I have always used IMR 4831 to load for my 270 Winchester with 130 grain Hornady bullets. I cannot find this powder anywhere.
I can get IMR 4350 but not sure if there will be an accuracy compromise.
Thoughts??
 
I faithfully use IMR 4831 in my 270 Win as well. Staball 6.5 is just about as good as the old IMR standby in my rifle, velocity and accuracy are great as well. Staball will also save you a few dollars over 4350, but both will serve you equally.
 
I used H4831 for a while then switched to Winchester's now long gone WMR. It gives basiclly the same velouty and better accuracy in my .270 Rifle. It's also a winner in my .280 Rem. and .300 Win. Mag. I have no idea why it's a disaster in the 30-06 but even Winchester's load data showed it as not working.

I always used H4831sc in my 130 and 140gr 270 loads. I am sure H4350 will work well. I would also look at n555 and n160 and Ramshot Hunter
