Don't matter how good a shooter one is, if the equipment is only good for .2's and .3's, you ain't hittin' .1's on the regular
Much as we love to pretend our factory rifles are laser beams "if we do our part", they aren't, and they limit your potential. An exceptional factory rifle may produce .1's and .2's as an average, but usually if you seek such accuracy, custom builds with match chambers, tuners, and lot tested ammo are required. These are physical equipment limiters that no amount of shooter skill can overcome, you must have capable equipment to achieve such performance. Anschütz cuts a great chamber for a factory rifle, but Lilja Match, EPS Match, and custom gunsmith designs are yet another step above.
Shooters of a certain skill level certainly will be held back by the average Anschütz factory rifle.
I don't feel like I've shot a rifle yet that wasn't holding me back to a degree. We must remember the .22LR cartridge we cherish so dearly is fraught with inherent accuracy issues that centerfire shooters would have no patience for. They laugh at our 1/2" at 50 yard challenge saying "we do 1/4" at 100".
