As I said above: "... I would really like to see Weatherby replace the 225gr TSX with a 225gr TTSX if possible ..."
WEATHERBY PEOPLE PLEASE LISTEN:
I was intrigued a couple of months ago when I saw that Cor-Bon was coming out with a new 225gr TSX loading in 340 Wby with a little more umpf than the Wby loading (3100 fps vs. 2970 fps). But it still did'nt not solve the ballistic inefficiency of the 225gr TSX round with it's low (0.386) ballistic coeficient (because it's a non-boattail). Thus, the TSX was great coming out of the muzzle of a 340, but by the time it sailed about 300 yds, it was about the same as a Nosler Partition coming out of a .338 Win. Mag. Who wants a 340 Wby that hits down range like a .338 Win Mag? Not me.
So, minutes ago, looking at the Midway and Cor-Bon website, I just learned that the new CB 225gr Barnes loading is a TTSX, not a TSX. That bullet has a great BC of 0.514. With the starting velocity/energy of 3,100 fps/4,801 ft-lbs it still delivers 3,244 ft-lbs at 300 yds and 2,467 ft-lbs at 500 yds!
Using my ballistic calculator, at long ranges, it delivers more energy, drifts less in the wind, and drops less than any round loaded by Wby (in Wby's own cartridge). And it does it with a better bullet than the Nosler Partition or Accubond. At least in that the monometal T-TSX will consistently perform better on tough game at variable ranges. In any event, it out performs all of Weatherby's loadings at all ranges in so many important characteristics. If I were a handloader, and had the time, I would load something exactly like that--a 3,100 fps 225gr TTSX.
I already sighted in my Accumark with the Wby factory 250gr NPs and was about to order more, but I just ordered five boxes of the Cor-Bon ammo and will re-sight-in for my fall Alaskan bear hunt. It's exactly what a high-end round like the 340 Wby should do--deliver 30-06 muzzle energy but at 400 yds and with a subperb premium bullet.
I would gladly order something this awesome from Weatherby if they loaded it. But, for now, I'm limited to Cor-Bon for this kind of performance. Please Weatherby, load up with some high-velocity premium bullet made for really tough game--maybe a 250gr MRX or something. Compete for my business!
