Factory ammo wont be cheap. I've found SBR 350 gr. FMJ's at ACME Sports in Seymore for $37 a box. He also had 300gr. JHP at $45 a box and Barnes 300 gr. TTSX for $60 a box. You can contact Andrew at Profire Arms (site supporter and licensed ammo manufacturer) and see if he will load some rounds for you... he's working on 100 for me. Your best bet is to reload. Brass is scarce right now so expect to pay a premium for it. Where are you located... might be able to point you where to look for supplies.
