICALLY reduced mass.
 
I've seen lots inside the city, let alone in the wild.

I've never experienced a charge or even a bluff charge but I've seen a lot of bold and stalking type behavior from bears that seemed to be accustomed to humans.
 
Wrong, the bicycle would fragmentate and blow an 18 ft wide, 2 ft deep hole in the side of your house. It would rattle some things off your coffee table. That's why they say you should wear a helmet. Neither energy nor velocity alone make an ideal or even useful number for a projectile. To compare numbers while ignoring very important details is not intelligent. .223 is not well suited to heavy bone. Soft 12 ga. rifled slugs are, especially at reduced velocity. At 1100 fps there is not much risk of fragmentation and 547 grains delivers very deep penetration through tough medium. Driving a 55 gr .223 bullet fast enough to match the energy of a 547 gr .730" slug does not make the two equal or the argument that one is basically the other. There is hoards of test data to back that up.

I am saying for the amount of threads on this subject one starts to wonder...

Slugs are commonly used for hunting bears IF a shotgun is what one is allowed or choosing to use...so why wouldn't it be okay for those RARE "what ifs"?

Use high end slugs, ones MADE for big game that penetrate well and not the $6/5 round box from Canadian Tire. Use them both in a gun that you are comfortable using and familiar with...something that holds more then 2-4 rounds like SxS or O/U or a super shorty does is ideal...may be longer and heavier YES but you have more rounds and the recoil is less making for faster follow up shots and the swing IS better on them. Be smart and aware and carry bells on your pack on you if your not hunting and you should be okay. If you see a bear at a distance you can always keep eyes on it, and make ready with your gun all well going out of you way to AVOID it!!! Again...how many bear attacks happen a year? (and remember you gotta BE in bear country for a BEAR attack to have a chance of happening!!!)

Lastly...a longer and heavier gun gives you a better club!!! :p

Just out of curiosity what type of slug would you reccomend? I have been told that brenneke KO slugs are the bomb but I have never even seen them in person.
 
Brenneke's are cast of a harder alloy and feature a raised nose rather than hollow point to minimize expansion and reduce (but pretty much eliminate) fragmentation at higher impact velocities. The end result is a slug that can handle hitting soft targets at magnum velocities and hold together for very deep penetration and some serious wounds in really big animals. Rifled slugs are for deer, Brenneke's are for everything including but not limited to: deer, moose, bear, trucks, airplanes, giant squid, kittens etc.

Brenneke makes great slugs...hare to find tho. Rottweil makes some great slugs...easier to find and same "style" as Brenneke I believe (made in the same place as the Brenneke brand slugs I THINK). The whole thing is a tad confusing but my point is both make good slugs, just buy them from the right line as they make many different types of slugs for different uses.

Federal has some nice stuff, their "TruBall Rifled Slug" I have READ good things about, never personally used tho but my father and uncle both use and love their "Trophy Copper Slug".

I am sure Hornady makes some nice ones too.

You are wanting a slug that can PENETRATE as well as expand (some)...most slugs out there are soft lead...take one a part a hit it slightly with a hammer and see...and will not hold together and go as deep as a nice Brenneke or copper slug will. These slugs do cost more but they perform much better on big/dangerous game!!! Most have a bit more bang to them as well :p
 
Amazing how the best posts in the thread were ignored.

Read these if you're actually serious about it.

I see a few problems, although I doubt that terminal performance will be one of them. The first is how well are you going to be able to shoot the gun? Even if we ignore the short sight radius for the moment, a barrel as short as 8.5" is too short to balance the gun, so it will be butt heavy, it will feel clubby, and it will be slow to get on target, compared to a similar gun with say a 14" barrel. There isn't much magazine capacity, maybe 2 rounds. But the the show stopper for me is the possibility of my hand inadvertently slipping off the slide and moving in front of the muzzle just as I fired. No thanks. I don't want the barrel of a pump action shotgun or rifle to be so short that I can extend my support hand past the muzzle when the gun is shouldered.

Well you're right about the necessity of hitting the brain or spine, but you're wrong about pretty much everything else. No animal commits himself to a charge from 100 yards out, at 100 yards he's just moving towards you. In a defensive, rather than a hunting scenario, shooting early is wrong. The closer the bear is to the muzzle, the less chance there is of missing that relatively small target, and a brain shot will rug him right now . . . provided you destroy the brain; simply shooting him in the head might not be enough. Of course one needs the correct mindset and a knowledge of bear behavior so that the potential danger can anticipated, and we must practice before we're faced with the real deal, but it doesn't take superman to survive a dangerous bear encounter, just competence and a cool hand.
 
Sold mine and never looked back mine wasn't SUB-BARN in 20 yards I originally bought mine for bear defence but seeing the accuracy I went a different route
