7 mag Barnes 150 TTSX Anyone load this?

[jeff_gibbons]

Hello all,
I’m working up a Barnes 150 gr TTSX load out of 24” barrel and getting about 3,050 fps with IMR 7828. And just under 3,100 with RE22. I’m 50 thou of lands.
Anyone find a good powder combo for this bullet? What kind of velocities did you get? I was hoping to get a little better than 3,100 as get 3k with a 168 gr berger.
Thanks in advance.
Jeff

P.s. I’m aware of accuracy > speed

Thats actually pretty good speed. I get 2900 out of 2 7mm rem mags. However both those rifles shoot extremely well. At that speed it will still preform and expand at 600 yards at the elevation I hunt. Would I like more speed??? Sure would but neither rifle will do it.

They will with a 143 Hammer. mtmuley

I do not shoot a 7mm mag.
I do shoot MANT different chamberings of Barnes bullets.
Most notable is my 8mm RM.
I use a tsx 200 gr and use RL 26 I get a one-inch group at 200 yards and muzzle speed of 3200 fps checked with a Magnetospeed. 50ish off the lands too but because I run out of room in the magazine.
If you can get some RL 26 you will be amazed at what you can get.

I got a bunch of Sledgehammers in 200 gr, I don't get much more speed than the Barnes, A little bit.
But the Barnes are a bit better groups at 200 yards.

My 280AI with a 26" barrel will push this bullet a little over 2900fps with pretty good accuracy - about .75MOA. This is using Reloder 23, however, which seems to about as easy to find as pterodactyl eggs these days.

@JohnCushman has load data for that rifle combo. If I remember correctly I used rl26 and it was around 3150fps.

That is my current go to bullet with my 7mm. 3037 fps with 63gr of RL-22. Very accurate out of my gun. Found this load to be very consistent and accurate so haven't really pushed for more speed.

I have been getting consistently better numbers out of both H4831SC and H1000 vs RL22 for my 150 gr Hornady CX. My sweet spot right now is the 4831SC with a measured velocity average of 3155 fps and 0.55 MOA at both 100 and 200 yds. Rifle is a Kimber Mtn Ascent.

Will be loading some 131 Hammer Hunters for the 7 RM #1 26"bbl soon...

It shot 130 TSX and 140 TTSX well...will check load data and recorded speeds.

I think you're on par for a 24" barrel. My 7rm is getting 3150 with a 162 ELDX with imr 8133. But it's a 26" barrel.

 

[Robert N]

I’d have to check my data but IIRC, I got 3100 fps with H4831SC. I used that 150gr. TSX in Africa, taking 8 game animals from Impala to Eland (that’s about 80# to 1800#). Blue Wildebeest, Zebra, Oryx…

Admittedly, the Eland did take two shots…the first shot shattered the top of the 4” thick humerus (I Mean, totally shattered it, like a grenade went off - shards of bone everywhere), broke a rib and penetrated to about 2” from the heart. The second shot, a high shoulder, broke the spine and finished the job.

The Zebra took 28” of penetration, stopping on the far side after a breaking a rib, punching through the lungs, breaking a rib on the other side and stopping just under the skin on the far side.

I wouldn’t sweat the velocity.

Thanks all.

I've shot hammers. And my one 7mm rem mag will just make the 3000 ft/sec mark. But after shooting a couple animals I'm not that happy with the performance of the bullet and am switching back to the TTSX or may try a CX.

 

[Alpine01]

Thanks all.

Good luck. Let us know how your load development works out. I am curious how the TTSX pans out for you as it was one of the bullets I considered.

Which Hammer? What happened? mtmuley

143 Hunters. Bullet worked as advertised. But I don't like the .284 exit hole. I hunt thick stuff and like a bigger exit hole. That is my only dislike about them.

How far was the recovery? I took a whitey last year who ran a good ways into the thick with 1/3rd of his heart missing from a 45cal 325g flex tip...have had dead hogs running from good hits also.

I get what you're saying tho, I have the same lack of affinity for Bergers but full faith in Hammers.

I rechecked my data today, my 143 hammer hunters are going 3100. I couldn't get a TTSX going over 2900, my bad. Son shot a mule deer buck, at the shot it did a 90 degree turn and stood there, so he shot it again. It stood a little bit and started trotting down into a ditch so he shot it again and hit backstraps, dang. Upon processing the buck both bullets passed thru, one from each side. 4 holes at .284. Lots of copper bits just under the hide. Buck was shot thru the ribs just behind the shoulder. I shot at a cow elk with the same load, 200 yards. She was standing and at the shot lots of other elk bolted. I never recovered this cow, had snow and never any blood. Spent all day and some of the next trying to find it. So either I clean missed or no blood. But this left a bad taste in my mouth. Would a bigger exit hole helped??? Don't know because I can't duplicate the shot. After watching my sons buck thru the spotter when he shot it I was surprised at the bucks reaction. My son thought he missed both times. This year we shot 4 elk with TTSX bullets in 7mm rem mags. All one shot kills and all only went a few yards and went down. Nice exit holes and jello lungs. Would I use hammers in more open county?? Yes

With the 150gr TTSX best results for me was using IMR 4350.
