Not sure about the 6.8s, I thought the TAC line was softer but others say identical to TSX & TTSX. Might contact Barnes. The LRX has a deeper hollow point and I suspect they anneal the bullets too.

One Australian writer (and maybe others) anneals his factory bullets but I don't know how well you could control the results? One factor is if you over do it you melt the tip.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
