I'm trying to get some sort of comparison (purely for my own amusement) with fullbore and air rifle accuracy (or more correctly difficulty) at their optimum ranges. The only way I can think of making a worthwhile comparison is by looking at what is considered good group for a selection of fullbore rounds at different ranges in terms of MOA.

For example I can shoot a sub MOA 5 shot group at 25yds with my .177 MK4 (conditions permitting!) and 1.5 MOA at 50yds (I'm sure the AA shooters could do better)

So what sort of MOA groups could a good fullbore shooter expect? My days of shooting 7.62 & .303 were rather restricted to figure 11 & 12 rather than grouping so I'm not really up to speed!

Cheers.
