hey,I can not say anything about a 270swm,but take it slow.any case is something to start on.read and read some more.get some data.I like nosler bullets so I have their books.reloading can get expensive with all of the info and tools.so get the basic tools and give it a try.just keep your loads safe the powder people and bullet people have done most of the work for us.we just have to adjust sometimes.I wolud think that a 130g bullet would be a great choice to start with.they shot good out of my 270 win when I had one.and never be affaid of asking a question no matter what it is.thats how we learn.ye it my have been asked before but it can also be answered again.so don't give up.go to the reloading forum.try differant sites.John
