Alright, I've never found a good answer to this question...sorry this is out of topic line with the original post, but I must finally ask.
Why is it that a shotgun manufacturer can produce a fancy double barrel model in which the cost can be held around $1000, but when someone makes a double rifle, magically that number must be set to $20,000+?
I feel that essentially, double rifle manufacturers are ripping people off. Does anyone in their right mind really believe there is $40,000, or $80,000 worth of labor or parts on a fancy double rifle? I won't buy that belief, ever. I think it is downright absurd, actually.
When you examine the basics of a double rifle, or double shotgun, they seem to have all too much in common. One simply has a two rifled barrels which are thicker, and is regulated to fire at a certain range. There is no way those small differences can account for the price of another 20 firearms.
About the issue at hand, I say either use a pump or a bolt-action shotgun, my choice being the latter. Most importantly, use a gun which is very reliable, and a gun which you can accurately place 30 yard shots with while standing. You can have the largest gun in the world with you, but if you can't make a quick stopping shot to the grizzly, it ain't gonna matter.
