[QUOTE="Veteran, post: 2592936, member: 118038"] I would say N568 would be a closer replica to IMR 8133 because they have identical burn rates of 0.30. N570 is slower at 0.27 You can probably get more velocity out of N570 because it is slower though. N568 may be like IMR 8133 more temp stable though than N570. Id run your load, barrel length and bullet through QL to compare. I would not just assume you can start w equal grains of N570 to 8133. 2 very different powders. N570 is double base. [/QUOTE]
