Typically I reload everything I shoot, but at the price we can get Wolf ammunition, it's just as cheap to buy the stuff.
To date, shot over 3000 rounds (2500 Wolf and 500 S&B) through my 2 Bushmasters - never had a problem of any type.
By the way, Cabela is selling 1000 rounds for about $95 (with 4 ammo cans - the used military .50 cal boxes). Go to their "Bargin Cave" portion of the site. They are currently selling FMJ and HP in 55 and 65 gr.
