On a progressive press, how much C.O.A.L. variation is normal? I have a Hornady press that has more than I like (I am picky). I sent the press in for repair (they replaced the ram) but the lengths after repair seem to vary more than I think is acceptable. If you load a box of ammo on your press, what variation do you get and what brand do you own? I am loading 380, 357, and 9MM. On the 9 and 380 I am using Lee 4 die sets.
