Thxs rm, I suspect my scale is acting up so I ordered a new one which arrives tomorrow. If nothing else at least I'll have two to compare weights. FWIW my Speer manual shows 124gr JHP max standard load (35K psi) with Blue Dot to be 7.9 grns and resulting in 1238 fps. Appreciate the feedback with Blue Dot and case fills, it reinforced my thought that my scale is not reading correctly.My EDC load is the 124 grain V-Crown HP over 7.5 grains of Blue Dot.
Not quite +P at ~1180 fps but absolutely no case fill issues.
