This is very interesting. Everything counts! My Remmy 300WM has been a Sub-MOA gun. But just barely. Not like my 308, 1/2 inch gun but I have Lapu poo in 308. I just bought some Norma to try in my 300WM.

Going to try some magnum match tonight, and hopefully my Lapua brass will show up today. I'm going to shoot an F-TR match this weekend, so here's where the rubber will meet the road.
ETA:thank you for finding that!
ETA again... OnTarget is kind of useful.

Finally got to the range and shot my new A3G the first time a few weeks ago. First time in my life shooting a bolt action other than an old bolt action .22 when I was a kid.
Took about 5 shots to get on the center diamond then I shot a three shot group to see how it grouped.
This was that first 3 shot group @ 100 yards. Haven't measured it but I'm guessing it's 1/3 MOA?

I shot one more 3 shot group that was close to as tight as this one then it started to rain.
Looking forward to going back to the range the weekend to finish sighting her in.
