I finally stepped the Savage 110 FCP .300 Winmag out to 500yds Wednesday. It went a little better than expected. I currently have a Konus M30 8.5-32x52 scope on it, hope to upgrade glass after getting a few projects done. I was shooting Hornady and GA Arms 180gr ballistic tip. After checking zero at 100yd, then 3 rds at 200 to see if my calculations were close, I headed on out to 500.
There was a bit of wind, but all in all I'm pretty happy with the results of the first six rounds.
I then fired the remaining 14 rounds I had, the entire group stayed about the same. Honestly, the rifle still shoots much better than me. I plan on getting much more long range practice.
