Ammo , ammo , ammo. Buy as much as you can that will take you to the grave and leave 1 box left for the guy you sale it too ! I Am 60 years old and wish I had fewer guns that I shot / shoot well with ( 1 moa or less ) then a have a bunch of guns that shoot 1 1/2 to 2 inch moa.
**** TIP of the day ..... Keep in mind when you get older you might sale out the house and back 40 acres and live in a apartment. Not the best place to be reloading in. Nice to have 20, 000 rounds loaded and ready to go in your little 1 car garage. Don't ask me how I know. Ha ha ha. Marty
