    Hello everyone, I've been looking for load data for this round using Hodgdon Varget. I havn't really found any great data so I decided to find something close to the same weight with a flat base. I plan to use that data and work up looking for pressure signs. The funny thing is my Nosler Reloading #6 says the max load for the 60 grain Partition is 24.5. All other data from 62grains up to 69grains have a max load of around 26grains. These are flat based bullets and boat tail. Is there something about the Partition that makes it build more pressure? Also has anyone else loaded this bullet with either the Varget or H335. I'm loading for a 1:8 twist AR 15 with an 18" barrel. (Rock River Arms ATH Carbine)

    Try looking at the Sierra 63gr loads for Varget and .223. Max is 26.4gr.

    I've not used 64gr Win PP, but loaded baker's dozen variety in .223(36,40,50,52,55(several),60,63,75,77) and Varget and working up from 24gr to 26gr in .5gr or .3gr increments should find a good load.

    Thanks ForneyRider, Don't you think it strange that the max load for the Nosler is 24.5 grains?
