[QUOTE="fiftybmg, post: 1772085, member: 96316"] Your first and only source for reliable load data is the loading manual. What other people say they do is not reliable load data. If the bullet is not in the manual yet, you can start low with another bullet of the same weight, and work it up. The barrel length has nothing to do with the pressure safety of the load. It does affect the muzzle velocity, so for the information to be specific for a 26" barrel just means you should not expect to get the same velocity from your 24" barrel, you will get less. The secondary pressure spike people speak of was discovered in the post-mortem analysis of a small quanitity of slow burning powder in a large case that blows the rifle up into little bits. Loads that are reduced tend to show the beginnings of that secondary spike. [/QUOTE]
