Interarms mark X

[Ggmac]

168 grain. Have a few others to try. This was the load that was pretty consistently under an inch for him before.

168 for hunting? Try the 180 semi round nose or semi spitzer . I have one of these in 30-06 and the 180 is the one it likes . It does kick harder but these have a long throat and the 180 fits it . The 220 works also but is too much thump

Now run jb or Iosso abrasive bore paste through it. Without a bore scope it looks shiny to the eye when it's still full of carbon. Chemicals alone don't touch hard carbon.

Those Zastava Mauser actions are very nice! I would send it off to Douglas for a rebarrel. It is definitely worth it. Go to a 7-08 while you are at it. Take care of it and it will be an heirloom rifle to hand down to your kids.

Before you rebarrel…….


My Father’s Interarms mark X in 7mag never shot worth a darn until I free-floated the barrel and added pillars and just devcon bedded it. It was bought used way back in the 90’s for $200(probably because it wouldn’t shoot well) and I finally put a decent adjustable trigger on it and did this other work. It used to “pattern”, not group, kind of like the rifle you are working on.

Many of these older guns have been tightened and soaked with oils, and repeated, and have sunk the actions and barrels into the stock. My $.02….

Have the barrel scoped, check the crown and rifling carefully, bed it, and try heavier Ammo. I started reloading for this one and am running some 180Gr Berger hunting VLD’s and it is now a 1/2moa or better rifle.

Yep, was gonna say that old Mausers fail this way. The action wood crushes over time and the "pillar" on the front of the floorplate where the front action screw goes touches the bottom of the receiver and you have a loose action in the stock. Quick way to tell is put some shims or washers under the floorplate to give it more draw and go test fire. If it helps a quick fix is to simply file .010-.015 off the top of the front pillar but a good bed job would be best.
Not that the barrel is not at fault either. I just replaced one on a Sako that had never been cleaned by my uncle and fired very little. The bore from the muzzle to about halfway in was a gravel road, worse that ww2 mausers Ive fired. The result of hunting in the rain and riding in back of a pickup for years.
