There are some "rules" for using certain powders in certain roles. Just trying to keep track in one location... Remember, you and you alone are responsible for your reloading and the results therefrom. I can't be there to do it for you and won't be responsible for your mistakes.
For Trail Boss: take a case, measure where the bullet base would be in the case, fill to that point, dump and weigh, and use 75% of the weight of Trail Boss powder. A good crimp and good neck tension is a must.
For Blue Dot: take a case, measure where the bullet base would be in the case, fill to that point, dump and weigh, and use 30-40% of the weight of powder.
For IMR 4918 use in Black Powder rifle rounds take 40% of the BP charge by weight.
For Hodgdon 4895, take the max charge listed, use 60% for cast bullets. This will give you 1200-1500 fps and you can adjust your charge from there.
ReplyDeleteThis 60% rule only works for 4895 powder.
