So,....having experimented with a number of magnum and albeit slow burn powders many foul significantly. This is not to say they produce poor results but something is missing? Looking at QL and comparing load density faster powders can provide 80-90% fills and at least on paper far greater efficiency. To start: has anyone tried RL17 in the 300wm loading heavy i.e 208 AMAX and heavier??
Real world experience rather than guess work please.
