group No.1 197grn sized .310
group No.2 first shots with 170grn. sized .308
group No.3 170s second shots to get closer to aim mark
group No.4 170s moved over to get on the vertical line
so i can see some promise here with the lighter bullets and thinking i should try the bullets closer to 150grns.
there were a couple of shots that made a bang instead of a wosh so speed is a bit quick, maybe drop the charge 0.5 grain of powder.
i will load 20 rounds next time and shoot a few 5 shot groups at 100 yards with the 170s and see how we go
