[QUOTE="Buttermilk, post: 3021157, member: 5262"] I shoot a lot of short barrels. I've been primarily a handgun hunter since 1993. In most cases, the same powder that gives the fastest velocity in rifle barrels also gives the fastest velocity in shorter barrels. There are exceptions to this, but generally speaking, that's the rule. I shoot or have shot several big cases such as 30 Nosler, 7 SAUM, 30-338WM, 7RM, 30-06 JDJ, 30-30AI, 280AI, all in short barrels, 14"-19" in length. If you've ever seen a pressure trace of a round being fired, most traces show the powder is burned within the first 3 inches or so of barrel length. Longer barrels allow for more efficient use of the gas volume and thus higher velocity. I'd say you have seen a pressure peak with SB6.5 that's higher than the pressure peak of RL26, and thus higher velocity. [/QUOTE]
