Here is my latest load development with the 230gr HV GS Custom bullet.
The two barrels are slowly coming together, this is the closest I have gotten them so far.
The purple load is now both barrels, two shots each, all in 2 inches at 30m. (extreme spread centre to centre is 39mm)
With an increase in velocity the top barrel has been moving left, closer to the bottom barrel. What is slightly concerning is that the bottom barrels group seems to be opening up slightly, or maybe I just had one bad shot...?
If I can improve on this slightly I might get my desired 4 shots in 2 inches at 50 or 60m
The work continues.
Slowly slowly catch a monkey...
HB.
