Yep, I pulled out my reloading manuals and discovered that there is some snappy data that shows some awesome speeds for the 38-40, it isn't .357 fast but it is in excess of 1200fps in some cases. Of course I'll never push this old Colt to that level of performance and risk blown up parts in my face. I intend to just stick with HSM Cowboy Action loads at 930fps and enjoy this SAA often. I shoot this most days now so I can get the hang of the sight picture and ring those little 3 1/2" metal spinners at 25 yds. The trigger pull is a might stronger than I like, but I'm not ready to monkey with that yet. That reminds me I need to stock up on this ammo in the next week, must order a large quantity. I typically keep thousands of rounds for each caliber on hand, so it looks like this new caliber will be a keeper.
