Well , picked a few loads to try some 3 shot groups(100 yards) and see if anything would be of promise, either I really suck or or I gotta change something.
Yes , I am pushing limits here and not doing things the optimum way but something should click somewhere.
I have my COAL at 3.500" so that I can fit into the magazine but I will lose my capacity as a repeater if I go much longer.
I could go to 2.525 ish and still have 25 though clearance but it's getting tight.
There were two other groups of Retumbo of 80.5 and 81.0 which echoed the group size here.
The first 4 groups are IMR7828.Adjusted the scope after the first load of 71.8 to stay in the center of the paper, so there is no confusion as to where the big movement came from.
The Retumbo IMO is slightly tighter and more consistent over all but hardly worthy of settling on at this point.
The RT loads start to be compressed around 78.5-79.The 7828 Is almost there at 72-73.
Should I play with seating depth a bit ?
Say F it and treat as a single shot?
Start with from zero with different components?
I have not yet determined COAL in relation to the lands yet as I was going to initially try stay within the capacities of the box magazine.
Velocities were where I expected.
The last two Retumbo loads.
