I'm gonna start reloading .270 win soon but I was trying to decide on a powder to use. I have looked in my reloading manual and am leaning towards IMR powder (I forget the number) but I remember from somewhere that some powders are dependent on how they sit in the case and others have been formulated to give consistent pressure regardless of their position. Does anyone have any suggestions?

IMR 4831 (SC) is the quintessential 270 Win powder, the few that don't use that often opt for the highly versitle IMR 4350 or W760, though I think RL19 would work very well too, what weight will you be loading?

IMR 4350 is a good all purpose powder and one of my favorites. works well in many different calibers and cartridges. i probably use more of it than any other powder i buy. IMR 4831 is also a good choice as is IMR 4895.

H-4831 SC is a great powder for large case capacity rifles. SC stands for Short Cut. The individual kernals are smaller. They meter better and you can theoretically fit a bit more power in the case with the SC.

Do you load anything else? I prefer to find powders that work well in several different calibers. I keep two pistol powders, three rifle powders and three shotshell powders, that's it.

IMR 4350 is what I was leaning towards because it was a good performer in my hornady reloading book.

However, my dad shoots .243 win and I short of wanted a powder that I could use in both loads.

I've been loading .243 for a little bit and after looking in my manual, Hodgon 4350 and Accurate 4350 come up under that and the .270 as well.

H4831SC is listed as the most accurate powder for 130gr 270 Win and it is the second fastest right behind 760. 4831 is also a top choice for 243 in 85-90gr bullet weights, and I know a few people who like it in 100gr too. But if you are looking for one powder to rule them all 4350 is it, med-slow burn rate works in everything, all five of my rifles have good shooting 4350 loads everything from 308 to 270 WSM.

i have many different rifle calibers i reload for and like powders that will work in several instead of just one or two. when making powder choices this what i look for. a broad range or even potential calibers in the future.

Oh forgot to mention, if you are going to be shooting heavyweight 150s or 160s get some RL22, anytime I need to push a heavy for caliber bullet to impressive speeds with pinpoint accuracy that is my go to stuff in everything but the 308 and 7mm-08, they simply don't have the case volume to use anything that slow burning.
