Re: 140 TSX or 150 Scirrocco

I have shot the 160 Accu bond and it has a lower BC than the 150 Scirroco. I have not shot the 140 TSX but Barnes give it a .477 BC (G1). They are usually pretty close. They publish a .529 for the 150 XBT and I get a real .510 or so. (I use a .245 on the G7 so this is close.) There is not a nickels worth of difference at 600 yds with the slight speed advantage the 140 offers over the 150.

From what I have seen with one bull the accu bond is harder (338 ultra). I would have liked some more expansion. The bull was hit to far back on a quartering shot and the bullet only got one lung.(535 yds) An hour later when we found him he could still run. I thought the bullet should have done more damage. We examined the wound channel and it was not as big as I would have expected.

The Nosler has some antimony in the core and a guilding metal jacket where the Swift is pure lead core and pure copper jacket.

If the bullet had been placed further forward I assume no follow up would have been neccesary but with that experience and the lower BC of the Noslers I think the Swift bullets work better for what I want a bullet to do.

The Nosler have always shot well in my limited experience but Nosler always could make a bullet shoot well.

Re: 140 TSX or 150 Scirrocco

How are you testing these, John? Are you correcting for atmospheric conditions? Did you test the 150 Scirocco the same day the 150 XBT measured a .510? If so, you might wonder why the Swift measured so much higher even though it's advertised lower than Barnes advertises the XBT.

In any case, if you test the 140 TSX on the same day as the 150 Scirocco, I'll eat a box of them if they measure a BC 93% as high as the Swift as advertised. It will be much lower. Enough to increase wind drift substancially at long range.

Re: 140 TSX or 150 Scirrocco

Interesting post...I used a 150 grain Scirocco shot from a 7mm Dakota last year on a big Canadian whitetail. Shot was close approx. 70 yards. Bullet totally blew up(pancaked) on both shots. Got the deer but will not use them again. Thinking of another bullet...with the TSX 140 grain in the forefront

I think this discussion belongs in Bullets, Ballistics and Barrels and I will post a reply there if anyone is interested.

thanks
John
