ok
so your saying that right now until I fire them a few times, I will only need

(1) the dies
(2) powder, what kind? Hodgdon H4350 Smokeless Powder ?
(3) the shells them selves, I like the Sierra GameKing Bullets 243 Caliber and 6mm (243 Diameter) 85 Grain Hollow Point Boat Tail Box of 100


Then after I shoot a few times I should get a case length gauge and shell holder??
