130gr TTSX

Here is the target

You can see the first round (64gr) at the bottom of the target
 
They are seated to fit the magazine, they are not "kissing" the lands or anything. Round count is about 500.

I've found that the TSX bullets don't need to get smoosed into the lands, although some people do it that way with great results.

This is a 7mm RM, Ruger 77 MK II with over 2000 rounds fired through it. The bullets dont' come anywhere near the rifling.

140gr TSX, 3 different powder charges

Why 130's?

Wouldn't a 180 or 200 be a better all around choice in you magnum?
 
I have a bunch of those in 7mm - 140 grain that I will try in my 7-08AI. New to me rifle, but will try 140 Partitions, 140 Accubonds and the TTSX's. Whichever shoots consistently the best will get the nod, of course. Will report later. Regards, Eagleye.

For a TSX style bullet, I think a 165gr would do fine for an all around bullet...

But I'm not convinced a 130gr wouldn't do just as well. I use a 140gr TSX in my 7RM as an all around bullet, so it's not too odd....

A recent Dave Scovill article had a 130gr TTSX in Africa (from a 300 WM) and apparently it killed and destroyed vitals liek nothing the skinners had ever seen.

He shot a kudu (which are similar in size to elk) from front on, and the bullet penetrated tothe rear.

I am sure that they will kill a bear or sheep....:)

The 7mm 140gr has the same sectional density as a 165gr .308.
The 130grain TSX has the same sectional density (.196) as an 80 grain .243?!
Personally its not something I would select for a moose,elk, or bear bullet.

I read Scoville's story and I've seen the devastation first hand, but I'm not sure about using a bullet so short.....

Magazines say a lot of things.....I'd consider setting up a long shot at a black bear to see how well it actually performs.
 
The 130gr TTSX is longer than a 150gr Hornady interlock.

Not that it matters much, since SD changes as soon as it hits the animal.

No way to know what it can do until someone tries it out!:)

I intend to shoot the first 5 ft + black bear I see. Through the shoulders or head on, and I'll check what happens.A 5 ft black bear is not a moose, but it's the only thing open right now.;)
 
Clarke, as always, I'm looking forward to reading about your results. I'm going to lay money right now that any bear you encounter is in SERIOUS trouble with that load.

Depending on your results, I'm going to try the new 123-grain TSX (.310) in my .303. It might add a whole new dimension to that ancient cartridge.

My last order for bullets and brass was over six months ago.... So they obviously clamped down on this shipping policy, had no problem before that.... Will that sucks, they were very good to deal with...

Well I spoke to soon about them having in stock what is listed in their catalog as they had to put the .375 die set on back order and the same with a 9.3 Lyman "M" die......but they filled the rest of the order..and the fellow taking the order said no they don't ship the controlled items listed on the shipping page to Canada...:(

Black bear are a very soft target and easily killed, one wouldn't be much of test for the bullet.
With the legion of critters that have died from a 130 grain bullets out of a 270 I can't see why the 130 grain 30 cal won't be a great bullet.

Pretty much what I was thinking. Yes, the SD is different. But a 130gr Partition in a .270 is a real killer, so why not a 130gr TTSX?
 
Becasue X bullets in general have the same depth of hollow point within caliber, and becase the high velocity of a light bullet load equals the momentum of a heavy but slower bullet bullet; I would expect the 130 gr TTSX to perform similarly to heavier TSX bullets of the same caliber.

Which is also something to consider...

I only made 4 rounds, so the bear gets the first one, then maybe I'll shoot some paper with the 130 and 180 TSX, see what happens.:dancingbanana:
 
Nice to see the good performance Gatehouse. Although, not really surprising after the experience I've had with the TSX...but its got me thinking about the 270 wsm I'm waiting for. Barnes makes a 110, and a 130 TTSX in .277, I'm going to have to try some of each. I was thinking 130 TSX before, but a 110 would scream out of the barrel for deer, hell even a moose wouldn't stand a chance with it. I'd like to try some of the 130's which would be a great round out of the 270 wsm for bigger tougher game.

Good Point.

A bullet gets its energy from the square of its velocity....I was wondering what would happen to the 130's performance on a longer range shot where some of the velocity has bled off?
I am also concern about what happens to the momentum of a 130grain bullet when you loose a couple of petals?

Omega,
I picked a black bear as a target because they are in season and a good candidate for an explosive bullet.

The 30 cal 130grain should be compared to the 100grain .277....They have the same sectional density and all else being equal they will penetrate the same.

Still like the choice?

Yep still one very dead bear. I have my own idea's on the value of sectional density when relating it to non traditional bullets such as the Barnes. I also don't put much faith in energy figures either. Any fast bullet out there is developing 3000 fpe or more. Think about that I'm supposed to believe that there is enough energy in that bullet to do the work required to move 3000 pounds one foot in the direction of the force. So how come a 300 pound deer that the bullet stays in doesn't fly backwards 10 feet?
It certainly highlights the fact that any expansion while reducing penetration is helping transfer all that energy.
