I was bored and had a reamer from years ago so I built one this weekend. I barely got to shoot it before dark last night to get it on paper at 25yds. I loaded 60 to 64grs of H5010 in 1 grain increments and then loaded 5 at 65 and 5 at 66grs. The first shot was 60grs and it was pretty mild so I jumped right to 65grs. Then I shot a 3 shot group at 25yds with 65grs just because I could barely see the target at 25yds and I knew it would be pointless to try 100yds. It shot in the .1's which was no small feat since I could barely tell where the crosshairs were. It was too dark to get a reading from the chronograph also. Hopefully I'll get another chance tomorrow to see what this load is doing. Any help on loading data would be helpful.
