Just picked up a beutiful barely used 453, sorry no pictures. Barrel has been free floated, Cant wait to shoot it. Heres my ? When trying to remove the bolt, Like on my 452 FS I open the bolt pull the trigger and out comes the bolt smoothly. On this 453 when I open the bolt and try to pull the trigger there is no movement. I can wiggle the bolt out but you can tell it is dragging and is hard to get out. Like I said I got it used and did not get a manual. Is there something im doing wrong with the 453 ?
