What exactly is a MOA rifle??

An example that appears reasonably frequently online to demonstrate this underlines my aversion to 3-shot groups: a 3-shot group gives you 95% confidence that future shots won't impact outside a circle about 3 times bigger than that single group. So if a rifle shoots a single 3-shot 1 MOA group does that make it a 1 MOA rifle or a 3 MOA rifle ?

Which is why you use the results of multiple lower shot count groups from a barrel that is not intended for long strings of shots, as has been pointed out a number of times. There is absolutely no point going nuts and finding out the 'accuracy' if the result of finding out means it is no longer accurate. That would be about as useful as crash testing to destruction every car off the production line.

jeesh...all this technical stuff. & I thought it was a musket that the natives used for hunting moa ?

MOA is less granular. 1 Mil is 10mm at 100m, compared to 1/4MOA at about 7mm.

To me the actual units mean diddly squat, the conversion is easy enough.

Yards sounds further.

But it isn't.

got a shoot just shy of 110 yards to shoot 100 Metres

I prefer yards & MOA, a finer measurement is obviously more accurate :thumbsup:
