[QUOTE="eshorebwhntr, post: 1269374, member: 17112"] I don't think it's dangerous or anything but I do think it could show increased pressure in certain setups. What make barrel do you have? Wondering if its cut or buttoned. I've also heard that small differences in reamer design have a big effect on pressure, performance, and case life in the SAUM and WSM cartridge families. An example, I had a 6.5x300 SAUM built back in 07-08. Always shot great for me but brass primer pockets would be gone around 4-6 shots with I believe around 55-56gr H1000. Now with the GAP 6.5 SAUM reamer design I can easily get 12+ reloads out of a case running the same velocities at around 60-60.5gr H1000 (+/- 30fps). Same redding FL dies I always used, almost the same freebore. Just a few differences in the reamer design somewhere made a huge difference. [/QUOTE]
