Vall,
My situation is the opposite of yours, I form 8x57R/360, 8x58R S&S, and 6.5x58R S&S from original length (2.125-2.130") 38-55 cases (a little short but work if I seat the bullets "out") and I'm down to about 20 of them. Current 38-55 cases are the same length as 30-30 and I count them by the gallon instead of "each" and I don't own a 30-30 rifle.
Mike
