Multi barrell accuracy

Is a double barrell inherently more accurate than a single barrell? I was thinking about it and H&H has a enviable reputation among the "dangerous game" crowd. Harmonics are a big factor in accuracy, as I have proven to myself. Wouldn't two (or more) firmly joined barrells be more accurate? Vibrations from the bullet traveling down the rifling would be cut in 1/2 at least.
It seems to me that a 3 barrell gun would be the max before appreciable reduction in vibration could be measured. This does not include tubes supported intermittently down the length of the rifle (think Gattling). What do ya'll think?

I will say this, all the turkey shoots I was in all my younger years and then some where pellet counting was the winner. Barrell size and full choke or double barrell no holds barred just one rule, that was the shot sounded like one, if not disqualified. I went at least a hundred times and I only saw a double Barrel win twice out of those times, and a 36" goose gun win once out of those times. How and why, you got me. We all had same loads and pellets and powder just different guns. JLC

That's worth pondering. We all know that the shooter usually means more than the gun but I would have thought that the O/U or side by side would have had a better success rate.

nor do i have all the answers.having said that here is my hypothesis.yes i think the harmonics would be reduced by adding another barrel,but probably not to the point where you would notice the improvement.i think if anything a second barrel impedes accuracy because any sighting system would have to be mounted directly over the centerline of the bore on each barrel for real accuracy like on all standard single barrel guns.every double barrel ive ever seen has one comon sight system right in the center of the two barrels.it seems to me if your sights or scope start off off of center,it would only get worse at longer distances.i just keep thinking of my experiences with double 12ga.just my thoughts on the matter.you have me interested now though,hope lots of people coment with their experiences

Your hypothesis is correct, to a certain point. If the center of the chambers offset is the same distance as the center of the muzzles offset, then the poi would, in theory, be that same distance. This could be less than 1" in many current chamberings. That 1" should carry to extreme ranges if accuracy is improved by stabilization of said barrells. Again, this is only theory on my part.

doubles

The double's reputation for dangerous game doesn't have much if anything to do with accuracy....managing very high pressures, high recoil, and an immediate second shot compared to standard arms of the safari heyday (1860s-1940s) have a lot more to do with the double-as-standard for safari use.

'Regulating' a double-rifle (adjustments to get both barrels to shoot to same basic POA) can be a lengthy and expensive process, esp. with cartridges that are $20 each. So many reknowned big game hunters have taken so many game (even elephants) with military bolt action guns with relatively low-powered cartridges (8mm Mauser, etc.) that I think the double is more of a mystique or choice than a 'must'.

The double also costs a lot more, since you must have 2 excellent barrels, properly regulated, to get even practical levels of accuracy. Your 'best' barrel could be hampered by a 'not so great barrel' mated to it.

The 3-barreled German drillings (3 barrel) are also held in high esteem across the pond, but again compared to modern bolt-actions I can't see how a double or drilling can do any better, esp. without greatly increased cost. A rack grade .458 Win from Ruger or another affordable brand will do the dangerous game job with aplomb, since it's mostly close shots over open sights on angry critters. A Dakota or other high grade hunting bolt gun can get just as pretty without the hassles of the double.

Fox, H&H, Beretta and the other bespoke gunmakers are artisans...but their art isn't that much more accurate or functional than the 'ugly' guns at half the price.
