Thread: 3 shot groups are useless!

Some further interesting results. Shot today in nice conditions. A different rifle, newly assembled using a Zermatt arms Origin action, a Savage 223 barrel reamed to 22 Creedmoor by Greg at Custom guns and the result shoehorned into a Bregara stock - this is a work in progress!

I'd already tried the barrel in a Savage action enough to establish a safe max load and to get the feeling it was a pretty good shooter.

Load is 75 gn Hornady ELDMs in front of 2209 in reformed Norma y.5 CM cases.

The rifle was zeroed with some old rounds then after quite a lengthy period a 3 shot group was fired


Not too bad eh?

So left rifle to cool then fired a further 3 shot group on top of the old one. Came out like this



Process repeated with this final result


Not to shabby.

But what is the big picture here


So a overall group of the tiniest smidge over MOA. But whats mist important? To me its the variabce in POI of each 3 shot group, proving out Gimps assertion (in his other thread) that zeroing on the basis ov a 3 shot group is a faught exercise!
