[QUOTE="Crockett12, post: 741533, member: 35100"] I just did a comparison of a bunch of loading manuals that have data for H-450 in the 270 Win and the 270 Wea Mag. – none of which have any data for the 270WSM. Anyway -- I compared data from 8 of my older manuals (including the Hodgdon #26)-- and you were right that H-450 is very similar to H4831 -- more than any other powder that was in all those manuals. In most of them, H-450 started with the same Min load as H4831 in both cartridges – and ended with the same Max load too – or within 1 grain of the same Min and Max! The Min and Max velocities for both powders were similar too! So I’ll use the H4831 data and watch for signs of pressure. Thanks for the answers! Crockett12 [/QUOTE]
