Paraphrasing Jan Libourel, "The gun industry thrives on novelty. Would I trade my 270 Win for a 270 WSM? No. But were I in the market for a new rifle and didn't have a 270 Win, the 270 WSM would have greater appeal"
Gun markets are tight and getting more so each year. There are fewer and fewer of us each year, less and less land to hunt and fewer places to shoot. The next generation of shooters is not nearly as likely to own several of one type of gun as they are to own a few better and best quality guns. That is I think the market TC is really going after.
Sad though, I too wish they had instead offered a switch barrel bolt, or even a switch barrel falling block design. I hope the bolt does well for them, but I think it would be better to leave that market to Savage and develop arms to fill other markets, it seems to be what TC does and does well.
Would I have a 30 TC? Not when a 223, 243, 25-06 and 30-30 fill all my shooting needs. I don't need another rifle, I need another Encore frame to support the barrels I have. In the end, I think the 30 TC will flop for the same reasons the WSM and WSSM's will, there was no demand for such cartridges, and any niche the 30 TC fills is more imagined than real. Nothing shot with it, paper or elk will be any deader than if shot by a 308 or 30-06, and any other advertising hype is just that, hype and once it's in the hands of shooters, the real truth will be known and it will become just one more of a plethora of 30's that are available but seldom seen.
