Recoil is always an issue and a little bit less is a little bit better.
You can illustrate this by going with a LOT less.
Take the average guy out with a .223 and a 45-70 and see if he doesn't make much smaller groups with the .223 and much larger groups with the 45-70.
That's just the way it works. Recoil is always the enemy of accuracy.
I will not totally disagree, but my last range session saw me putting up smaller groups with my Mod70 300WM than I was with my Ruger 77 in 223. Both were shooting well under an inch. Of course I burn more than a few rounds each week.
