[QUOTE="Lefty7mmstw, post: 991949, member: 48043"] I'll usually shoot a given bullet with both a single base and a double base powder and play with seating depth a bit to see whether it likes a jump or jamb. If I can't find sub moa grouping after two powders and load run ups with a jump and a jamb, I'll move on to another bullet. Another thing I do before I decide a load is good is to shoot it in multiple temperatures to make sure something isn't funky. This is more important with powders with more temp. variability, but even with the more temp. uniform powders things can change with other variables such as barrel stiffness. An example is my 7rum with 171 barnes and retumbo. In freezing temps it is a 1/2 moa load, but at 70 degrees it barely holds moa. [/QUOTE]
