[QUOTE="ShtrRdy, post: 2612924, member: 40852"] I realize this is an old thread but what I'm experiencing might be related to the OP's problem. I bought a used benchrest rifle off a guy recently and it has a BAT DS action. I can lift the bolt with my index finger, although it feels like there is some drag force. When I close the bolt there is more drag force than I think there should be. (There's that individual perception again) I got a firing pin removal tool and was able to remove the firing pin. Two things I noticed that don't seem right. 1. with just the bolt with firing pin removed, the bolt doesn't close on its own. I have to lightly press the bolt handle down to close the bolt. It seems the clearance between the bolt handle and the back of the action and the bolt lugs contacting the lug abutment is an interference fit. With the bolt closed or bolt handle lifted very slightly, there is no forward/backward movement. (that's good for the primary extraction though) 2. with the firing pin removal tool holding the firing pin back in the bolt shroud, when I insert the firing pin into the bolt I have moderate to heavy drag felt the last, about, 1/4" before the firing pin is all the way in. If I turn the firing pin assembly while fully inside the bolt there is some distinct resistance. The resistance is there while the firing pin retaining lugs are not having to hold it in place. It's just the firing pin assembly inserted into the bolt body. Any idea where this interference is coming from? [/QUOTE]
