I think I have been a member for a month or so, mostly lurking around ( New to anything like a forum based site). This is an incredible resource! All my training has been 500 Known distance and reloading for hunting. I’m the guy Frank is Referring to as not leaving the 100 yard range . Found a local range with 1000 yards and I have to qualify to shoot to 600 and beyond. So far all have been very professional and helpful with questions. Look forward to the education.SF brothers
