Nosler lists the ballistic coefficient as .276 for the 55 grain bullet. As to the distance for best grouping...most people test their loads at 100 yards (or meters, depending on units of measure that you are used to) and then plan to roughly figure groups as the distance increases. If your groups are 1 inch at 100 yards (1 minute of angle or MOA) they should logically be 2 inches at 200 yards, 3 inches at 300 yards and so-forth. That is only a guide, however, and you need to shoot at those distances to determine what your rifle/load combination can actually do.
The same goes for using ballistic software. Point Blank is reliable and amazingly accurate (assuming you input valid, accurate information), but only real-life shooting will guarantee the trajectory picture for your particular load.

The biggest problem with a closed mind is that it never seems to come with a closed mouth.

Strangely enough, I've been discussing AR2208 elsewhere in the past couple of days.
I doesn't appear to be available outside of Australia & NZ.
I've been told AR2206 is marketed internationally as Hodgdon Varget but no word on 2208.
Edit: Just found the Thales site & AR2206 is equivalent to BLC-2
2208 is Varget.

Menace, somewhere on this site there is a thread about reloading benches with pics of various ones.

Menace, there are some threads here about starting reloading too. And I know that we have some very knowledgable folks around who will be happy to help by answering any questions. By the way, almost all of my reloading equipment is Hornady or RCBS.

Menace, my reloading bench is made from 2x4s with plywood bracing. It's 2' deep and 4' wide. 0.75" plywood top with 2x6 boards running front to back under the presses.
As for the VTR, I haven't really shot it much. So far factory and handloads developed for other guns are running 0.8 to 1.5" groups at 100 yds but I'm sure it could do much better. My buddy also bought one and he shot some 0.5" groups using Hornady factory loads with 40 gr V-Max bullets.

You now have a similar setup to what I started with mate, only I bought the Simplex 'O' Frame Master press and Simplex Dies. They aren't RCBS, but they are still good quality.
The Redding scales and Powder Throw are pretty good, but DON'T leave powder in the powder throw hopper...it will attack the plastic (been there, done that ).
I found that to get a consistent throw of powder I swing the charge arm to the top and "tap" it briskly against the stop, ease it off a cm and "tap" it up briskly again....shakes any powder out that may have hung up in the chute. I also keep a piece of garden hose about 15cm long beside the powder throw...no its not to threaten it wiv...I use it to beat it up...I firmly 'tap' the metal part of the hopper 4 or 5 times every 10 loads to settle the powder. Also, keep the hopper at least 2/3 full...again, throws more consistently.
I loaded thousands of pistol target loads on this setup and had no complaints once I worked out the idiosyncrasies. I still use it today and that is after 30 years of use.
Cheers, Vince

Vince brings up a good point. I use a screwdriver or small wrench to tap the powder measure a few times when I first pour the powder in to make it settle. Then, as I throw a charge, I bump the handle against the top and bottom stops pretty briskly to both settle the powder and jolt the charge loose. I think the key here is, as usual with hand loading, consistency. Always bump it the same way, whether it be once, twice, every fifth load, whatever.
Menace, if you like I’ll send you some info and pics on how I put my bench together. Of course you might have to wait a bit for me to clean it off enough to get some details…

I loaded up some .243 with Varget over the weekend & if the weather forecast is wrong, might get to try it on Sunday:
55gr Blitzking
Loads from 41-44gr.
90gr Gameking
Loads from 33-35gr.
I've seen reports that the Blitzking wont take velocities over 3,500fps, so we'll find out if that's true.
