Reloading Question

[Culvercreek hunt club]

OK...I have all my stuff. I hav read and reread a reloading manual.Researched components and I am ready to go.

I am loading 38+p and 357 pistol ammo to start.

I have new and once fired brass

Small pistol primers---check

Unique Powder---check (buddy recmoomended it)

Now here is the question. The manual doesn't have load data for a 125 gr JHP with Unique. The Alliant site however does. But is specifically calls out Speer GDHP (which is a jacketed hollow point)

9.6 grains of Unique (max load)

When I am looking at this data....are all JHP's a JHP? LOL I am thinking Alliant and Speer are tied together so that is why it is listed that way.

If I back down 10% for a starting load on this I shouldn't have an issue? right?

before someone asks I wanted the 158 gr but the 125's were on sale for 1/2 the price of the 158's
