[QUOTE="CONatureBoy, post: 2347097, member: 118769"] I just got my 300 RUM (1:9 twist, 27" Krieger barrel) back from Gunsmith at Large in Denver (blueprint/rebarrel/Cerakote job). [ATTACH type="full" alt="300_rum.png"]314181[/ATTACH] I measured my COALs for the Berger 230 OTM, Hornady 230 A-Tip, and Berger 210 VLDH. Then I used QuickLoad to calculate the max powder charge and muzzle velocity for LRT and N568, assuming I loaded 0.003" off the COAL across the board. At max safe load N568 was 30 fps slower than LRT (2,930 fps vs 2,900 fps) for the 230s, and 23 fps slower for the 210. This leads me to believe that N568 is at its best with heavy-for-caliber bullets in large magnum cases like the 300 RUM, 300 PRC, 30-378 Weatherby, 338 Edge, and 338 Lapua. I'll develop loads this weekend, and will report what I find here. [/QUOTE]
