We got rained out of work this morning so I killed some time and a few phonebooks.

Cartridge-.300 WSM
Bullets-150 TTSX, 150 Ballistic Tip and 150 E-Tip
Range-10 feet
Impact velocity-3150fps



Bullets entered from the right and stopped at the arrows.

150 TTSX went 15".
150 BT and ET went about 10-11".

An identical test made last spring resulted in...
180 Accubond 11".
180 Partition 16".
180 TSX 18".
(2950fps impact)

I was quite surprised that the BT and ET stopped at nearly the same page. Figured that the ET would have ended up somewhere between the TTSX and the BT.


Bullet gack...



Width at widest point(L-R).
ET-.685"
BT-.676"
TTSX-.620"



Retained weight.
ET-149 grains/99%.
BT-90 grains/60%.
TTSX-149.5 grains/99%.



The ET clearly has a deeper 'tip cavity' than the TTSX.


Anyway, thought you people might enjoy viewing my big 'hunt'.

I really need to quit killin' books and do a real test this fall.

We caught these two crossing the road on the way out.
I tried to run up to them for a closer look and better pics but Momma was to fast.....grin





Low clouds, nice and cool. Great day for shooting.

Were the books wet or dry when you shot them?



Barnes & Nosler -that would be a good name for a bookstore... bet they'd have a good selection of reloading manuals.

It rolls right off the tongue....grin


The books were a mix of wet/dry. The dark fatty's(in the first pic) were the water logged ones.

Appreciate the test Sam.

I would like to see bullet performance when impact speed is 400 to 600 fps less.

You're welcome bud.

I agree, 3150 is a pretty harsh test.

Good info.

Looks like the E-tip opened up wider, plus has less space between the petals... uh... physics being what they are, and retained weight being the same... isn't that about the ONLY possible reason it penetrated less?

Correct me if I'm wrong... brain no workie today...

My brain never works Jeff but the ET certainly seems to have a 'hollower' tip.

Great data Sam, thanks for posting the results!

No prob dude.

Scrounged up a pic of the ET..



Anyone have a cross sectioned TTSX pic?

TSX win again, the undisputed champ

Yeah but you shoulda seen the hole from the BT....grin

I have, large in diameter and shallow.

Rosie?

kidding

Is this what you were referring to Sam?

You are nasty.



grin

Egad !!! Almost lost my supper. Gag !!!

Sam - thanks for posting.

I agree with seeing what they would do 3-500 ft/sec less. That is if you have more phone books that need killing....... <g>

Those books are too heavy for me to lug out 200 yards away.

Anyone have a .308 I can borrow????grin

Seriously it would have been a good idea to download or shoot them from distance.
