If you have seen some other posts here, many people have said the short barrel model
Rugers do not shoot all that well. They have to bed them first.
The target model Rugers with the laminated stocks do better.
I have one of those, and 1 inch groups @ 100 yards are no problem
with a couple of different loads.
Having said that, the CZs have a real good reputation for accuracy in many
calibers. ( Even in .416 Rigby )
