Home Forums Hunting & Shooting Africa TTSX 250 grain .375?

Anyone use the TTSX 250 grain .375? What results? How does it compare with the 270 TSX?

I heard it works real well but I have yet to load some up and try them out.

I used the 250 TSX in my 375 H&H and they worked well on two plains game hunts, figured 270 grain wasn't necessary for zebra and smaller. I have some recovered bullets that I've posted here in the past. I don't have any 270's for comparison.

I have 50 of the TSX loaded if you want to try a handful.

Have not used them, but being a TSX fan the TTSX will work well if it shoots well in your rifle.

I've loaded them in front of 75.5 grs. of RL 15 for my Remington 700 KS 375 H&H. I get 1" groups at 100yds. I may bump that up to 76 grs. I don't know how fast they are going though. Kevin

Thanks for the info.

Boise,

Thanks. I picked up a box of fifty.

woods1126,

Ty, at Barnes, told me he checked the accuracy from their tests. He said 1 1/2" for ten shots at 100 with their TSX .270. Can you believe the TSSX 250's group was 7/8" for ten shots. Apparently the barrel liked them. I hope mine does.

Ringman, Those groups are awesome. My groups a 3 shot. I can't imagine 10 shots with the 375 in 7/8 inch! It must have been one big hole! Kevin

You have 5 rounds of .235 gr. TSX on their way. The load data is in the box.

79 grains of R15 and a 250ttsx gives exactly 2900fps over my chrony. It also turned in a 4 inch group at 320 yrds that was 3" below POA (3" high at 100). the load and gun may do better but I cannot.

Moose have shown a very strong dislike for this load (bang-flop) so I'm pretty sure similar sized african critters will as well...

I'm liking what I hear about this combo, kinda like a faster 338 win mag with a little more power on tap.

There is one distinct advantage with the 270

Those who have used the 250s on plains game with great success are correct. It is brilliant. About like a 338 but bigger holes.

The 300s are better for the biggest African game then the 250s.

There is the advantage of the 270. One weight easily handles both duties. It's fast with enough mass and penetration to handle anything you see better then either the 250 ( more mass) or the 300( more speed)

The 270 is the best choice

With Africa in mind yes a 270 gr would be better. For what I may do the 250 will probably be fine. Since this is the Africa forum.

Only thing in Africa, at least RSA as big as a normal Moose is an Eland, and a big one of those bigger. Kudu more in the 5-600 lbs class, and everything else smaller. Probably 80% of planes game as small or smaller than a whitetail. I've taken a 280 or 308 the last 3 trips there, and never felt undergunned. Not saying you shouldn't take your 375, and the 250gr load sounds like a winner, but not really needed.

It's the capacity of a herd animal that is much different then deer.

Kudu are much like deer in the will to live and escape wounded.

Wildebeest gemsbok zebra etcetera are the strong willed. They travel dead on their feet. They cannot be compared only with body size.

I doubt that there is much if any difference in penetration with the 250 compared to the 270, 300 grain TSX bullets on game.

I can only respond based on the recovery of the bullets.

I've recovered a handful of 300's

Maybe 10-15 270 grain

And probably 30 or more if the 250 grain bullets, most of which were just shanks without any petals remaining.

The 300s retain the petals nearly all the time. Exceptions being very close range very big animals.

The 270s retain petals more often then not but frequently are missing one.

The combination of 200 plus fps additional velocity over the 300 gr with that 270 grain bullet gives it astonishing performance

The mono metal expanding bullet do seem to thrive on velocity, don't they

The 250TTSX adds versatility to one of the most versatile calibers. The advantage of the higher BC does not come into play versus the other weights available until somewhere beyond 300 yards. If you are planning to hunt where long range shooting can be expected, you can load them up to max velocity.
OTOH if you are hunting lighter game and expect closer shots, you can load them down to 2700fps or so and enjoy a bit less recoil.
They won't and shouldn't replace the 270's, 300's, 350's, etc. but they just add another arrow to the quiver.

Forgot I had these images of the 250 TSX performance on a bison. The bullet was recovered against the off side hide, shot distance was less than 100 yards, 2822 fps muzzle velocity . This was a depredation hunt along Utah's Green River.

Nice shooting! I would have expected more trauma to the heart at that impact velocity.
