I've a Sako that has been rebarreled and restocked. The barrel has the markings of what I believe to be "H&Z". I'm at a loss on who this might be. Any help would be appreciated.

BTW, this gun came out of the middle of Montana, but I've no idea if this is where the work was done.

Are you sure the Z isnt really an S?

As in H & S Precision or www.hsprecision.com

It is not H and S precision. It is simply HS Precision. Doubt if that is who marked your rifle.

I'm sure it's not HS Precision, especially since the stock is wood. Also, there is no ampersand in their name.

I have seen Sako rifles that were sold by H&H in London.

These had the barrels marked "shot and regulated by Holland and Holland".
