I shot with this during my first time at Perry at the SAFS. Never shot past 100yds before going that week. Only shot 2 matches ever before going also, 1 of those was the week before Perry at my local reduced range. I was a noob of the highest order. I didn't even have a spotting scope. This thing rattled so bad I thought it was going to fall apart on me. As long as the barrel isn't shot out, I'd run it.
I ended up 3 points from a bronze medal in the EIC match after SAFS with it. I also was 3 points from a bronze (again w/o the use of a spotting scope) during the JCG match.
During the JCG match when I walked up to the line I asked the guy shooting a Garand next to me what dope he was using and copied that for my rifle. I'm scared to go back because I know I won't have beginners luck this time.
This is the rattle trip I used during the EIC match.
I shot the rest of CMP week with my Service Grade SA from the CMP
