great groups those kriger barrels really shoot well what reamer did you use for the chamber ????
I don't recall exactly, I'll ask my smith. I know that right after break in the OAL to the lands of the 140 Berger VLD was 2.870", and also that it is throated for VLD type bullets. I got my 140 VLD'S up to 3020 fps, but groups opened up to .75 MOA, which I consider unacceptable in my rifle. .5" groups @100 yards is pushing the limits for what I will accept during load developement. With my current VLD load, it will print in the .3" 3 or 5 shot groups or less every single time. My 10 shot groups with them fall under .5" every time if I do my job.
May I suggest trying the CCI BR-2 primers with your load...it cut a couple tenths off my groups and brought my E.S. from 20ish fps down to single digits, and I didn't change my powder charge.
