Yes I do. I began using my doubles for my "regular" hunting just to learn about them. As a result they have become my favorite hunting rifles. If I could have only one hunting rifle for the world I would have a scope fitted with claw mounts for my 450/400 3 1/4". I would use 300gr Hawks with the .025jkt for all deer/sheep etc. sized game and 400gr Woodleigh Softs [and solids where appro] for everything else.
If a fella only hunted North America my 9,3 Chapuis would do it all.
