Re: 7MM RUM , 162 Hornady\'s & Retumbo
Call Sierra,..they will e-mail you their newest data. I find that talking to the guys there, puts you ahead of the game.
Retumbo is a funny powder,..a few of the members here have not gotten even close to max loads before pressure signs were apparant. I have loaded some for the 300RUM, but I went wayyy below max as a starting point and figure safe is always better. I'll work up from there.
You try to get closer to the target,..and I keep trying to get further away.
