I already reload 9mm and .45 as that is the calibers I have always owned. Recently came across a great deal on a G22, so I am going to need to start reloading .40 as retail ammo makes shooting less fun (free ammo is the funnest). I use Accurate No5 for 9mm and .45. I was planning to use the same powder for .40. This will primarily be a range and IDPA gun. I would like to use the same powder for all my handguns to keep things simple but would use something else if it is far superior.
