Got My Equiptment... Need Data!!!

[Tophernj]

I finally got all my equiptment together and am looking for data. I have the Lyman book, but it doesn't list a load for the components that I will be using. I am loading:

.357 Mag cases
Hornady 158gr. SWC/HP
CCI Small Pistol Magnum Primers
IMR Trail Boss Powder

I wound up with this combo because of what I have been reading combined with the fact that the only place with bullets in stock had these.

Any help would be appreciated and if you can provide a backup source of info, that would be great as welll.

Thanks in advance.

I'd suggest you foreget using the Hornady jacketed bullets with Trailboss.
Not a marrage made in heaven!

Find the data for the Hornady XTP in the Lyman book and pick a more suitable powder.

Or, if you have Hornady swaged lead SWC bullets?
Hodgdon powder website has Trailboss data for 158 grain lead bullets.

Bullets are lead SWC/HP. Not jacketed.

From Hodgdon website:

158 GR. CAST LSWC IMR Trail Boss
3.2 Start Load = 754 FPS - 16,500 CUP
4.2 MAX Load = 865 FPS - 20,400 CUP

I googled "Trail Boss Powder" and found a wealth of information. Well, at least a dribble.
