I have a 700 with a 26"Krieger 1-10 twist barrel. I use RCBS dies, I prefer Remington brass if I can find it. The RUM's are tough on primer pockets and the Remington brass seems to hold up better than others. At one time you couldn't find brass but now Norma, Nosler, and I think a few others are starting to make it.
I used to use Winchester LM primers but after having two of them blow and etch my bolt face I went to Federals and have had no more problems. I shoot 180gr.TTSX's and use Retumbo powder, a friend of mine has a very similar rifle and use's the same load data. I am going to try some Reloader 33 as soon as I find some, I've heard good things about it.
