Post by wrenchman » 04 Mar 2020, 10:28 am

worked upsome more test loads today for the 357 with speer bullets and h110 powder i loaded up 25 125 grain hollow point and 25 158 grain flat point.
This is the first time with this powder and these bullets so i am learning something new it is a rather fine powder.

What gun are you shooting them out of? A rifle?

For a ball powder, I like lilgun because it gives the same velocities at lower pressures. It's therefore inherently safer i.e. case capacity will be your limiting factor (instead of pressure). Although to be fair there's talk lilgun "eroding forcing cones" on revolvers - something I'm not familiar with (don't shoot handgun).

I did some H110 loads last year to use up some powder I didn't like from 300 Blackout and it worked fine in 357 Magnum. I think next time I load 357 I am going to try IMR 4227 which has worked well so far in 300 Blackout.

I might be wrong, but from watching yanky youtube videos IMR 4227 looks very similar to ADI AR2205 - it seems to be a stick powder of a very similar density. And while it's listed as "equivalent" to H4227 / H110, those are both ball powders, so fundementally different.

And in my experience stick powders give you better std-devs compared with ball. Does this translate to tighter groups? Not necessarily, it's just a variable. In some cases loads with higher std-devs group tighter :lol: go figure
