Barrel Band 2

Good Day.

Sometime ago I posted and asking for a lead to a two part barrel band for a Stromrider, I was not able to find the ad that talked about them. I was sure I had checked Ebay more than once but red faced me found one and ordered one. I came today. I installed it and the fit was good but it is a bit large. Pretty is what pretty does.

Shooting test revealed that it was shooting about six inches low at thirty yards. Shooting Hades I got groups of .41 inch twice. It would not shoot the AAs at all before but I tried just for something to compare to. One group was .39 inch and the next was .41inch. Crossmans still don't shoot. I don't think any barrel band can help them.

I am pleased that the band helped that much. Around ten dollars and the rifle shoots now.

I bought a 6MM REM once at a super deal. I soon found that it was not that good of a deal. In spite of all my efforts about 3 inches at a 100 yards was the best I could get. I was talking to gunsmith at a match and he said to install a pillow on the front of the stock. A little bedding and some magic I had a great rifle. After that dime size groups where the norm and with some loads even better. However I did not think of this in regard to being a pellet rifle.

Thank You and God Bless

Harmonic nodes..... Being that the stormrider is likely not regulated, your harmonics will not be uniform. Otherwise there would be an optimal harmonic tune for the barrel band specifically.

I always notice that on high end guns, if a band is used, it is mounted at the end of the air reservoir so that it is barely if affected by varying air pressures in the cylinder at all. Air vessels expand and contract, and that is not good when you want a solid, permanent anchor.

This is true to a point. Even a regulated Stormrider will have this problem however because the regulator sits in the bottom of the air tube. The pressure will be constantly changing on the high side. The SR has one barrel band near the action and a second can be added as in the thread I linked in the above post.

There is an optimal location for the second barrel band. Some have also suggested using an "O"-ring in the barrel band to minimize the problem you are describing. I don't know of anyone who actually did but a search might find someone.
 
Well, basically what I am envisioning is a tensioned barrel assembly that is already extremely rigid. Then a band that is fastened to the very end of the air tube. I do mean on the end, not any part that actually holds air. Stuck on the end of that. Pinned so it cannot rotate at all, ever. And it would slip over the barrel very tightly without actually holding the barrel in place per-se. More of a guide or retainer, not a clamp. Like this it would be free to expand forward or backward slightly, but should overall retain it's position linearly.
