Been shooting a 270 for many, many, years. Tried them all. (powders) Found nothing better fits my application than 4350. Don't care to use 4831 in my 270. Stuff just kicks to hard for my liking at the speed I prefer for my 270 cartridges. Than again 4831 is my powder of choice for my 243 and 25-06. So you see its not the powders you (think) are best to keep on hand for generic reasons. Choose powders that work the best in each application concerning (your particular) weapon/s. Just a little advice and my humble opinion tonight is all..
