Reloading Data Question

[Capt Roy]

I have a basic question about published reloading data..

On the Hodgdon website I looked up a load for .38 special it was Trail Boss and it listed 2.7 as the starting load with a velocity of 661. Max load was 4.2 with a velocity of 804.

What length barrel do they use to measure the velocity?

I would assume that a longer barrel, i.e., 4" vrs 6" would make a difference. I looked everywhere on their site but didn't find that information. Maybe I need to read their reloading manual better.

I guess this may not be necessary but I have always been the curious type..

Ahh... it's a secret!

Actually, if you go up toward the top of the page that shows you the load data, there is a button that says "Print". Click it. Even if you don't want to print, just click it. It will open up a new window that has more info, including the barrel length they fired it from.
