Thread: wanting a 308 barrel

1:10 in 308 will get you up to the heavy heavy pills 200gr +

1:12 to 168's approx

1:13 is used by the target boys that shoot the 155 palma match pills

1:8 is good to stabalize big pills going slow (suppressed loads)

to fast and it will scrub a lot of speed and wont work well with light pills

243, 264 1:8 is good
