cvarcher the only problem I have heard of with barrel bands is when they are too tight they can affect/effect the harmonics of the barrel. Every barrel has some form of harmonics as the bullet goes down the barrel, anything that restricts it from too tight of band to being snug against the mag tube can cause stringing or large group sizes depending on the particular rifle. I know one gentleman that reduced his group size significantly by placing a nylon washer over the mag tube post to reduce the contact between the mag tube and the barrel. Some rifles seem to be a lot more picky about things like this than others.

In general, anything that contacts the barrel is a potential variable...how much variation depends on how evenly it contacts, how hard it contacts, and how much the various parts vibrate and expand from heating.

Think there is a reason benchresters don't use barrel bands..or much of anything else that contacts the barrel in any way....but that's a whole didffernt world than hunting rifles.

Barrel bands seem to give their trouble was the barrel heats up...barrel metal will expand, and the fit of the barrel band becomes tighter...so the barrel tends to walk the shot a bit away from the cold barrel group center.

That's more of a range problem than anything else...not going to fire taht many rounds in a short time frame in a hunt (well..are some people that blaze away as if they are in a fire fight...but let's not encourage that kind of stupidity).

Hello,
I know that the barrell band on my Winchester '94 caused me a great deal f grief.The screw that holds it in place was bearing onto the barrell,andhad to be relieved.

Older Savage 340 bolt guns and Winchester 52's used a barrel band...can usually get them sorted out, but you just can't ecpect a wooden stock to stay stable under all conditons.

HAd a Ruger 10/22T that they had built with the front slight swivel stud too long...the barrel was balanced on the tip of that metal screw...would shoot two gropps, depending on what side of that point the barrel vibrated to bewteen shots.

Win 94 rifle..no barrel band, but the cross screw for the fore end tip was bearing unevenly AND was jamming the wooden stock into the barrel with considerable force.....got that one straightened out.

In general, would prefer not barrel bands at all....but sometimes you just ahve to elarn to deal with them when problems arise. NOt always a problem...can be fittted so that they effect is minimal, but from bot eperinece and looking at a lot of older guns, wood just won't stay where you pout it.
