[QUOTE=".284, post: 1072556, member: 19604"] Never ran into that yet. Any chance it's the shoulder of the modified case? Do you have a full length bushing die or body die to bump it before trying any thing else? If not I guess you'll have to neck turn the modified case but I suspect you may need to size it down a bit so that it's tight on the turning mandrel? Try to fit it on the mandrel first to see if there is too much slop because it may become a little tight to push the bullet up into the lands afterwards unless you have a way to slightly expand it a again. Or inside neck turn it afterwards. Other option would be to neck turn a case fairly thin, then load and fire it and thread it for the oal gauge. Or load a bunch of dummies up at progressively longer oal's and measure them before and after chambering to see when closing the bolt pushes the bullet back into the case. You could also carefully measure the difference in length between a cleaning rod that touches a closed bolt face and one that touches a jammed bullet but this would be my last choice as it's not generally very precise and would not give distance to the lands from the ogive. You would have to measure oal from the tip which is not the right way to measure seating depth. That must be an awfully tight neck though? [/QUOTE]
