[QUOTE="HiTechRob, post: 851136, member: 71328"] Check your COAL. I think you are running the bullet up against the lands. That can cause a pressure spike if you do not give the bullet a little room to jump onto the lands. You want to minimize that jump for accuracy, but you want to have the bullet seated just off the lands. It will be different for every bullet/cartridge combo. I then back off 0.10" to get my seating depth. If it is difficult to open the bolt after firing, this can be an issue. If the powder measures are within spec and you are using new brass and full-length sized it or fired brass that has only been used once or twice and neck sized it properly, you should not see pressure problems if starting at low end of powder. Hope that helps! [/QUOTE]
