DUCT-SEAL

[lone ringer]

Hello everyone, first let me tell you that I have experimented with a whole bunch of different products by placing them between the barrel and the stock of mainly .22 rifles to try to eliminate barrel vibration or at least affect barrel harmonics in a positive way. Anything that has a bounce to it does not work, cardboard placed at the end sometimes works on rifles whose barrels like to have some upward pressure placed on them.

The best product that I have found is called DUCT-SEAL and you can buy it at some hardware or electrical supply stores, if given the choice pick the one that shows the greatest range of temperature usage and the one that is hardest to the touch, stay away from the soft ones that would get even softer in very hot weather.

This product is known by the people familiar with it as monkey or elephant sh.. because of its appearance. I place a little (one ounce or less depending on space between stock and barrel) at the end of the barrel channel (last two inches) and then put the barreled action back on the stock and carefully tighten the guard screws, trim excess and take rifle to the range to see if it helped.

This is something that can be tried on those rifles whose barrels need to have some support and do not work well by being free floating. The stuff is cheap if you buy it at a local hardware store and do not have to pay shipping for it, less than $5.00 for one pound. I have been using the stuff for years and works for me. If you decide to try it please let me know if it works for you as well. I have used it in HP rifles as well and it does not melt.

I use it as the fill for my silent airgun trap. A 1 lb block is about $3.00 at Home Depot. Look in the electrical parts dept

Now this is the kind of gun smithing I admire. the person who came upon this idea is a true genius!

Do you think this might eliminate the first shot syndrome of the 547-T's etc?

I had trouble finding this stuff but now I have more than I need. Anybody who wants an ounce or so, PM me with a snail mail address.

Hmmm... This may be just the thing for a 504 I'm quarreling with! It has exactly the problem you describe - the barrel needs a little support...

On a different topic, where do you find shoe sole crepe suitable for butt pads?

Gator, I have not been able to eliminate the first shot syndrome that some of the rifles have but I believe that is due to the bullet's lubricant getting hard inside the barrel between relays or after as little as five or ten minutes have passed between firing the rifle.

I have five Anschutz rifles with factory barrels and will be experimenting with them to see if there is something we can add to the lubricant to prevent or eliminate the first shot going out of the group. In the mean time after shooting your relay put the rifle in a soft or hard case and try to keep the barrel from getting cold, that usually helps. Another thing you can do is try a different brand of ammo to see if it does the same thing with it.

For some reason most SS barrels don't do that so changing to a SS barrel is an option although an expensive one in most cases.

BlauBear, the tread about your 504 is what led me to share my experimenting with the Duct Seal material, thinking that it may help you guys. Fill the space between the stock and the barrel with Duct Seal if you have weight to spare and see what happens.
