lI have two Liljas a 10 twist in 270 Win and an 8 twist in 270 AM.
The 270 Win is consistently 'milk jug' accurate to 700 yds. Smallest group, still on the fridge is 3 shots into 0.110 ctc.
The 270 AM is 'yote' accurate to 1400, so far, on rocks
After ~850 rounds and a dose of a treatment, 2 out of 3 shots hit the 'penny' at 200 yds. The third shot didn't miss by much.
Of all of the variables associated with re-barreling I would suggest the Lilja barrel is the least variable. However, there are those exceptions.
