This mold just showed up on a Midway sale flyer so I have one coming to try. Just playing around with Quickload leads me to Lil'gun and 296, (as usual), and it looks like 1900 fps + should be easily obtainable with a COAL of 2.250 in Hornady brass. There is a caveat on using data interchangably between cast boolits and jacketed bullets, and that is bullet shape. It is possible to have significantly different case capacities at the same COAL. Spitzers, (typical for a jacketed rifle bullet), are commonly seated much deeper into the case than a cast boolit of the same weight, (often round nose flat points which carry more weight in the nose, outside of the case). In this case you'd be extrapolating in the safe direction, but that's not always going to be true.
This bullet appears to have more bearing surface than the 300 grainer I designed, so I have some hope for better accuracy. It is also in the Quickload data base which should make it easier to come up with accurate pressure estimates.
Unfortunately this is another Saturday at work, when I should be home putting my reloading room together
