I'm going to have a M700 action rebarreled, probably to the 6mm BR. The M700 is currently a 6mm Rem and should not require any bolt face modifications, right? It's my 1st experience at this and I'm a bit confused.
1. Can anyone recommend a gunsmith to work with a beginner like me?
2. Is 6mm BR Norma the same as 6mm BR Remington
3. Using 68-75g bullets, will a 1=10 twist work?
4. Recommendations for a bench rest type stock and trigger.
5. What brand reloading dies should I get?
6. Am I realistic in hoping that it will group under .5 if I do my part?
I'm not getting the 6mm ppc because I don't want the hassle of making brass, neck turning, etc.
Thanks.

1. Can anyone recommend a gunsmith to work with a beginner like me?
See our list of gunsmiths. They are all good. Some have a heavier backlog than others. Some do stock work, while others prefer to have someone else do inletting, pillar bedding etc. It's always a good idea to find a top smith who lives relatively close to you.
Since you're located in Illinois, we might recommend Kelblys (OH) or Stan Ware (MN) to do the work. Stan is a very fine smith noted for being fastidious about chambering. Not driving distance for you, but shipping costs would be less. He can also true your action at a reasonable cost.
2. Is 6mm BR Norma the same as 6mm BR Remington?
Yes and no. The 6mm BR Norma has a longer neck, and the Lapua-brand brass is very slightly different in the case dimensions, though not enough so that you can't use 6mm BR Rem dies. You want your chamber spec'd for Lapua-brand brass, and set for the long neck. (If you plan only to shoot light bullets you could spec a shorter neck and just trim the cases though.)
3. Using 68-75g bullets, will a 1:10 twist work?
With every bullet we know in that weight range the answer is yes, provided you're launching them at at least 2600 fps. A 1:12 might give you a bit more velocity, but the 1:10 is a good compromise, as you can shoot the 90gr Lapua and 95gr Berger boat-tails.
4. Recommendations for a bench rest type stock and trigger.
Look at our stocks Stocks Page. For a pure BR type stock, we like the Kelbly Klub and the McMillan Edge. But Speedy (SG&Y) and Jim Borden also make good BR stocks. At the high end, John Pierce, Leonard and Scoville produce beautiful custom stocks. Jewell and Shilen both make fine BR triggers.
5. What brand reloading dies should I get?
You won't go wrong with Reddings, but the Forster Ultra Seater die is very good also. For a sizing die, read the article by Jim Carstensen on the home page. You may also prefer Wilson hand dies for seating. They produce a very concentric round.
6. Am I realistic in hoping that it will group under .5 if I do my part?
If you start with a premium barrel (Broughton, Hart, Lilja, Krieger, Spencer etc), and a good smith cuts you a good, concentric chamber, and the scope is mounted right, we would be surprised if the gun was not capable of .3 moa groupings. This assumes the Rem 700 action is trued. Many 6BRs are capable of shooting in the 'teens with tuned handloads and expert trigger-pullers.
One nice thing about the 6BR, something we hear over and over, is that the caliber is very easy to tune. "Shoots good with every load I try" is a typical report. As we said in the Reloading Info page, 30gr of Varget, an 80gr Fowler bullet and CCI primers should get you way under .5moa with a well-built gun. But the chambering is critical, so that's why you want to have a very good smith do the job, using a reamer optimized for your bullet choice.
