I'm looking for some proven loads to go to Africa when I get there. I have a cz 550 and am going to use 500 gn bullets. Probably hornadys but not sold on that yet. I'm looking to be in the 2250 fps range. I dont want to have any sticky bolts or anything when I get to the heat of Africa. Any loads out there or powders that seem to be well suited for what I'm trying to do? Thanks.
