Trying to adjust the accutrigger on my Savage 11/111 Trophy Hunter XP in 260 remington (19682).

OEM trigger was set to 3lb 3.5oz. I used the adjustment tool to back it out as far as I could. The spring crossbar jams up against a hard stop and won't let me go lower than 2lb 14oz no matter how hard I turn it. If I turn it any harder I'm going to snap the toolhead off.

This is baffling me, because my Savage 10 FCP-K came out of the box with the OEM trigger set at 2lb 6.5oz.
