Back in godonlyknowswhen, Zastava started making Mausers. They made them for the military, but their commercial production was pretty good too. A powerful lot of these were sold by George Herter- he put barreled actions together and even sold whole guns, sold this rifle as a J9.
Somewhere in there even Brownells got into the action, selling receivers and whole guns, at a pretty good price.
Harry McGowen put his hands on some and barreled them in 30-06, and I have one of those. The stock was nasty but I fixed that, and the scope mounts were horrid but I got new ones from Talley (Best rings I ever bought or used) and the trigger was abominable so I got a Timney, and the scope I had was sort of awful so I bought a Nikon Monarch 3.
This is the completed rifle on firing day, awaiting only it’s Made in America Harris Bipod.

Anyway, I had gotten it close using a laser boresighter, and at the range I put a big shit-n-c target downrange, sighted the barrel on the huge dot provided by the target, and adjusted the scope to match it.
The first short was high and away. I held the rifle in position and moved the crosshairs to the hole, and took the second shot. it only took two clicks to get it in from there, and I filled the magazine and shot five times. Here’s the target.

This is at about a hundred yards with the scope set to 2.5 power. yes, there are five holes in that group, and you could pretty easily cover them with a silver dollar. I am most pleased.
Now I need to get trigger time, and that means a bunch of snap caps so I can teach myself never to flinch, and a lot of ammo so I can make sure it goes downrange. This is the first time all the pieces have come together for this rifle- trigger, scope, mounts, stock. I will have to get used to the nice as the suck I had before was so permeating. If this all goes well I will rebarrel this rifle, still in 30-06, but with a crowbar, a barrel heavy enough to impose it’s will on the round. And then I will start shooting at things which are far away.
