I've been told that swamped barrels are not used much at serious offhand matches because they are not as accurate.
Is there any truth to this one? MD

Roundball, I really don't think that is correct. I would like to see the data on that myself.roundball said:Rifleman1776 said:"...the swamped barrel absorbs harmonic vibrations which would otherwise affect accuracy. Swamping makes a barrel more accurate for this reason..."
I had no idea swamped barrels absorbed harmonics and are more accurate as a result.
Please post the link to the source data for this.
In fact, the link to the source data would be good for permanent inclusion in the 'Articles Section' of the MLF for the benefit of all members.
Claude, you'd agree to this, correct?
:thumbsup:

Centuries ago when swamped barrels were invented there was no established science or knowledge base about harmonics or any way to measure them.
Pretty sure most who buy swamped barrels do so for the lighter weight and better balance that their design provides.
:wink:
:haha: :haha: Maybe not exactly the way it happened, but here's a blurb from 1789 which amazed me, just by showing that they were investigating such stuff.Stumpkiller said:"Have decided I don't know a thing about barrel harmonics this day, it having been not yet discovered, and so beat the portion near the muzzle of my barrel more severely than the end nearest the breech meerely as I was angered with my apprentice and wanted his inletting task to be unpleasant."
Pieces intended for shooting with ball, whether they be plain or rifled, ought to be of much more equal thickness from the breech to the muzzle, than those that are intended for shot, only. In every barrel, there is an undulating vibration communicated to the metal by the explosion. This is most remarkable in a thin barrel, and when the charge is great; and may be rendered very evident by the following easy experiment. Take a piece of fine steel or iron wire, that is tempered so as not to stretch readily; pass it once around the thin part of a barrel, and twist it tight. The piece being then charged and fired, the wire will be found burst asunder, or considerably untwisted. It is evident, that such a degree of vibration in the barrel, must have an effect upon the ball in its passage through it; and that the only means of preventing it, is, by having an additional quantity of metal in the barrel. and especially in the fore part of it. The same circumstance certainly obtains, though in a much less degree, in fowling pieces; and on this account, as well as on that of the recoil, a barrel which is strong enough to withstand any charge that is required, may yet have too small a quantity of metal in it.

No jugs were injured in the making of this post. :rotf:
