what does a Ruger #1 with a 26" barrel do to the velocity of a 7mm08? Does this length barrel increase velocity vs. 22" barrel as it would for a magnum cartridge?

Yes. How much you`ll have to crony to be sure.

Thmpr,

You will continue to gain velocity per inch of barrel even in the relatively small case of the 7mm-08.

In a standard length belted magnum case of .308" caliber and under, you will gain between 30-40 fps.

In one of the huge new cases, this gain can grow to between 35-45 fps. Especially from 26" out to around 32 inches.

The little 08 case will not get these increases simply because it used relatively quick burning powders and has a much higher expansion ratio then the big magnum cases.

That said, it will still gain velocity in a longer barrel.

Just guessing, from a 22 to 26 inch barrel I would expect 15-25 fps per inch. From 26 to +30 inches, I would expect to see an increas of 10-15 fps increase.

In my mind, the longer barrel would take away from the virtue of the little 7mm. In your Ruger #1 though, it is no longer then a 22" bolt gun with an increase of around 80 fps over a 22" pipe.

Good Shooting!!
