I played with some ballistic calc numbers, and noticed that left-hand vs right-hand twist difference becomes larger and larger as barrel twist rate becomes faster. For old slower twist barrels, the difference between L vs R is small enough to be negligible. But for 1:7 twist barrels shooting 6 Creedmoor, L twist was 16" closer to the target at 1000 yards compared to R twist!

So I am thinking of trying a left twist for my next long-range build. Who are the manufacturers that offer left twist barrels (besides Bartlein)?

Thanks!
