The standard for H380 is 38 grs. I believe this is how this powder got it's name.

I've been using 52 grain bullets and 38.5 gr. of H-380 for years it shoots around .350", which is good enough for groundhogging round here.
The rifle is a Ruger bull barrel with a 6.5-20x40 Leupold scope.
It's killed hundreds of hogs plus fox, coyote and PDogs Oh, and the neighbors Pit Bull.
