After reading both Brozs comparison of the 210 VLD to the 215 Hybrid and 6.5 guys 10 rd load development I had to try. I loaded 12 rds in .02 GN increments starting at 72.2 and going to 74.4 of H-1000. 2 rounds being over book max. And just took it .040 off the lands. Working my way up here's what I got. 72.2= 2721 72.4= 2755 72.6= 2736 72.8 =2757 73.0 =2764 73.2=2766 73.4= 2787 73.6=2782 73.8= 2770 74.0= 2802 74.2=2794 74.4= 2816 Unless someone sees something I'm missing I'm gonna load a few @ 73.0 as between 72.8 and 73.2 has an ES of 9. The 2 over max never showed any sign of pressure. Not sure if I should continue up till I see those signs or not. I must say the Berger 215 hybrid show accuracy tendencies. 10 rds landed as you see in the picture. Between the a different bullet and the magneto speed my POI started 7 inches high and took 2 rounds to adjust the scope to put it were we see now. I was pretty impressed with thebullet seeing's this was just over a 2 GN difference. Close to home all I have available is 100yds.
