WOW!! I cant believe the Nosler actually got that many votes! Dont get me wrong, its a.superb bullet, but isnt in the same league as the TSX.
I handload for a lot of people, and I do a lot of bullet testing. Usually, I take those square boxes you get for free at the grocery store (the ones that 4 gal.s of milk come in) and I pack them as tight as I can with old phone books, Sears catalogs, magazines, staxks of newspaper, etc. sometimes I even insert bones in there, from deer or chickens, and soak it in water for a couple hours. Pistols only require one box, but rifles need 2 - 4, depending on caliber. shooting this at 50 yds or less is a testimant to a bullet's strength, as all but the best will fragment or separate.
I used to use the Partition to deer hunt with my AR15, the 60 grainers are great... then I started testing the Barnes TSX and Tipped TSX. I have yet to see one break apart or fragment on something living. I even shot a hot load at one of my test boxes with a 20" AR from only 10 yds with a 62 gr. TSX, with a muzzle velocity of 3205 fps - and it didnt break! The petals were flattened against the body, ans retained weight was only 56 gr, but it held. I did the same thing with the 60 gr partition, and the upper half of the bullet disentegrated, and all I could find was the lower half, base of the bullet, below the "partition", badly deformed. Weight was 41 gr - nearly lost half its weight.
Also, in my rifles, the Barnes are more accurate, especially at longer ranges.. howevet the Nosler is no slouch in that department either. Nosler should ditch the lead tipped spitzer design and make a polymer tipped boat tail partition. I have tested thr TSX and T-TSX in .224" 62gr (cant find the 70's anywhere).. The 165 TSX and 168 T-TSX, in .308" from a .308, and the 168 and 180 in .300. I have some in .260 Rem and 7mm Rem Mag, but havent tested them yet.
Using my test, Nosler Ballistic Tips usually fragment if less than 100 yds, the Swift Scirocco's penetrate too much before expanding, or ice pick all together in .277". Hornady SSTs are my favorite "cheap" hunting bullet.
I'll try to upload some testing pictures later ... its interesting stuff
