I agree with the above post, and would like to add,
the guys at Gunwerks. They influenced alot of guys in my area to buy 7mags and Berger 168's. And their informational Vids help alot of people get started in the fundamentals of precision shooting and reloading.
Having said that, I was just getting started in reloading and was Googling some info and clicked on this site. After reading some post I joined and the bug bit me. I never really thought about shooting past 400, now I been to 1200 yards and want to go the magic mile, but I'm not equipped,for that yet, but when I am you can bet I can get all I need to know, right here on this site.
