There are as many (or more) people cursing Barnes as there are those praising them.
Their previous offerings WERE very sensitive to overall length/bullet distance to the lands. As such I never tried them...............UNTIL I saw the, then new, TSXs at the NRA Convention and talked to their Reps. I had to try them in my .308s when they hit the shelves and have been very pleased with them. They aren't really sensitive to length as I fire them in my M1A at a standard 2.80" length and get GOOD accuracy with the right load. AND almost no copper fouling at all - another big problem on the older, non-coated Barnes bullets. Performance on game is outstanding, just as advertized, even on heavy critters like wild boar.

They ain't cheap, but they are worth a try.
