[QUOTE="BillyGoatGruff, post: 2460227, member: 63346"] New questions, Thought of start here vs starting a whole new thread. 1st. Repeated the upper end of my previous pressure test. 1st run had slight pressure signs at 69gr no pressure sings at 68.5gr. Started new test at 68.4, then had a .6 and a .8 loaded. Had pressure sings at 68.4 this time around. Cause of why it started at a different charge weight this time around? Same brass, bullet, powder and cbto length. Only difference is I cleaned the rifle. But the rifle was also clean before previous test #2 Seating depth test. The best two groups had straight vertical stringing. The rest were typical triangle shapes but pretty open groups. What causes vertical stringing? [/QUOTE]
