[QUOTE="woods, post: 872952, member: 6042"] You might try a seating depth test, especially with the Berger I did a test with a 6.5 rem mag, 130 gr SSII's and RL17 and the results were Distance off lands / Average fps / Extreme spread / Standard Deviation .015" / 3209 fps / 31 fps / 11.67 fps .030" / 3200 fps / 32 fps / 11.70 fps .045" / 3186 fps / 23 fps / 9.80 fps .060" / 3176 fps / 8 fps / 4 fps .075" / 3170 fps / 27 fps / 11.4 fps .090" / 3156 fps / 52 fps / 31.7 fps I think Berger even has a seating depth test they recommend and it is posted around here somewhere. Results were sometimes Bergers like being way off the lands But my point is you might find a sweet spot that is much further off than your .020" BTW I have the Pro Chrono and have no problem with it [/QUOTE]
