I am thinking about experimenting with Reloader 22 in my 300 Win. Mag. shooting 212 ELD-X's and would like to know if anyone would have a good idea as to where to start loading up from? Most material I found online showed loads with 71-73 grains in the heavier bullet weights similar to mine so I'm guessing I should start around 68-69 grains just as a safety precaution? I currently am using H1000 and have never worked with any of the Alliant Powders.
