   just got a 270 wsm rifle from a member on this site.  with it came brass and 130 grain nosler bullets with a white deal on the tip.  am looking for a good recipe.  what is a good powder?  what primer should I use?   mike w

I would recommend picking up a couple reloading manuals to get a good baseline.

H4350 shoots well in my WSM's.  It also shoots well in my 7x57's.

  am going to use 4350.  now how much powder do I use?  I have 2 reload manuals but they were printed in the 70's and the 270 wsm was invented the turn of the century.  will get one next time I am in a big town.  will big rifle primers work?   where on the internet can I find info on the 270 wsm?   thanks,  mike w

Don't reload anything til you have a current Nosler reloading manual. Internet load data shouldn't be trusted without experience.

You can trust the data from the powder and bullet manufacturers.  Other sources take with a grain of salt...

New Nosler manual shows a load for 130 gr. And most accurate powder
Is IMR 4350 says most accurate load tested is 59gr. The Max load with it is 63gr.

I like the Nosler manual as well.  Plus, since you have the Accubond that might be of a little more help. 

I've seen published loads that call for Large Rifle primers and some that call for Magnum primers.  Both will work ok, but I found the Large to be inconsistent when we hit colder weather.  So now I only use Magnum primers in my WSMs.

I also found the RL17 and Norma URP powders a bit inconsistent in my 270 WSM.  Speeds were good, but my gun refused to group anything I tried with either.  RL19 and Norma 204 were what my Sako liked best with the 130 grain Accubond.  N204 being my load now.  I was surprised at how such a small step slower in powder burn made my processing window so much wider.

The other thing that surprised me with the 270WSM was that I got my best groups when I full length size the brass.  Not sure if other WSM shooters have found the same thing.  But at least for me and/or the Sako it was noticeable.

Also, the 270WSM is the only round I shoot where I get my best groups with Barnes bullets.  The little 110 grain TTSX has proven to be quite impressive!  It likes the N204 powder too.  Have used IMR4350 with the 110 TTSX with good results also.

Some good observations there. Things went better for me and my handloads with the .270 WSM when I switched from Winchester large rifle primers to Federal Magnum 215's. I'm not a big fan of the .270 Winchester but the the .270 is a huge step above velocity wise. It nips on the heals of 7mm Magnum performance and that's a great thing on a 24" short action. The chambering has been quite accurate and taken everything I have shot with it quick and clean out to just short of 400 yards and I just slum a factory Rem700 SPS synthetic.
