I am loading 270wsm rounds and am loading Barnes TSX 140gr, Nosler 140gr CT, Hornady 150gr SST, and Barnes 150gr MRX. Is there a common powder I can use for all of these rounds.
 
H4831. Norma 205 and its replacement, NMP, were better, but only found, sometimes, at gunshows.

Don't you have any reloading manuals?

I don't load for this round, but looking through my 6 different manuals there are a lot of choices for you to pick from. there is data for all of these with Reloader 19 and most of them with Reloader 22. H1000, IMR 4350 FS
 
No I don't, I am new to reloading and it seemed unusual that I would have to use a different powder for each individual type of bullet. I have been doing so research and from what I can see so far MagPro appears to be a pretty good powder for all of the loads I am planning to load. I am just looking for help from others in the reloading group with a lot more experience than me so I do not blow my head off.

BUY RELOADING MANUALS!!!! .....or go to IMR's website and get your load data downloaded and PRINTED so it's right beside you at the bench.

Dont rely on anything someone on the net tells you as fact.
Even good intentions are subject to typing errors.

Best of luck and take care.:)

When I replied to your request, I missed the "SM" designation, and looked on it as a 270 Winchester. I have had a fair bit of experience reloading a 270 W, since I bought my first one in 1965. By the time I had shot a thousand rounds through it I bought a box of factory loads, to get brass. I realized that was the first factory loads to be fired in that rifle!
You are loading two different weight bullets, 140 grain and 150 grain. In the 270 W. H4831 is ideal for those two bullet weights, and I think it would also be ideal in the 270 WSM.
In any loading chart for your rifle, select the starting load for 140 grain bullets and, I would suggest, H4831 powder. Never mind who made the bullets.
If you are completely unfamiliar with reloading and judging pressures, maybe you should stay at the starting load for a while.
Later, you can work your load up, after you know how to judge pressures.
Do the same with the 150 grain bullets.
In any case, you do not need more than one powder for the two bullet weights.
There MAY BE a slight change of pressure between two different brands of bullets of the same weight, but starting at the starting load for that bullet weight, will certainly take care of any difference.

Edited to say I am unfamiliar with the powder you mention, but if a book says it's a good powder, use it.
 
Barnes bullets require Barnes data. They're solid copper and don't fly the same as a lead core bullet. There's data on their site under 'Technical'.
The other two can be loaded using data for the bullet weight out of any manual. There is some Nosler data on their site too. Hornady doesn't put load data on-line.

What manuals did you find, the new Nosler manual is great I think. I like the Sierra manual, then the Hornady in my order of preference. FS
 
umm.. well i have a lot of manuals but i rather get my loads off the hogdon website myself. lol.. but i guess reload manuals are good for teaching new reloader's the do's and dont's
