Dusted off the old Mauser this afternoon, 1908 Brazillian, .280 Rem, 150 grain Remington CL PSP ammo...
First 4 shots went into a nice, remarkably straight line about 30 degrees from vertical and 12 inches long (100 yards). I quit wasting ammo after 4 shots!
Previous experiences with this ammo have been less than stellar, but 2" groups, evenly distributed, are the norm.
Scope problems? I've seen scopes die with vertical only and horizontal only stringing, but never diagonal!?!? It is a cheap scope, and I have a replacement at the house, but wanted to see if you guys had any other thoughts on a possible culprit. Leupold 1 piece base, dovetail/windage rings, well used Simmons scope...

You DID mention Simmons, didn't you? My first, last, and only Simmons would move POI 1" at 100yds in a NE direction for every power change on a 3x-9x variable. Simmons...never again!

Double screws...i.e. one big one for the action and a little one into a notch on the side of the big one. Guarantees (as much as anything can) that the screws are always in the same place when you remove and replace the action. I can try removing the set screws and tightening more...it is glass bedded and floated into the original (shortened) military stock.

...you probably have already thought of this, but if your crosshairs are not exactly perpendicular, you can shoot diagonally, especially if you are getting inconsistent ignition... instead of vertical stringing, you will get diagonal stringing....
[quoteI suppose correcting that requires either substituting a differently "timed" screw or shimming the action so the screw tightens up just as the locking notch aligns with the lock screw.
I was wondering about how one went about bedding an action with these lockscrews...and wondering if the bedding might be working loose. It has been out of the action for cleaning/rust prevention 10-12 times since I came into possesion of it, and the bedding well predates that. Anyway, seems like one would want to leave the screws a quarter turn or so loose while the bedding sets, so they can torque it down solid once the bedding sets. Maybe it is time to skim bed it...
I took a ruler to it once I got home tonight. Top to bottom hole, straight line is 10", or imagining a right triangle one goes about 4.75" right and 9" up. Draw a straight line between the 2 holes, and the other 2 holes are touching the line, and pretty evenly spaced too. Damn wierd...

Oh, yeah. That's a pretty secure setup, all right.
I've noticed that on some of the old milsurp Mausers, that setup won't allow the action screws to be properly tightened, as when it's run down to the proper torque it won't line up with a slot for the locking screw. I suppose correcting that requires either substituting a differently "timed" screw or shimming the action so the screw tightens up just as the locking notch aligns with the lock screw.
