I have given this one a lot of thought. I've not had an 06 drilling, but have one in 7x65 and 8x57 as well as in 9.3x74. If I only had one, and did for a number of years, I'd have the 9.3. In a drilling, you can load it down a bit or load with cast bullets and have a great 150 yard whitetail rifle with your shotgun. With factory loads, you will have a nice medium bore that will work for moose, elk, bear or Africa. I've found 9.3x74's in most well stocked gun shops or available on order,except for the last while when nothing is available. I use mine in all kinds of weather and for all kinds of hunting. I've put Einstecklauf's in mine to use 22 WRM in the right barrel. just my thoughts.
