Sako M10

[baldie]

Quite a rare rifle here, probably due to the ridiculous price, but a nice rifle non the less.

The customer decided he wanted a .300 Norma Magnum barrel for it.

Sako don't do it, neither will they sell the barrel extension. Not helpful Sako.

A 338 bolt, barrel and magazine kit was purchased, and the barrel extension robbed to make this barrel up

The barrel extension is very simple, and I have no doubt someone will make some.

A 1-9" Sassen cut rifled blank was chosen, in a heavy varmint contour, I use a lot on AI rifles, modified to suit the Sako.

Finished at 30" long with an M18 x 1 muzzle thread and fitted with my new 4 port brake.

Painted in Cerakote graphite black, in house as usual.

If its run in, in time, hope to see this in action at Gardners this coming weekend.

Is there a particular reason why some rifles use a barrel extension ? I'm assuming that it could be for one of two reasons:

1. To have a larger diameter available to work with at the receiver end without needing the barrel to be of the same diameter
2. To use a different (tougher ?) grade of steel at the breech end whereas the barrel may be optimised for wear resistance

The extension contains the lugs, so yes, it has to be a harder, different steel.
