I'm looking to get into 6BR (probably 1-8 twist) and was wondering what some good starting points were for reloading and the approx fps I could expect. Thanks in advance.
 
Done. Now on to primers, is there really that big of a difference? I have CCI 400s and WSR on hand. Should I look at getting the 450s or BR primers? What id the difference?
 
The link I specified above has primer info:

Primer Selection
CCI BR4s and 450s are giving the best velocities, with lowest ES, for the 100+gr bullets. For the shorter bullets, the Fed 205s work well. Federal 205s give good accuracy, but they don't handle high pressures as well as the CCIs, which have a harder cup. Stick to CCIs for hot loads.


I like CCI myself (but I haven't done a lot of comparison between the brands). I'll probably standardize on CCI 450 for all my small rifle reloading (6mmBR, .223).

Hopefully some of the regulars from the Precision section can weigh in on this.
 
From what I got out of the article was that the 450's have a harder cup so they would be considered 'safer' I guess. What I'm wondering from an accuracy point of view is there going to be a noticeable difference using the 400s or the WSR primers, IE are the 450s hotter or something? I use a LEE primer so I won't touch the Federal primers.

Primers are specifically designed to ignite from a hard, sharp blow. They will not ignite from a slow steady crushing or squeezing force. It is possible to completely crush and distort a primer without setting it off.

Many millions of Fed match primers have been safely loaded without being set off.

The idea of a harder primer cup being "safer" only holds true for a semi-auto rifle with a floating firing pin. Otherwise it is totally moot point.
 
There is a section on reloading the 6BR for newbies at accurateshooter.com - most everything you need is covered there. As for the harder (thicker) primers I have read that when loads get to near max they are less likely to give pressure signs a of course less likely to fail. I have a 204 Ruger that has to run the better primers or it shows cratering at medium loads.
 
I am shooting Varget in both my 6br rifles.
RL 15 worked well also, but gave up a slight bit in accuracy.
It is possible to drive a 105 Berger to 3000 in the 6br with a 28" barrel and a 1-8" twist.
I have shot this at 1000 yards with good results.

Varget (30-31.2 range) + CCI 450 + Berger 105 Hunting VLD's jammed .018 into the lands = me giggling like a school girl all the way out to the 1000yd line.
