A couple months ago, with the help of a buddy of mine, we completely reworked my 7mm.
Went from this:
To this:
Changed just about everything...trigger, stock, bedding, mounts, and installed turrets on a 3x9 leupold scope I've been using for a long time.
I've spent the last month trying a bunch of different loads (around 25), all with IMR4831 and with both accu-bonds and partitions but changing charge weights and OAL.
Went out yesterday and shot this group at 100 yards with the 160 accu-bonds, the last of the 4 test loads I tried yesterday...sighted 2.5 inches high at 100.
Last night I ran a ballistic table for a 250 yard zero, which I was sighted in for being 2.5 inches high at 100.
I also loaded up some more accubonds with that load and headed to the range this morning to see how close the ballistic chart was. At 300 yards, the chart said a 1 MOA adjustment was needed. I made the turret adjustment and shot 3 shots at 300 yards.
Next I tried the 400 meter chicken silhouette...spun up the adjustment and center punched it. Since that worked so well, decided to try the ram silhouette at 500 meters. Spun up the adjustment and drilled it dead center behind the shoulder. The last thing I did was spin everything to zero and took one last shot at 100 yards...right back to exactly 2.5 inches high.
The scope is tracking perfectly and load development is done...now its just down to the fun of shooting it and gaining confidence.
