My son just got a great find on a nice Arisaka which uses 7.7x58 ammo. Problem is we can't find anyone who sells this ammo. Does anyone know who might carry the ammo? We did find one box by Hornady locally at $42 a box of 20. But they are sold out and every site on the internet is sold out. Nice gun, but might not be such a good deal if we can't find ammo!
