Can someone tell me the approximate velocity, energy, and/or pressure loss I'll see in a 4" ported barrel 44 mag vs. a 6" barrel? Most of the loads I've seen published (and I admit I haven't looked far at this point) use a 6" test gun, if not an 8". I'd really like to be able to calculate the numbers for my 4" using the supplied 6" or 8" data. Is there a formula that can be applied?
Thanks in advance,

P.S. I don't own a chrono.
