MLKEITH,I plan on making a trip up to Cabela's after my 777 is all used up.I plan on getting two pounds of Black Mag'3 to do my own testing with that stuff.I hope it shoots as clean as i've heard.what charge of powder would get me close to 100 gr. of777 to get me started?
If you are shooting 100gr. of ffg 777 you should be able to duplicate the velocity or exceed it with 100gr. of Black Mag'3. I find with 300gr. bullets the BM3 actually gives more velocity than equal volume of ffg 777 and felt recoil is less. Lighter bullets may not give the same results as the BM3 seems to prefer heavier bullets. In any case I would limit my max load in a magnum rated rifle to 120gr. of Black Mag'3.
