[QUOTE="Joel Russo, post: 298376, member: 6152"] You need to know what your chamber neck dimensions are! Call the guy that chambered it, and ask him. After you find out what it is, you can then turn your necks to give you the proper clearance when you chamber a round. Usually .003"- .004". If you have a bushing die, you can then adjust neck tension by changing bushings. Then do your load development by measuring case stretch over a virgin piece of brass. This will tell you when you are approaching your max load way before you get to the "heavy bolt lift" or extractor marks. Standard loads are not standard in all rifles, you may have an extremely tight bore.. thus coming upon max load before the advertised max load. You don't mention where you are seating the bullet in relation to the lands. Keep in mind that the closer to the lands you go, the more pressure you will encounter. [/QUOTE]
