I load 38 Special with Triple Seven for my cowboy action shooting. A friend gave me some 357 brass. I can not seem to find the same tables for load data that I used when I started reloading the 38 special. Hodgdon must have changed their website- or perhaps I am not looking in the right place. Does anyone know where I can find load data for Triple Seven cartridges?

Grayrock,

I found this on the Hodgdon site under muzzleloading. Page 2 of 3 you will find load data for 38 and 357 using Triple 7 powder.

Just curious, but have you tried using IMR Trail Boss powder instead of Triple 7? Trail Boss was specifically made for cowboy action shooters at cowboy action velocities?

Found the above data on IMR powder website

I have seen that page- but only see data for 38 Special. Am I missing the 357 data?

I shoot in a category called "Frontier Cartridge" where I am mandated to shoot either black powder or a "smoky" substitute. I chose Triple Seven because of the power factor (I don't like wimpy loads) and the ease of clean up and because I was given some to start out with by a hunting buddy and have just stuck with it these last few years. I do CAS for fun. I will never be a top competitor so I try to have all the fun I can.

Grayrock,
I looked again, and i guess i spoke too soon. I too only see triple 7 data for 38 special. You can still load your 357 brass to 38 special velocity without any problems.

I agree, I doubt I'll ever win a match but we win by having fun with our buddies!

As for .357 Mag data, like said above you can use the .38 Special data in .357 Magnum brass just fine. (or add a few grains to compensate for the slightly longer case)

Not sure I like going off the ranch without a map.

Triple 7 is fako black powder.
Load it up to the base of a seated bullet so there is no airspace but very little compression. Don't worry about the charge weight or "data".

There is no possible way you can put too much Triple-7 in a .357 Mag case, cause too much won't fit.

Jim Watson and rcmodel already answered that one. (and quite well I'll add)

"There is on map so you really can't worry about leaving the ranch."

You can shove that bullet down to the same place as the 38's or do as said by Jim.

Just because there is more road doesn't mean you have to drive that far. I don't know much about Triple 7 but black powder needs to have the air space filled so you can also seat longer & use filler. Corn mill works.

So the plan now is just fill 'er up and crimp 'er down! With 125grain LRNFP I figure about 20-25 grains (by volume) ought to fit with no compression. I'll see what happens! Thanks for the help.
