I agree with the others on the TC clear measure. It seems to throw pretty consistent volumetric charges. I switched from the pellets to loose powder this past season and am pleased for having done so. Loose powders are much cheaper than their pellet counterparts and, once you measure and store an extra shot or two in tubes, they are just as quickly reloaded. The loose powder volumetric equiv., say 100 gr. loose compared to 100 gr. pelleted form, should provide more energy as well due to greater combustible surface area.
