Murf,
That's good shooting with the mag, I've found very few that like any of the ammo I've had my hands on, a MOA at 100 has been a challenge with this stuff so I seldom spend any time with them.
We had a fairly calm day today (10 mph or less) and the temp made it to 50° F so excluding the mud it was an excellent afternoon at the range. I spent 4 hours of quality time with the LabRadar and the ugly Ballard. Just like the indoor targets indicated, this thing favors Norma Match and the trials included both more and less expensive brands. They weren't dime size groups but here's a sample of an average for both a 100 and a 200 y group (had a couple groups a little better at both distances but these groups tell a story. The 200 shown had a terrific vertical string but the wind had shifted from a left to right to a straight on gusting breeze when I moved back... if I'd put a scope on old ugly, these 60 year old eyes would work less - just can't surrender to glass yet.
