Any luck finding Ammo?

Been thinking about getting an M1 Garand though.
Last I looked the Garand was no longer on the SA website, they still available new?? I have 50+ weapons stuffed into my safe. I think there is one in the garage. Have a 22lr revolver up to a S&W 500 Magnum, A couple of 22lr longs guns on up to a 50bmg rifle, all just because I can.....Hope I never need them for anything but shooting produce.....
