I have a .338 RUM (same one I posted the range report for yesterday). I have spent lots of time, tears and more $$$ than I care to admit trying to get the darn think to shoot better than 4-6 moa. The list of things I did that added very little accuracy below.
1st- Added a muzzle brake. The thing was so painfull to shoot out of the box that I can't even call the results a "group", more like a casual gathering of holes on the same large piece of paper. Also checked stock to action screw tension etc. The brake got me down to maybe 8" groups.
2nd- Floated the bbl, glass bedded the action, cleaned up and lightened the trigger, also had scope mounting taps enlarged for bigger screws.. All at once. Now I started printing the 4-6" groups, still not what I'd call good for long range work.
3rd- bought a higher magnification scope (went from 3-9 to 4-12). Groups were now a little more consistantly 4".
Finally-Started fire forming/neck sizing only, reaming flash holes, turning necks, weight sorting cases, and fire lapped the bbl. 1.5" groups on first range outing.
As you can see I didn't follow the scientific method of changing one thing at a time. In your opinion what is the most likely thing that improved my accuracy from 4" to 1.5"? Or do you think it was a cumulative thing?
