[QUOTE="JARHEAD1371, post: 2068739, member: 12950"] Update and lesson learned: Last week I posted a couple pics during load development for my new 25 SST. This morning I shot to fine tune seating depth and had great results. Conditions were perfect, 40 degrees and dead calm. The first pic shows the first 5 shots, all seated 5 thou off the lands. I don't shoot very fast, maybe one per min. But shots 4 and 5 seem to always open up dramatically. After waiting about 15 min, I shot 5 more at 18 thou off. Same results with 4 and 5. It finally dawned on me that it has happened before. I always keep good notes of each shot and my notebook confirmed. I waited another 15 min and shot 2 more (18 thou) and that group is pic 2. The 7th shot broke about 1/4" low (my fault, just excited to see the result). This is my first carbon wrapped barrel. Is it common for them to open after just a few shots? [/QUOTE]
