Looking at various load manuals, book form and on-line there are many powders recommended for .243 win, but which is the right one ?
The more I look the more undecided I am, I want to use 75 grain bullets, maybe V-max, maybe hollow points for fox with the outside chance at small deer.
The powder needs to be available locally and temp stable, I don't want to load different powders for summer and winter, or have a big variance in fps dependant on temp.
Looking the the Hodgdon site, H414 fills these needs, and does it at lower pressure and gives a high fill %, is this a good enough reason to go with it ?
Or are the differences so small that any of the maybe more common choices are equally good, i.e. Varget or H380, or IMR 4320 or IMR 4895.
I note also that these powders occupy very different places on the burn rate charts, but seem close in claimed velocity and pressure, what difference does the burn rate make, or is it a case of choosing slow or fast dependant on barrel length ?
