hey trailboss...
If you've read the links Ray posted you probably already know the answers to your questions. If you didn't, here's a few highlights....
Your RCBS dies won't work in the 310 tong tool
If you want to win the 1000 yard match and the rifle you're going to need tools more accurate than the tong tool. A press, you already have the dies, a scale that measures at least 750 grs., a drop tube, preferably a non-sparking powder measure, a means to prime the cases, a means to size and lube the bullets unless you can find them already sized and lubed, and that may well be an option, and if you get into it probably bullet molds and a lead furnace and a few other things that make reloading more convenient but aren't necessary. I, and probably most folks who reload, acquired most of that stuff over time and it wasn't such a big hit all at once. Anyway, I don't believe you can do it on a shoe string and be competetive......but it wouldn't be the first time I was wrong.
Venturino and Garbe put out a little spiral bound booklet called "The SPG BPCR Reloading Primer", or something to that effect. Lots of good info in that little book. Paul Matthews has several books out on BPCR reloading and I've found them informative and useful. I know there are others out there alos, the above are the ones I'm familiar with.
Powder...GOEX Cartridge or Swiss
Primers...Federal 215 Magnum
Bullets.....I like the RCBS 500 BPCR but if you don't cast you'll have to find an outlet for prelubed bullets, then it's a matter of experimenting. Start with something between 480 and 520 grs.
Personal preferences and prejudices often dictate what a person recommends and I'm no different than anyone else. The above has worked for me and worked well. Whatever the reason I haven't won a 1000 yard match and the rifle rests on my shoulders, not my rifle and loads. It isn't them that isn't capable.
