My 300 blk HD gun has a magazine of Lehigh Controlled Chaos in the gun, and a magazine of the Barnes blacktips sitting next to it.

Lee 230gr 300BO mold, makes a 225gr cast boolit, powered by 10gr Reloader 7.
Quiet and hits like a 45ACP
this is the load if you have the time to cast and handload . I powder coat mine

OP,
    The 110GR. TAC-TX based Barnes® VOR-TX™ 300BLK cartridge is hard to improve on as a General Purpose 300BLK load especially for a hunting application. But it does have a couple of possible drawbacks for LE/SD/HD use: over-penetration & non-fragmentation.  These (2) characteristics are linked in that a bullet that does not fragment tends to penetrate deeper. The Barnes TAC-TX bullet does not normally fragment at all so it penetrates very deeply, almost too deeply for SD/HD/LE application. Over-penetration is a very real possibility, almost a certainty IMO. And controlled fragmentation is not necessarily a drawback as it has value as a tissue damage mechanism especially if the bullet also yields sufficient penetration. An accurate bullet designed for 300BLK application that balances expansion with controlled fragmentation over a wide range of impact velocity would be well received IMO. The BARNES TAC-TX and the LEHIGH CC Cu were designed from the ground up to expand/fragment at the very low impact velocity seen with the 300BLK out at 300yds. even from a 9" barrel yielding impact velocity of 1350-1400 FPS. With all that said, the 300BLK load I would currently trust to immediately stop a home invader with a single shot to the kill zone is the BHA 125GR. TMK. But even this TMK load has its drawbacks as a GP 300BLK load.  The 125GR. TMK bullet does not expand/fragment at impact velocity below approx. 1800-1900 FPS. This limits its useful range to approx. 100-150yds. for hunting application but is plenty for most LE/SD/HD applications. Currently, we have some very solid choices. And we are getting closer to the "perfect" General Purpose 300BLK load/bullet all the time. .02

Eagle,
    Sierra has been anything but helpful when it comes to supplying useful information on using the SMK or the TMK bullets on flesh & bone targets. One email reply from Sierra finally stated that they don't even test their SMK or TMK bullets for expansion/fragmentation properties. If that is actually the case, then Sierra has no real idea what level of terminal performance their SMK or TMK bullets are capable of. Whenever I need usable information on SMK or TMK terminal performance, I look to BHA for information on their  loads. BHA manufactures actual SMK & TMK based ammunition & they have always been thoroughly familiar with the gel-shot performance of their loads. I don't believe BHA would waste valuable time gel-shot testing then manufacturing loads that don't have real-world application on flesh & bone targets. Jeff Hoffman, co-owner & President of BHA, is also a long-time LEO/sharpshooter/sniper, first commissioned in 1979. As such, I would think it a safe bet that he looks at terminal performance from a LEO's perspective: fight stopping terminal performance up close with sufficient accuracy for use at longer range. Referencing the BHA 125GR. TMK gel shot test above: That level of tissue damage inside the chest cavity of a home invader will very quickly end the fight IMO. And the dozens of game-shots I have taken  with the 125GR. TMK at what would be considered normal SD/HD range mirror BHA's gel-shot results. Bottom line: Do I think it a mistake to opt for the Barnes 110Gr. TAC-TX black tip bullet based VOR-TX™  load as a General Purpose 300BLK load? Absolutely not. .02
