After over a year of reloading on my L-N-L i have only tried 2 different powders, H335 and W748. Since then i have learned alot from purchasing those powders and what seems like i will never know enough. In my search for 2-3 powders to experiment with over this summer looking for recomondations from those who have experience and will give pro's and con's which powder and why. I never really new when someone stated 'thats a dirty powder' what that meant until recently. Will be trying 40GR and 50GR balastic tips and possibly a heavier one,HOR 68GR). Powder does NOT have to be a ball powder but do not want to have the ' flow troubles' some have with using the powder drop on my press or similiar. Any comments as to what i should be looking for and what to avoid are welcome. Looking to get more accuracy than i have found with the H355 and be a little cleane
