Does anyone know how or why this OD became the standard for heavy .22lr bbls? It's kind of a funny dimension. |

Or have the barrel thinned then tensioned. That is machine the barrel down to roughly .30" and then install a tube over the barrel and tighten it down with a can on the threaded muzzle. When you tighten down the cap it slightly stretches the barrel. I have done this to several barrels and they help keep the weight down as well as seem to help make the barrel more consistent with a wider variety of ammo.
Here is a tensioning setup I did on a 7.62x25 chambered Savage. It was designed to shoot heavy bullets at subsonic velocities. It is a bit thicker than I would normally leave them be I wanted more metal in case I decided to go 7.62x51 later, but you get the idea.

It's the diameter of a ruger 10/22 barrel right in front of the receiver. Less machine time to leave it that diameter the whole way. I personally can't stand .920 steel barrels cause the weight. thats why you need a magnalite carbon fiber .920 barrel http://i805.photobucket.com/albums/yy336/dakotakid10/100_1026.jpg This I my MR rifle in 22 Mag came with one from the factory. I love the rifle and barrel. |

Ok, .920 it is; I ordered a tactical innovations 1:9, threaded, stainless heavy bbl. Now I need to find a way to mount something like tech sights to it and still be able to thread on my suppressor. Posted Via AR15.Com Mobile Nodak spud makes a slip on or clamp on .920 front sight set up but I think it is just meant for their 10/22 peep, but it might work. |

Posted Via AR15.Com Mobile I'm not sure how accurate those are with normal 40gr. ammo. I think those are special made for shooting the 60gr. SSS ammo. Normal .22LR is 1:16 |

The diameter of the barrel right in front of the receiver is critical to give proper support against the extension that the V-Block screws into.
When it is loose there you get barrel droop. After that, it can be any diameter. And, our NDS-23 front sight will work with a variety of rear sights

Normal .22LR is 1:16 I guess I'll have to see about this 40gr ammo in the 1:9. This carbine will be run with a suppressor 99% of the time, so the SSS cartridges will be used.

It's got a pretty fast powder to make up for the lost case volume with the longer projectile. Powder hasn't finished burning when the case gets extracted. |

Posted Via AR15.Com Mobile 38 & 40gr work just fine with the 1/9. I have a Volquartsen SS1/9 as a host for a STW integral for about three years now. Eats most anything. The SSS works well, but my sub-sonic of the month are CCI 40gr HP's, #0056. |
