HP-38 for .357 mag lead cast

[thomis]

I know, I know, 2400, H110, Blue Dot, all more ideal powders for .357 mag.
However, I have a bunch of HP-38 and a bunch of Missouri Bullets .357 mag 158 grain. The Hodgdon website says
3.4 grains for 796
5 grains for 1109

If you have used HP-38 or this type of load please share your charge and results. Many thanks,

Thomis

Not for light plinking to mid-range loads with cast bullets it isn't.

Just follow the data you noted from Hodgdon and you will do fine.

You cannot load max velocity Magnum loads with HP-38, but I guess you don't want too anyway.

My favorite 357 158 LSWC plinking load is 4.5 grs. of hp-38.It is accurate and mild and fun to shoot.

I have used 4.1 gr 231 with cast 155 gr 358477. Worked fine.

Between 4 and 5 grains of W231/HP38 with those bullets would befine. It's not top speed magnum powder but it will do just fine with lead at target velocities.
