Finally got the scope installed and locked down, but only had time to do the 50 yard thing before packing for a cowboy action match at the end of last month.  Guessed at my sight setting and with 10 shots divided up between 100 & 300 yards, won the long range optical category side match with this rifle & scope.  Came home and finally got around to getting everything put away and cleaned up.  Decided on Monday to go to the range and do some more fine tuning with this rifle.  Found two screws loose on the rear mount after having my "zero" at 100 yards jumping around on me.  Totally frustrating day!  Came home tightened up those two screws and made plans to go back today.  Locked the rear sight in place with the back pf the scope misadjusted.  Shot about 7" left!  And obviously, I had to have forgotten to take the screwdriver set!  Time to reload some more ammo.  I'm tempted to take this scope off, re-install the modern scope and do a bit more ammo testing with something I have more confidence in holding a "zero".  The front of the scope is mounted in the front dovetail, almost to the point that right side of the mount is even with the right edge of the top flat.  Seems quite a bit "off"... Currently the rear mount is pretty well centered over the top flat and mounted in the holes provided for a front scope ring.  (Behind the rear dovetail).  When shooting @ 50 yards the scope is bottomed out in the mount.  !00 yards is one mark up.   

On another note, I also purchased a Longshot "Marksman" target camera.  What a pleasure to be able to "mark" each shot on my tablet and take a snapshot.  Shots 1 - 13 were from Monday, then #'s 31 - 67 were holes off the target that were preexisting from both days.  Today's shots were #'2 68 - 80, with 81 being unmarked when I saved this screenshot.  Every shot was using an aimpoint on the right edge of the target with the horizontal axis centered in the bull.

I'm quite discouraged, and now question whether any of my scope adjustments are valid, or even in the right direction.  Today I didn't have my padded front support, so some might be due to bouncing and the difficulty I had holding my eye centered the scope, somedays maybe one shouldn't shoot!   

Put blue Loctite on any screws that hold the mounts, and don't need adjusting. It will help hold everything in place, and maybe allow the mounts to not need replacement yet.

Got back to the range & shot for a 5 & a 10 shot group with the new load of 14 grains of 5744.  This yielded a 1469.1 fps ave with an ES of 34, SD of 11.5 and AD of 9.9.
