hello everyone I have been mia the last year and a half from here burnt up most of my ammo horde and getting ready to start pulling the handle again but I built a new toy over the weekend 300 bo 16" 1/8 twist I think. pistol lenth gas system got dies. jig. flare die. and a lee c312-155-2r 6 cav mold on its way. now to my problem out of the stackes of reloading manuals I own the hornady 9th is the only one that has 300 blackout data and no lead data in it I have always used lyman manuals as a guide for all my cast reloads so where is the best place to get published cast bullet load data at? and any input on the lee 155gr bullet ill be loading this is my first attempt at casting for rifles and with a good poly coat is the gas check a must for that bullet I don't know how may post and forums I have checked any I see peoples pet loads but haven't see any published data thanks for taking the time to read my post
