barrel 1to9 twist rate. Bullet was ABLR 129GR col was3.300 could cover the three shots with a quarter at 100 yds.
69.6grs Avg Fps 3151 es 45 sd22
Next up was IMR 7828sc
62.8grs avg fps 3110 es 7 sd 4
group size 1 1/2"square @100yds
Next up was Vihtavuori N570
70.7grs avg fps 3281 es 8 sd 4
group size was 1" square
The brass I am using max h2o level is 85.6grs no pressure signs on any of these loads.Got all load numbers from quick load best $150 dollars I spent. My question is where do I go from here do I play with seating depth or move out to three hundred yard to see how things go. Max range with this gun will be used is six hundred yards.
