[QUOTE="PrecisionRifleBlog, post: 824894, member: 69537"] That is definitely one of my best groups. My average group size is 0.25-0.30" with that load, with 25% being slightly smaller that average (down to the .18" group shown), 50% being within that range, and 25% being slightly larger than average. Here are some of the stats from my groups: mean = 0.274", median = 0.265", standard deviation = 0.062". The rifle/ammo could probably do better if I was better at doing my part! I definitely can't blame a miss on the rifle anymore. It has to be the nut behind the gun. What made the group in that photo so impressive to me is that it was my very 1st three shot group I fired out of that rifle with my "match grade" handloads. No joke. I had fired about 25 rounds down the rifle to break-in the barrel, then that was the 1st three shot group when I started doing serious load development. Might have been luck, but I was still proud of it. I hope that helps answer your question. My barrel has continued to speed up as I've shot it in, and I ended up backing off this load to 69.4gr of Retumbo and still maintained good velocities (3140 fps out a 27" barrel). [/QUOTE]
