Continuing the shots per group ratio

[Ribbonstone]

Am thinking the progression of shots oper-group vs group size satays pretty much proportional.


Yep....more shots per group,the larger the group, but it seems to grow proportionally when the air rifle is stable.  If it doesn't grow proportionally, I'd suspect some kind of instability in the system.


Then larger the fitsm 5 or 10 shots,the larger the final 20 sbhot group,


Which makes sense,,,it's pretty much well predicted in the literaturen (considering on-line sources as "literature").


So this single .177 5 shot effort (known accurate,"match rifle"accuracy):

Grows into this 20 ashot effort (yeah...one out of 20 is a "bad boy".

This .22 sporter  5-shot effort:

Growns into this cluster  at 20 shots.

BUT...the proportion strays about the same.
