Last night, I needed some plinking loads for today, but didn't have much Varget (reserved for 5.56 service rifle).
I had a pound of H4198 - "too fast" and 3lbs of H4831 - "too slow". I couldn't find data for 4198 and 150gr bullets, and very little for 4831 and 190gr bullets.
What I did find suggested a minimum of 45gr and a max of 50gr with 35k CUP and ~83% burn. Given that there was some data, and a case full of H4831 is less likely to kaboom, I chose it.
I was going to use 48gr, but it was halfway up the neck and probably would've deformed the bullet upon compression to desired depth.
Rifle:
Vz24 Mauser with 22" M1919 barrel chambered in .308 Palma 95 (basically SAAMI min.)
Load:
Hornady 190gr BTSP
46gr H4831 (settles just below neck)
RP case
Winchester LR primer
2.800" (just into lands). Compressed a bit.
Avg velocity: 2223fps
Extreme spread: 66fps
Standard deviation: 19fps
Case necks get rather dirty.
Not an ideal load, but not too shabby.
I'm about to clean the rifle and will update soon
TM with notes, and get pics of the cases.
Hopefully this satisfies anyone's curiosity.
I pulled the last shot left. 9 shots would fit comfortably inside the 1.35" X-ring at 100yds.

Another 10 shots.
