    I would like something handy for a multi-day dirt bike ride through the Rockies in Idaho and Montana.

    It would be nice to backup the bear spray with something around 4,000 # of energy, and I am trying to avoid spending money.

    I have an sps I would like to cut to 16 inches. What would this do to something like a 245 grained bullet that would normally go 2,875 fps at the muzzle? Would the recoil increase due to less length, or would it increase?

    And yes, I have read a million bear threads.

    less weight = more recoil. And you could loose 50fps per inch of barrel cut if I remember correctly. I think you may want to consider hacking down somthing cheaper, 12ga? Mosin Nagant? Cutting down the remington will likely result in a rifle that is inacurate and difficult to use. I would want open sights for bears anyway.

    16" 300 Ultra Mag!! Forget hitting the bear the muzzle blast alone will scare off anything in the tri-state area LOL. A sawed off 300 magnum would make it pointless, try tradeing for a 44 mag or something. 4,000 lbs of energy is not needed even for the largest bear, just use a high powerd handgun and get some deep penatrating heavy hardcast bullets, the world record polor bear was taken with a 44 mag.

    And you won't even be able to use it in dry/windy conditions.
    Starting Forest Fires is a no-no you know!

    In all?
    That has got to be the worst idea I have seen on THR recently.

    If you want a short light bear stomper, get a Marlin 45-70 Guide-Gun, or a 12 ga pump shotgun with slugs.

    Unlike a 16" 300 RUM?
    You might still be able to hear, and still see in dim light after touching off one round.

    300 Ultra????? What the? Just get a 12ga with an 18" or 20" smooth bore, open cylinder choke and load some KO slugs.

    Im with the NO!!! crowd. As they say, stumpy pump gun with slugs, short 45-70 carbine....or .338, or .35 bolt gun would be my choices. Hell a stumped nagant or other .30 cal carbine loaded with hot 180-200s would be a better choice then the RUM IMO LOL.

    The RUM is WAY too overbore for a 16" tube, heck a 308 is too hot for a 16" IMHO I like a 18" min for them. Ultra mag speeds are simply not needed for close range bear encounters. I agree that a large cal lever gun or 12ga slug will have every bit as much stopping power if not more, and they won't leave you flash blind and deff after the first shot LOL. Just remember you want penatration though the vitals not energy dump, so think controled expansion/hardcast not hollow point/ballistic tip

    Remington 870 or Mossberg 500 loaded with Brennekes. Lighter, more frontal area on the slugs.

    Cutting 10 inches off a .300 Ultra gives about the same performance as a standard barrel .30-06.

    Just my .02,

    I often advise that if you have to shoot a bear in self defense without tags / out of season, he'd better have powder burns on his fur.

    That won't be a problem with a 16" barreled 300 RUM. He'll be dead, skinned and cooked anywhere within 25 yards.

    Seriously it's a really bad idea. A cartridge like that needs a much longer barrel.

    Second that.

    When I'm in bear country, I usually carry my Mossberg 500 with Brenneke Black Magic. http://www.brennekeusa.com/cms/blackmagic.html

    I have a 300 Wby and a 30/06 carbine. I would pick the 30/06 carbine before the other. Cuttin down the barrel of a magnum eliminates the benefit of the extra powder. All you get is a lot more noise.

    Pawn it and instead of taking all money, horsetrade for a cheap slug gun and some cash. When you're done with your three day ride, you should be able to get your rifle back with no money really leaving your pocket. Just a thought.

    What's wrong with a good old .30-06? Or maybe an Ackley Improved version that'll also shoot standard '06 ammo? Find an '06 AI with 1:9 or faster twist and you can shoot anything from 110gr BT varmint rounds to 250gr big brown bear killers.

    He might not have one of those in his closet. See above. It seems he has a hacksaw though.. not that there's anything wrong with that.

    I hoping for something handy as in:

    very light and small. As I mentioned all the above suggestions have crossed my mind except I tend to think something weighing 5 lbs. max would be nice, not to mention that very short is nice too.

    I bet a .22 has taken a Polar bear before. Would you volunteer to sleep with just that next to you in grizzly country?

    I own some of the suggested weapons all ready, and was planning to take a
    454 Casull raging bull revolver and a Puma 16 inch in the same caliber. It would be nice to have more power and less weight than the carbine since I would likely only get off one shot. Just thinking the flash could help deter these guys that do not need vitals because they do hibernate.

    Thanks for the suggestions, and keep them coming!

    I really loved the video! What a nice chuckle!

    Why take a fine big game rifle and turn it into a worthless piece of junk? If you have that .454 Casull, you will be better armed than most people in bear country. If you really want something else, sell the rifle and buy a pump shotgun or whatever else tickles your fancy. By the way, that .300 RUM (in its unaltered state) would be great for bear HUNTING sted of bear defense.

    You may not want to spend any more money. But if you cut down the 300RUM it will be ruined. Just take the amount of cash you payed for it and flush it down the toilet, or buy a used Rem 870 12 ga. shorty for 200.00. That way you will have TWO good firearms.

    Just thinking SMALL AND LIGHT

    I have a pump 12 ga, but it is NOT small and light. I am considering the Serbu Shorty. Or a 10 gauge single shot, bobbed. Shorter and lighter than the carbine because the dirt bike has little carrying capacity beyond food, fuel, water, etc.

    My collection has much that would hunt Yogi the bear.
    These hunts would be at a distance, no doubt. I would rather eat popcorn than smoke ol' Smokey.

    It's just that I hate tents, and Smokey might be hungry in the late Summer. I believe
    in self-care. Think only defense please.

    Thanks, everyone.

    Bring along somebody you don't like and dip him in rancid kitchen grease. While the bear is eating him, you can hop on the bike and beat it. Just kidding of course.

    You do not have agood selection of slugs for a 10 ga and most 12ga can produce more energy with a heavy 12ga slug any how plus recoil is harsh enough with a 10ga it hurts follow up shots. The little serbu shorty as way better with buck shot as it need to be aimed and that is not its thang. Take the 454.

    Thanks for nixing the 10 gauge idea, hardluk1.

    There is not enough time in life to learn all about firearms.
    It's down to the 454's unless I get a 500 S&W revolver for a very good price.
    Anyone want to trade for a 300 Ultra Mag?

    Forgive me if I misunderstood but what does barrel length have to do with a cartridge being overbore?

    I'm with the 12 gauge shotgun crowd on this one....but hopefully you'll never need it.

    In an overbore cartridge like the 300 RUM there is a lot of gunpowder being burned compared to the bore area it has to expand into. Because of this the pressure in the barrel stays high and has a greater effect on the bullet velocity per inch of barrel. Some overbore cartridges like the 22-250 can lose up to 40 FPS per inch of barrel while straight wall cartridges like the 45-70 will lose less than 10 FPS per inch of barrel. On the extreme end pistol cartridges fired in rifle length barrels will sometimes have lower velocity than when fired in pistol length barrels because the barrel friction becomes greater than the pressure of the expanding gas.
