So I followed the instructions from Berger (also found on this forum) and performed the seating depth test. I didn't do the 6 rounds of each like they mentioned but only done 3 rounds of each. The results were shocking to say the least but I think I found my best COAL. Shooting a Savage 111 LRH 6.5-284 norma. Scoped with a Weaver Tactical 4-20x50. Currently shooting Nosler Brass, 52 grains H4831SC, CCI 250 Magnum primers, Berger 140 VLD Hunting @ 2775 fps. I have some retumbo that I plan to work on a load to attempt to get more fps. I'm pretty pleased with the results so far.
