300 Yard group shooting with time limit

[Entry Level]

I don't have concerns safety wise. The mag cutoff works well, the finish of the receiver is ok. It isn't a custom rifle. the barrel is new so no worry about chamber. Usual caution reloading. Have shot LC Match . I don't use the brass that must be reamed to reload. I reload Remington brass, LC Match brass and just got order of PRVI new brass to try. My problem is older eyes and 2.5x mag on scope. The wood is clean, the inletting of action is in excess, could be bedded but then wouldn't conform to Vintage Rules. The scope dials back to 0 so no problem there. I will try and dial to 1000 next time at range. i will need probably 40 clicks, 20 moa from 600 to get there. I like the rifle fun to shoot. I chronied my 150 FMJ load with 55 gr. H-4350 at 2805 and it was comfortable to shoot. Will look for 2700 approx with 168 I plan to load next. From reading the earlier posts the gear has been improved from first issues. I have to remember to shoot the Gibbs first then switch to 12x42 NXS or Valdada or eyes rebel. A 7/8 inch tube is very different than 35mm.
