500S&W ammo?

[Axle2010]

Hey guys i just ordered my first 500 in a 7.5" performance center and looking for ammo suggestions. I know I'll need to reload to shoot very much to favorite recipes for that would be great but until then what's your experience saying is the best/ most accurate bang for the buck? I have some Underwood 325 jhp on order and of course I'll have to try the 700 gr hard cast but I don't plan on paying $100+ for Hornady or high end hunting loads just yet. I'll be shooting at home and hopefully turning a few pigs inside out to start with. Federal Fusion looks decent at a fair price, any experience with those? Thanks guys
