a 255 grn rnfp boolit seats no deeper in the case than does a 230 hp jacketed.
i commonly shoot a 275 grn by hunters supply with zero feeding or pressure issues just under 900 fps also using 2400.
but now this is a totally stock glock which as we all know is simply the greatest 45 ever made..
that is until we start trying to improve it with "fully supported barrels" and heavier springs..
really though there truly is a lot of stuff out there we get sold on the idea of that makes far better press than sense.
you are reinventing the wheel my friend, as you will discover in time if you research it long enough.
