Similarly a .325" group at 54 yards : .325/(.54x1.047) represents .575 moa.

This can be handled by a little solar powered pocket calculator with basic arithmetic functions.
Yes, its simple basic math. Saying a rifle is a .57 moa rifle is exactly what I said in my previous post. Look at some of the targets I post. Most are labeled with the moa. It doesn't matter if I'm shooting 100 or 1,000 yards. The group size is labeled. I guarantee if bugger shoots 3 5 shot groups side by side on the same piece of paper, the average is not going to be exactly .57 moa every time. Also most guys use an average of 5 5 shot groups, or if either of you have balls enough, you can shoot the moa all day long challenge here. That will show that it is likely not a ".57 moa" rifle. The number stated is arbitrary, like I said.
