Damnit it... I made a real inclusive post in reply to your comments, but it didnt process for whatever reason.
Sam,
Im an experienced handloader, just wondering if anyone had any proven bullet/powder combos in their recipe books that have worked well for them. I have several Im going to try, just wanted to see if someone had done the work for me.
killer,
Ive liked this round since my uncle started building custom rifles with this chamber over 20 yrs ago. It was originally designed for 600-1000yd benchrest competition. It's what the 300 Win Mag would have been, had Norma not marketed it first as the 308 Norma Magnum. Most reloading manuals dont show 30-338, but the 308 Norma load data is literally the same.
My gun is a Sako "A" action with a custom barrel built from a blank, not a previous .30 cal reamed out.
