Looks good am interested to see how it performs for you??Well here is my New 6mm br improved case I will test this weekend hopefully.
I fire formed 2 rounds today to check chamber I will start forming about 50 pieces of brass tommorow an test loads for the last 600yd match an report good or bad thanks rushty.Looks good am interested to see how it performs for you??

No worries good luck.I fire formed 2 rounds today to check chamber I will start forming about 50 pieces of brass tommorow an test loads for the last 600yd match an report good or bad thanks rushty.
Yep the one on the left is taller at the shoulder and has a shorter neck. Looks a little like a BRX but with a longer neck.Is it me or do the cases in the picture look different?

Thanks for the clarification. So the case keeps the original 30degree shoulder?
What reamer did you use? Would like to use the same dies and reamer.Tried out my 6BRA dies for the first time. I had a Forster 6 Dasher full length die shortened by 0.082" and the neck honed. Seems to be a very good match for my reamer specs (which closely mirror Alex's reamer print for base/shoulder diameter). I ordered the die from Forster shorter by 0.080" but it wouldn't quite bump the shoulder so had to take the last 0.002" off myself. Forster is advertising making the 6BRA dies as 0.082" shorter so it seems like others may have had the same experience as me.
I'm getting 0.0006" sizing at the base of the case after first firing, .4703 fired down to .4697 sized. Shoulder diameter goes from 0.460 down to .4585". Bumping the shoulder 0.001 to 0.0015 gives effortless bolt close. I had the neck of the die honed to .265 for no turn Lapua brass, current manufacture. I run a Sinclair carbide turning mandrel as my final expanding step to set neck tension. Neck expands about a half a thousandth to hit a final measurement of .2655 with 0.002 neck tension.
Runout is essentially zero, very consistent straight cases even though I'm doing it on a Dillon 550.
Happy with the choice of Forster dies, something to consider if you're looking at the varying die options.
What reamer did you use? Would like to use the same dies and reamer.
Wow looks promising just fireforming.. great range you have there to!Well I formed 28 pieces of brass at 125 yds in my 6mmbr improved 30 degree shoulder
Rushty I just love the challenges of going to our long range matches an sometimes suprizeing the shooters I shoot with great bunch of gentleman they are an the ladies also they don't take no prisoner's we all look for that magic that's what keeps me going I will update as I tune with this puppie.Wow looks promising just fireforming.. great range you have there to!
Im with you there long range shooting is challenging and addictive, having great people to shoot with makes it all that much more fun to boot.Rushty I just love the challenges of going to our long range matches an sometimes suprizeing the shooters I shoot with great bunch of gentleman they are an the ladies also they don't take no prisoner's we all look for that magic that's what keeps me going I will update as I tune with this puppie.
