LC brass fired through a quality barrel will produce excellent groups.
Sometimes 5 shots in 1/4". But 1/2 moa is not unusual.
No weight sorting, just buy a lot of one thousand, load and shoot,...get the free primers too.
I use the same busing die on both Lapua and LC.
LC has a little less volume, so drop the charge a bit on max loads.
Even the 50BMG is capable of 1/2 MOA with LC brass and 620 gr APITs for 5 shots. With a bullet that's over 1/2" wide...
