IMO, yes......it's too big, unless it's got a brake on it.
I don't deal with recoil very well, and I like to shoot alot of rounds in a day. I don't enjoy having the snot knocked out of my nose every time I pull the trigger. Hell, even a heavy barrel 25-06 will bruise a collar bone after 100 rounds in a prarie dog town.
I think it's hard enough for new shooters to get in the groove and enjoy the experience without adding pain to the equation.
My grandfather used to shoot competition for the military and he said "A 243 or 308 or 30-06 is all the gun a guy needs, I've seen alot of good shooters ruined by those 7mm and 300 maggies!"
