[QUOTE="Shooter Fred, post: 541768, member: 31648"] Thanks Reloader...I guess I was just trying to ask if its normal to see pressure signs decrease while increasing the OAL? I am a long way from the lands as my 300 RUM has a long throat. The signs of pressure definitely decreased as there was no case that was hard to open the bolt after firing and there was no ejector marks and virtually no signs of primer flattening. Whereas when I fired the same load before there was definite signs of pressure (the only difference was a longer OAL). Also, does outside temp have anything to do with pressure signs? The temp was a good 15 degrees cooler this morning than last time I shot. Thanks, Fred [/QUOTE]
