I have been looking for a single powder that I can reload .223rem,.243win, 6mm rem and 270win and the one that seems to be most suitable for all the above and various bullet weights for them is the IMR and hodgdon 4895.
What I really want to know is
1: how good is this powder with the various calibre/bullet combinations.
2: Availability. Lancs/west yorks area.
3:The difference between the IMR and Hodgdon powders.
