Great group RockChucker!! Excellant! On the topic guys, one quick question. How does everyone usually measure a group size? Outside to outside of the bullet holes or center to center? I've always gone center to center but after the picture, I was wondering what the commom practice is.RockChucker said:The weather finally broke! -10c and a moderate breeze 15kph
Almost perfect for shooting groups. The Ruger #1 is no longer a virgin, average groups were sub MOA @ 100mtrs using H4350 and Speer 270gr bullets. Had a notable last group prior to packing up and heading for a hot cup of coffee!
I'm not saying that she will shoot like this all the time but pretty close to it.
Avg. velocity was 2465FPS and the cases literaly drop out of the chamber.
Thanks guy. In reality and with the same degree of accuracy, either ends up being the same thing for the most part. Again, nice group.RockChucker said:Yes, proper way is to measure outside to outside and subtract one caliber. Figured I would leave the math up to who ever feels that they just have to know to the .0001" My only concern is where the first bullet hits out of a cold barrel. The rest of the group is just icing on the cake!
