There's nothing wrong with any of the powders made today. The thing is, some guns like one brand better than another!!! Asking what powder is best for YOUR gun, is like asking what gas will give the best milage in YOUR car.

There are NO bad choises, IMR is good, Hodgdon is also good. I bet you i have loaded several hundred pounds of each of those brands!!!

In a 270 either would be a good choise, as long as you pick the brand of bullet you are going to shoot, and get a loading book for "that brand" of bullet. You will find loads in that manual for the different powders that "they" recomend for "there" bullets, in you caliber.

For rifle hunting bullets, i like Noslers, especially partition bullets. For practice, buy what's available in your area, that is the same weight your going to hunt with, and go for it!!!
