[QUOTE="J E Custom, post: 436893, member: 2736"] I not only understand how they work and also why. I think they should be avoided if possible. if you want to shoot factory ammo of any type in a light weight barrel then they can offer some advantages but will have to be tuned for each and may still not shoot some ammo well at all. And the reason a heaver contour works better is that they are not only stronger and resist any whipping/flexing better. Also the weight prevents more movement than a light contours during firing. A short barrel has the same effect compared to a long barrel of the same contour. You will never see a #1 or #2 barrel on a bench rifle but with some match weight restrictions a lighter barrel is a must, so weight is added to the muzzle end where it will have the most effect for the weight added. In other words you can take a light barrel and with weight added to the end it will act more like a heaver contour. Most bench rifles are very heavy strait barrels that are very short in order to take advantage of this weight and length. they also normally glue the action to the stock to add more of the total weight of the rifle and reducing the harmonics even more. Harmonics are the main cause of poor accuracy and any way that you can reduce or make them predictable and consistant shot to shot, the better and more consistant it will be. Light weight/contoured barrels can be made to shoot very accurately but they are also more sensitive to load differences, so they are harder to find an accurate load for and normally only like one load. Good Bedding and Gunsmithing are critical on all rifles but even more important on the light weight rifles and the tuning systems may improve those that are lacking in both, but you will never see a boss system on a heavy barrel because they are not nessary. A heavy barrel will be easier to find a accurate load for and they will normally shoot everything well, and will have many good load possibilities. I don't know if I can explain it any better than that. A light weight barrel has only one advantage "Light weight". A heavy barrel has only one dissadvantage "It is heavy" everything else is an advantage. If there is a reason to go with a light weight barrel you must except the consequences and deal with them. But like many things that only address the symptoms(Like tip pressure, tuners, excessive barrel floating and more) instead of the real issues Hanging something on the end of a barrel to make up for there deficiencies instead of building it right in the first place is the easy/cheep way out in my opinion.
