I too have found great accuracy with my RRA predator model with 20" barrel. It shoots the 40's very well, but I switched to a 69 match king instead for those longer shots in the wind.

But my go to rifle will always be a 243 rifle though, even with saving hides.

Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no hope at all.
