I am also a fan of Single Shots
I have a Ruger No 1 International(manlicher stock version) in 30-06. I too like short and handy Rifles. The only problem is that when the chamber is empty they are truely empty. Getting them into action takes longer than just working the action on a bolt action with rounds in the magazine. I used to worry about the slow second shot on a Single shot rifle, but I finally learned that you just need to make the first shot your only shot required.
