That's also been my experience: If the bedding block is straight and square.
Recently dropped the barreled action of my Remington 700 .204 into a Stocky's bedding-block stock. The rifle was already very accurate in an epoxy-bedded factory stock, but shot noticeably better after simply bolting it into the new stock.
Thats not the norm. An aluminum bedding block will never be absolutely perfect. Thats why most will skim bed the action to the aluminum bedding block. You got damn lucky. Im thinking whoever glass bedded the first stock fu cked it up by inducing stress to the receiver. A properly glass bedded stock would have generally out shot a straight up aluminum bedding block stock, that was not skim bedded to that receiver.
