I think what he's getting at is saying you can hit a sub-1/2MOA target at 1000yds with implied regularity...>50%? exceeds the performance of purpose-built target rifles on purpose-built rests shot by shooters who specialize in doing exactly that. Fine if you hit them once in awhile, but claiming a factory rifle would hit a clay >50% of the time, over a significant number of shots, likely from a bipod or sandbag, at 1000yds simply defies belief.I've never competed before, but it's just a stock Savage M10. The load I'm shooting is I worked from 45.5 grains to 46.0. The largest group it shot was .475.
I'm being honest in what the gun can do. It may make a lier out of me tomorrow, but I have witnesses and video showing some of the shots. I'll try to put the target from working the loads here.
I'd look at what bullets have the lowest expansion velocity in the 500-700 yard range. I don't know which ones but there are some. At ranges beyond that, if you care about the expansion envelope of the bullet (and you should), you will likely be looking for a bigger chambering.
