Thread: 1 shot groups (cold bore challenge)

We’ve got some interesting velocity data here.

This is a couple more pictures, not quite on the exact topic of cold bore vs subsequent groups but related:

First group after taking off stock and reassembling. Screws at 40 in.lb

The first shot was the one at 5 oclock.
This was prone with no rest at 100m.

A bit of light relief, some gun prn:



I came up 3 clicks and tightened them to 45 in.lb.
20 shots later (dont look at the kneeling and standing …) and here is the sitting , again no rest or sling:


Possibly not as scientific as Gimp’s Quality Assurance but supports previous experience that its OK to take the stock off and put back on for this sort of shooting.
