just what is 1450fps you are looking for? its a number, it means almost nothing.
do your self a favour, forget trying to get "all" shells at 1450fps. just forget.
make a nice decent shell 1250fps / 1300fps, use high quality components, such as good hard italian lead, good wadding and powders at the right burn rate (with the associated data)
without being too silly. i would never trust anyone to reload for me, especially when you are pretty much chasing the high end of the speed envelope. with (assumed) very little experience of reloading. while i`m pretty confident you can actually make a shell, its not hard. maybe you shouldnt believe everything on the internet. its full of weirdos.
