Home Forums Hunting & Shooting General Big Game Barnes vs Partitions vs Ballistic Tips

MD


I first posted in this thread because i didnt feel it was a fair comparison in wound channel size when comparing 168 mono vs a 168 cup and core. we all know monos expand more reliably/violently when the speed is higher and/or bone is impacted.
I'm not stating that Barnes bullets make the biggest would channel or kill as "quick" as a VLD.
But I'm not buying that a 168 tsx at 2600 makes the same would channel as a 130 @ 3100...
Or a 110 at 3350

Am I wrong?

Based on the Info below... Same bullet with different impact speed changes size of wound channel and penetration.


"The most important bullet characteristics with regard to terminal performance are expansion, weight retention, penetration and wounding qualities. Without knowing these, you are pretty much shooting in the dark as to bullet suitability for a particular game species and downrange performance. To test these traits across a spectrum of muzzle and impact velocities, I shot sample 130-grain TTSX bullets through a .300 Whisper, a .308 Winchester and a .300 Weatherby Magnum into Bullet Test Tubes with Extenders at 25 yards.

With a muzzle velocity of 2,013 fps, through the .300 Whisper the TTSX expanded to .541 inch, retained 129.2 grains of its weight, penetrated 14 3/4 inches and produced a .667-inch-wide wound channel. At a similar velocity, the TSX expanded to .439 inch, weighed 130 grains, penetrated 13 1/2 inches but veered severely off course at the 6-inch mark while creating a .638-inch-wide wound channel.

Propelled through the .308 Winchester at 2,878 fps, the new bullet enlarged to .614 inch, kept 129.3 grains of its weight, pierced 15 inches into the media and formed a 2-inch-wide wound channel. The most punishing evaluation came when I launched the TTSX from the .300 Weatherby Magnum at 3,562 fps. It penetrated all 20 inches of Test Tube and Extender and exited, but not before leaving a 2.371-inch-wide wound channel and shedding a single, 11.8-grain petal at the 11 1/2-inch mark. It�s possible to argue the recovered bullet weight would be between 117.3 and 117.6 grains. "


so here is the results
130 TTSX
speed---- expansion --- penetration-- would channel
2013 --- .541" --- 14.75" -- .667"
2878 --- .614" --- 15" -- 2.00"
3562 --- n/a --- 20"+ -- 2.371"



also MD, your story involves the TSX like this post does.... I submit the ttsx is a different animal as indiacted by the hollow point difference below


130 TTSX with polymer tip pulled out.

On the right is a 168gr TSX. I would rather shoot the 130 TTSX at deer based on this picture
