once I get my .260 up I plan on giving it a try (long action build so seated long roughly same useable capacity as a .260ai at short action mag length). I've read that it has a very high load density so you can fit a shit ton in the case. also reading that its not as bad as the older reloders with temp sensitivity.

i'm thinking it will yield more velocity and possibly more barrel life. kind of like what people are doing with the 6.5 saum 4s with H1000. their using slower powders in longer barrels to keep pressure down and doubling barrel life in the process.
