QUOTE Jordan Smith from other thread
The TSX, just like almost every other expanding bullet out there, is fully expanded within an inch or two of entering the animal. It's not a question of how quickly it expands, but how easily. And my experience (shot and seen shot around 80 big-game animals with X/TSX/TTSX bullets) is that TSX bullets expand extremely reliably.
I believe that guys often think that the bullet has pencilled through, when in reality the bullet hit the animal, expanded immediately, did a bunch of damage to the internals, lost its petals, and exited the offside as a wadcutter. People see the small exit hole in the hide and assume it didn't expand. They often don't judge expansion characteristics on the damage done to the insides, but based on the exit hole alone, which is flawed logic, in my book.
You definitely don't need Barnes bullets for most deer shooting. They come in handy when taking a hard quartering shot, or an end-to-end shot. Of course it doesn't hurt to use a TSX/TTSX when shooting through heavy bone, either. Where they really shine is when hunting larger game than deer, and I'm often hunting elk, WT deer, black bear, etc, all at the same time. The TSX/TTSX works great as an all-purpose bullet when I never know what I might see. QUOTE
I would like to add that Federal 25-06 Barnes 100 TSX factory load has MV of 3210 ft/sec.
and as per manufacturer design Barnes should open as low as 1600 ft/sec which gives 825 yards !!!
And 257 Weatherby mag lists 100 gr bullet at 3520 2147 ft/sec and 1023ft/lb at600.
Don't have 257 AI with me right now
I would not use lead containing bullet for hunting. So my advise to OP is keep shooting 100 TSX for everything.
Watch this one
