300WM with RL22 for 178 grain ELD X

[paulbshooting]

Hello, planning to load up some 178 grain ELD X for the 300 WIN. Have plenty of RL22. Anyone got a proven load. Starting from basics and suspect around 73.0 grains will be good. Thanks

If it were me I'd start with the 175gr data and go from there...or risk my face by using some random guys load data from the Internet

Thanks. Have the 180 grain data from the nosler and older hornady book so will be starting low and working up. Just interested to see what others found worked so I maybe can save some components. 180 grain accubonds shot well at 73.0 grains but different bullet eldx.

Thanks @caberslash That wasn't in my 9th edition hornady book and could not get the app purchase to work to buy that. Most helpful.

Keep in mind the COAL for all belted magnums is super-short in the Hornady books due to them taking auto loader into consideration.

The US Military were using 300 WM with 190 grain Sierra Matchkings going over 3k fps... not to SAAMI spec!
