IMHO I really see the 3006 as a mini magnum...and most that have shot it prone out of a bolt gun will go...yea...I could see that.
3006 is a fantastic cartridge, I own several things in that flavor, however my interests tend to drift off to the road less traveled....so I do tend to like the odd ducks.
I will stick with my statement that no matter the cartridge, and if it is tossing a 308, 311, bullet as long as the gun is in like shape....and I guess I should say class as well the results are going to be about the same.
I really don't think you are going to see the guns shooting one over the other being any different (enough different to worry about), now if you toss in 243, or some other flavors then yea there are going to be pluses and minus to each flavor...but in my book 308 vs. 311...and really I see that as what we are talking about here....not enough difference to worry about.
