I have a couple of each and keep telling myself the '06 makes more sense. On the other hand, I spend more time with the H&H's - this one often leaves me shaking my head considering it's age and rather rough stock.
...and that's all I have to say about that
JGray over the years,I have owned 3 pre 64 300H&H's. All three would shoot like yours, and our club VP pestered me to sell him mine after he saw it shot at 600 yards.
I guess Winchester barrels were generally just "good" and it's a riot they shoot so well....the bedding looks like nothing to write home about,but hey shoot nevertheless.
