[QUOTE="Mysticplayer, post: 23052, member: 8947"] Had a similar problem and this is how I checked. 1) look at the area of the case just in front of the belt. If this has expanded to the same diameter of the belt then this could be your problem. Loads are too hot for the brass you are using. One of those collet belt resizers is in order. The FL die will not size this area adequately. 2) try to rechamber the fire formed, neck sized brass. If it does not go in, rotate the brass and try again. Continue to do this and if the brass does chamber, mark the orientation and try another case. If this is a commom problem then the chamber is not square with the bolt face. The best solution will be to resize in a FL die. Resize just enough so that the bolt firms up just as it closes. This should not affect accuracy but could lead to shorter case life. 3) if the case does not go in because it is now too long (not because it is bent), you are probably running high pressures or the headspace is too big. Look for a shiny ring near the belt. You can use a body die or partial size with the full length die just enough to bump the shoulder back a smidge. Many times chambers are cut on the small side for target work and any case growth can lead to stiff chambering. I am guessing that the case length is within specs and that the bullet is not jamming into the lands. Let me know how it turns out... Jerry [/QUOTE]
