Quoted: The Swift, hands down, is the best bullet. High BC with great weight retention. The sectional density is also good for the closer range work. It still has acceptable penetration at higher velocity, close range work. The Barnes might not expand at the longer ranges as it has a lower BC.

The Swift SD (.214) is certainly right up there (77gr SMK @ .219), another lethality enhancement over the more established .224 hunting bullets. The Swift SD is only 7 percent better than the TSX @ .199. Wasn't sure how that'd translate comparitively or if a meaningful degree. However, it seems to me that the 14 percent SD over the
Sierra 65gr Gameking was substantial enough to be a notable lethality improvement in deer.
If you load it correctly, it will be good out past 300 yards with enough velocity to assure expansion. Sure, you might think you can dial in drop or hold over but only if you are absolutely sure of the range and more importantly, wind.

I would like to see spec data for the expansion-to-velocity comparison for the TSX/Swift in .223. I've seen some captioned pics of the Scirocco, but it didn't specify what caliber bullet it was and I wasn't sure if the same extrapolation would apply to diffrent size bullets. The higher BC was more relevant to me in that the subjective bullet would be maintaining more energy at distance than a lower BC one, not so much the wind/elev dope - albeit, that's not an insignificant element. I can deal with bullet dope, but I can't control what steam it has when it gets there though, I guess. That's up to the bullet.
The old adage of 1000 ft*lbs is pure hooey. A gut shot with a .375 H&H Mag FMJ is no more lethal than the same shot with a .223 Rem softpoint.

Lots to be said for that. It's a long story and isn't what it appears on the surface, but I had a big buck go down (permanently) to 00 buck at 150 yards. I do think that tertiary tissue damage (concussion to the tissue) has an important threshold and is accomplished by the available energy. But like so many other things, it isn't the "all important" factor. It's like saying the carburator is "the most important" element of a NASCAR motor.
.223 Remington is only the name, all .22 center fires in common use today are .224". The .22 Savage High Power (.227") is obsolete as is the .22 Jet (.222").
Now imagine the 75 grain Swift in a fast-twist .224 Middlestead at 3500 FPS! It is still going at 2800 FPS AT 300 YARDS!

Hooo-doggy! That's a .223 kick-in-the-pants! Never heard of it before. Just looked it up. I can only imagine what the life-expectancy of
that critters throat is! Reminds me of a woman I know that smokes 3 packs a day - as soon as she talks, seems like she aint got no throat
I can see myself driving something like that someday.
Good stuff.
Edit for Sierra, not Swift... the hand was quicker than the mind
