H110 - 357 mag - 158 grain JHP - I'm at 18 grains
- Thread starter black_hog_down
- Start date
Gigantic pictures aside, 16 grains of H110 is .7 below MAX for a jacketed 158 grain rifle load. As daft as it sounds, 2 grains isn't that far over max. A different powder lot, test conditions, rifling twist and a bunch of other variables will change the max load.
A chronograph won't help or make any difference.
"...could maybe hide..." Nope. Velocities don't mean a lot as you're not using the exact same components as Hodgdon did. Pressures
"...what they really mean is..." Pistol calibres. Nothing crazier than hunting regs, anywhere. In parts of Ontario, you'd be arrested for using a .357.
Salmoneye's jug is a different powder lot than what was used by Hodgdon or anybody else. Half a grain more now gives 163 fps more velocity with a below current max load.

You've already found your load. You stated that you noticed no differed from 16-18gr. Sounds like a node to me, so load in the middle at 17 and you should be good to go.
H110 / 296 is one of those powders that seems to reach a plateau in velocity.
You get to "X" velocity, and any extra powder is burned outside of the barrel... IE, NO or little velocity gain.
That said.... It is not safe to exceed manufacturers data.
Those same overloaded rounds.. when left in the sun, or with a bullet setback... could easily skyrocket in pressure... it is just not worth it.
If you had a pressure failure... and lost an eye or such. ( God forbid ).. you would never forgive yourself.
