I've known Dugaboy for a number of years and he and the group of thugs he runs with are about the last word in double rifles, They know their stuff! they shoot them better than well, they are hunters and a good bunch of outlaws in anybodys book.. I only use a double to hunt Buffalo, Hippo, elephant, and Lion as a back up..and I do love them. I know they can be very effective up to 200 or so yards..I have no doubt that I could put one in a buffalos shoulder at 200 yards or perhaps 275 or 300 with the given iron sights that are on my double as I have filed them in for 100, 200 and 300 yards and they will hit at that range and a buffalo is one big target. Have I done that? NO! but I have shot buffalo at 125 to 150 yards on several ocassions with my 450-400 and my 470..but even with a good scope sighted bolt action I seldom shoot beyond 100 yards on dangerous game, on one ocassion I shot a buff at 227 long steps with a 416 Rem and that was my only instant kill on a buffalo in about 150 kills. I don't think I would hunt our Mule Deer in Idaho with a double, but I know that Rusty and at least one of his cohorts would do so and my bet is they would both come home with a buck.. Personally, I see the double as compared to my 30-30 in range and ability to hit, except its more powerful. Don't be mislead here, I can flat out shoot that old 30-30 I was raised with it in my saddle scabbard and a buck at 200 yards is dead, standing, walking or in a dead out most of the time. I see the double as a wonderful rifle to have if you can afford one, but I would always want a couple of good bolt actions on hand. We each see rifles, cars, dogs, horses, and women in a different light and I wouldn't have it any other way.
