A super LR cartridge. however, you need a very tight BR setup to run at the elevated pressures many use to make this case size work.
Some are achieving 2900 to 3000fps with the 105/107gr bullets. That is very toasty but manageable in a BR action (zero tolerance). For a simple rebarrel job, your performance will fall short. Reload manuals place the max velocity in the 2500 to 2600fps range.
However, it still pushes 87 to 90gr match bullets at wonderful velocities that are fun out to 1000yds. I used to plink clays at 750 to 800yrds without much issue IF I could dope the wind.
If you intend to compete, then consider a larger case. The new bullets of 115gr and heavier are simply too heavy for the BR case. There are many versions built on the 22/250 case and Lapua will be bringing in a 6.5X47 which will be ideal when necked down to 6mm.
Just remember that the very short OAL of the 6BR will make it very hard to feed from a mag without serious work. This is usually a single feed rd.
I really enjoyed mine but have since gone to larger cals and cases to get more performance at 1000yds and beyond.
As a competition 6mm 1000yd/m rd (it will still dominate 600yds match shooting), its days are numbered. As a wonderful LR wildcat for everything else, simply a lot of fun.
