If the tsx were the end all bullet for barnes,they sure as hell wouldn't have introduced MRX with a poly tip. Poly tips sell,they don't deform as easily and they help increase BC. Its the same reason the AB was introduced. Nosler needs to place a poly tip in the partition and be done with it. They tried bonding the partition and it failed. The ballistic tip isn't nearly as frangible as most would have you believe. The original was junk,just like the original barnes x was junk.
