Just got back from the range after shooting some of my 1st reloads! I had a great feeling of satisfaction that is hard to beat! I am shooting a 7mm rem mag and loaded up 160 grn Sierra Game King over 58,59,60,61,62,and 63 grns of IMR 7828. The 61 grn load shows a good potential with a grouping of around an inch at 100 yds. The rest were 2-3 inches. My question is this; do I now work by increments of 2 tenths or so on either side of the 61 mark? And if i can't get any better than that should I start messing with seating closer/farther from the lands? Or just try another powder?
