[QUOTE="el matador, post: 1036202, member: 12193"] If you're not even sure that the bolt is harder to lift I wouldn't freak out. The brass is designed to reach it's max working pressure quite a ways before the chamber or bolt will fail. If you need tools to get the bolt open you're probably entering dangerous territory but a bit of a stiff bolt lift is nothing to lose sleep over. When working up loads I will go until I get ejector marks and/or sticky bolt lift. Then back off 1% to get my max charge for load development. Your rifle is unique so published data should only be used as a guideline. Always start lower than max published loads and work up, but don't be afraid to exceed the max load by a few % if you're not seeing pressure signs. Use increments of 1% or less. Also keep in mind that pressure will vary as you change seating depth or anything else. Fire formed brass will act differently than virgin brass. So don't assume a load will remain safe after making changes to it! Always back off a little and work back up. [/QUOTE]
