New to 357mag reloading

[downtown]

I'm getting ready to start reloading 357mag for a carbine rifle. I've got some Magnus 158gr JSP's (J-119) and I'll be using H110. Hodgdon's data shows that with a Hornady 158gr XTP the starting load is 15gr and max is 16.7 at COL of 1.580. I think I'll follow this being that it's the closest data to the Magnus bullet I can find. Does anyone load Magnus bullets? All advice welcome. Thanks. Her's a pic of the XTP and the Magnus J-119.

No, I've never tried the Magnus. I've heard good things though. I have loaded Hornady, Sierra, and Remington in jacketed and they are all good. I've mostly loaded cast in .357 Mag. H110 is a great powder for .357, and so is 2400 and IMR 4227.  My favorite has always been 2400. Good luck with your loading.

I use the 158 gr hp bullet  from the zero bullet  company.  Also I used the 125 and 158 gr extreme  plated bullet.  Powders used are sr 4756 and titegroup.  I currently  use the 158 gr hp with 6.5 grs of titegroup  in a marlin  1894cb for pistol cartridge  silhouette  matches.  Back in the 80's I used h110/2400 in the 357 mag but for silhouette  shooting  there was better powders that group better and had no kick.  Now if I load the 180 gr sierra 357 mag bullet  I use h110 to get the speed  to knock down the 200 meters rams in the big bore game.
