I always bench my rifles when I first get them, both to zero the sights and to try different ammo setups to see what the potential is for the gun's accuracy. Then when I'm shooting off-hand or semi supported, I can tell just how bad I am and know it's not the gun, it's the trigger puller.
The bench only shooters are enjoying the sport in their own way and that's fine with me. I have a fine Remington 700 PSS that was worked over by a master gunsmith in my area, and with my handloads is a one ragged hole maker...on the bench. Off hand, well, let's say it gets heavy in a hurry and the barrel gets hot and the humidity is too high and it wanders a bit.
The beautiful thing about our sport is that it does offer many facets to pursue and much enjoyment to be had for anyone that wants to learn different disciplines.
