If you have a "true" half-inch gun......not one that has shot an occational good group......I'd not do anything to change things. Hell, I'd be hesitant to even clean it agressively.
Those rifles are a lot more rare than you might think from reading the internet......and I mean consistant half-inch groups, not the best it's ever shot. Anything (bedding, muzzle breaks, new scope mounts, or just tightening the screws differently) can effect this "perfect" balance and should not be risked.
In general, I don't buy into the recoil objections. I do know from talking to others that I apparently don't feel the effect of recoil like some, but rifles less than the truely big boomers (.458 and above) just aren't that harsh. Doesn't mean I look forward to shooting 40 rounds from a bench with a .375 H&H, but it IS tolerable......particularly for the small amout of rounds you will fire in the field.
