By looking at recoil calculators, it seems that the 35 Whelen has just as much recoil as the 300 Win Mag because of the heavier bullets, and the BC is a good bit lower on the fat bullets. I think that I will stick to the .30 caliber stuff.
I handload, so I can load down the .300, but it still uses so much more powder on .30-06 duplicate loads that it makes me pause (money and recoil). Also, some rifles do not respond well to reduced loads. I wonder about the .300 WSM as a "tweener"???? I will have to look it up. Also, how does magnum brass hold up compared to .06 brass?
I am just wondering if anything really needs more than a .30-06 with a premium 180gr bullet at the ranges that I will be hunting. I am not too macho to admit that I am becoming more recoil sensitive as I get older (construction work has been rough on my body), and I can shoot more and more accurately with a lower recoiling rifle. I cannot shoot well enough, regardless, to take a shot over 250 on a deer, and 350 on a larger bodied animal with a bigger kill zone.
