I use nothing but Longshot and especially in heavy field loads.

GO to the powder manufacturer websites and look there thay have all the published recipees available.

No there are other option but you need to research it. Either get the loading data book form Alliant and Hogdon, I prefer Hogdon or just go to their websites. Punch in your requirements, components etc and they will tell you what different options there are.
