In the first place, nobody makes "CHROME" cases, or chrome plated. What you probably have is NICKEL plated brass.

Second, unless you have trimmed all the cases to the exact same length, AND they are all from the same manufacturer, you cannot expect velocity consistency.

Start over. Sort your cases, then measure them until you get enough the same length, or trim them all to the same length. Then when you crimp, you'll get the same crimp each time.

Third, crimp does not equal velocity increase. Crimp is simply to keep the bullet from moving under recoil from the round that's being fired. If this is 38 special, then recoil isn't much of a factor, IN OTHER WORDS, a light crimp is all that's needed.
