Hello everyone I am finally back home and can't wait to start loading for my 30-30. I have a couiple of questions though and am hoping that someone can help me out. Since I made up some some loads last year prior to deploying I have read that W 748 is temp sensitive I was wondering to what degree, also I am using Speer data which calls for a Magnum rifle primer which I am also using. Do I really need that magnum primer ? and will I experience high pressures with this powder in hot weather? if so what is a good alternative that some of you use that is not temp sensitive? Any and all advice is welcome thanks.
