The CFE, is listed at 108% full at max. 31.0... That's too compressed for my money. Although once upon a time I did load some AB's with CFE at about 30.6, again for a howa. ~2440 ft/s, 20" bbl.
And, equivalent "CFE-like" loadings of lever are giving me about 100 ft/s more MV... but ymmv and usual disclaimers apply!
H4895 can do amazing things under a 129 ablr if you have a mag setup and barrel throat that allows loads in the 2.330 length.
Varget is another powder that under a 120 gold dot and a 2.300 coal length or longer will do some amazing speeds from a grendel bolt action.
You couldnt pay me too use cfe223 or leverevolution ever again. They are just too temp sensitive.
Some of these newer listed powders I'm going to have to give a try in my cz grendel and see what they can do at 2.300 are longer load lengths.
