Here are the loads you asked for. Cast bullet load Brass is Hornady. Primers SB. Bullet is 350gr cast from a Rcbs mold sized and lubed and (Daryl will like this) 44gr 5744 powder with 1gr Kpoc on top. The trick is getting good cast bullets. this is a mild load (especially for a CZ 550 safari) and is tons of fun to plink with. For a jacket load (and I beleave this one came straight out of the manual) Federal brass Federal large rifle primer IMR 4350 powder 93grs topped off with a 350gr Speer Hot Point. These are not hunting loads for large game just fun loads for shooting (or possibly deer hunting).
