I know the 110g penetrates further in ballistic gel, but how does the slower speed affect penetrating harder substances (i.e., steel or bone)? has anyone been able to burn through steel plates with the 110s the way the 85s have?

 

[airbrusher]

How about for different types of game? Im hearing that the BArrnes 85gr tsx is outstanding for pigs. what about others?

This is what I think after talking to HTR and such about these bullets.... Barnes claims you need around 2200 or so FPS for this bullet to expand the 85 grainers are going way above that so we know it expands when it meets resistance... now the 110 dont get close to the same speeds so your range it will expand diminishes also becuase of that you really need to hit bone for the bullet to expand... I think several people have mentioned that a shot into the boiler room of a deer isnt enough to do it... it may not be enough for the 85's either but last I knew no one had tried it....

I thought the Barnes bullets expanded at 1700 FPS.

I noticed that in your other thread and was going to ask you about that....

I sent Barnes an email asking about them offering the TTSX in a 90 or so grain and they replied:

Found the email from Barnes:

Our tests show that the TTSX opens up at only 1", where the TSX opens fully between 1" and 2". As far as the opening velocity goes, most TSX's require 1800fps, where most TTSX's require 2000fps. The 85gr for the 6.8 SPC has a minimum opening velocity of 2100 fps. This bullet is specifically designed to be a lower penetration round desirable for the 6.8 AR platform for LE and Military type uses. Again I will pass this information on. Thanks

who has the best prices on the 85 gr tsx?

who has the best prices on the 85 gr tsx?

Barnes has them for $30.26 / box of 50...with free shipping for orders over $75.

These velocities sound like they are backwards. The TTSX has a nose cavity twice the size of the cavity of the TSX. The tip obviously acts like a wedge and assists in opening the petals outward as they deflect away from tissue on impact. The TSX does not have this feature, and could actually "implode" into itself at lower velocities, when below the threshold of 2000 or so FPS. However, it is possible that the TSX uses a softer copper alloy. When I shoot them at steel, they mushroom into themselves with the base of the bullet stiking out of the back of the bullet, but they are shaped more like a cupcake than a mushroom :lol: . The 85's, with their speed, managed to sail right through that plate a few times.

I am not sure, but with barnes confirming that the TTSX opens more quickly, it is evident that the tipped bullet with larger hollow point is going to expand more and do so at a slightly lower velocity.

So, what I am seeing in the field, is that the TTSX looks like it is opening up around 1700-1800 and the TSX is opening around 2100.

Thus, I have shied away from the 110 TSX, and moved toward the 85, since I am getting them reliably to the 3000 FPS mark, even out of my 12.5 inch barrel, and more like 3200 from a 20" barrel. I have seen some of the 110 grain TSX's fail to open up, but I have never seen a TTSX open and the fastest I have driven them is 2700.

I think Barnes does need to release a 90 grain TTSX, and just drop the 110 TSX from the 6.8 line. I think the 85 is by far the better TSX bullet. I use the 85's for anything and the TTSX's for deer, but I will only use the 110's for hogs because I cannot get them going fast enough to make them perform like they should.

What loads are you using to get these velocities? I'm looking to get 3 grand out of my 16" barrel with preferably a ball powder. Any suggestions? I don't own a chrono.

110 TTSX -SSA brass, Wolf small rifle military primer and 29.5 grains of Reloader 10X.....gets me to 2696 FPS from my 16" Cardinal superlight 16" which happens to have a .276 bore.

The 85 grain TSX is loaded with SSA brass, Wolf small rifle mil. primer, and 30.5 grains of Re 7. This got me to 2975 FPS out of my 12.5" Cardinal Barrel.

the 85 TSX goes 3200 out of the ARP 12/3.

I load both to 2.30"

I think 3200 from the 85 TSX with a 20" barrel, in 2009 at least, a 'given'. I believe Constructor is close to consistantly getting those same 85 TSX's to 3200 in a 16" barrel, which should easily give 3100 from a 12.5"?

Amazing how far the 6.8 has come in the last year.
