Anyone mess around with the 270 TSX in their 375 H&H?
And if so, kill anything with this combo? Looks potent! I'm ready to try these bullets in my new 375 H&H.

What powder are you guys getting the best accuracy with?

Yes,

I've killed elk, warthog, wildebeest, blessbok, and tons of feral hogs with this combination.

Two things,

1. It is scary accurate out of my .375H&H I use an almost (published) maxed out load of IMR 4320 pushing the 270gr TSX 2700+ out of my 20" barrel. These bullet regularly shoot under 1/2" and I've got a couple of groups in the .374" category. In other words one hole 3 shot groups.

2. I've yet to have a TSX not just knock the crap out of anything I've hit with them. They are impressive and they usually exit. I highly recommend them in the .375 and the 270gr weight.

Including feral hogs I've shot somewhere near 100 head of game with the TSX in both .375 and the .308 selections. I've yet to have one do anything but give perfect performance.

I have however read some B.S. about them on the net. I seriously doubt however you'll have any problems with them.

They should be about the most perfect combination on the planet for your home state. excellent B.C. awesome construction and very impressive terminal performance.

I'm taking the 270gr TSX to Canada for moose in September.

74.0gr of RL-15 gives right at 2,700 fps in my 2 rifles with accuracy of 1/2" to 3/4" at 100 yds. Same results in my buddy's 2 .375s. We've tried a bunch of different powders with this bullet and RL-15 gives by far the best accuracy and consistency in all of the rifles we've tried it in.

adrook,

Is that max charge, or do you know? Is it possible to push those 270 grain bullets at near 2800 fps?

270gr bullet at 2700 fps yields just about 4375 ftlbs of muzzle-energy ---- what do you plan to shoot that needs 4700 ftlbs?

Moose-Hunter,

It is not a max load according to the Barnes manual. Barnes shows 76.0gr RL-15 with the 270gr X-Bullet as max in their manual. According to them max for the TSX is 1.0gr to 1.5gr over the max for the standard X-Bullet. I would think that you should be able to get 2,800+fps with RL-15 and the 270gr TSX without any problems but you would need to work up to it. The 270 TSX with RL-15 is a very accurate combination.

As an aside, I just shot a group with my M70 .300 H&H Mag with the 168gr TSX and 69.0gr RL-19 at about 3,100fps that measured .067" (that's not a typo, measured side-to-side widest point with a dial caliper deducting bullet diameter of .308") for 3 shots and the worst group I have shot with this load is .50". Needless to say that I am thrilled with this load but when you push it to 70.0gr or more accuracy goes to hell although velocity is higher. The TSX bullets are very sensitive to barrel harmonics and seating depth, it's a very fine line between super-accuracy and acceptable accuracy with them. For me I will take pinpoint accuracy over a couple of hundred fps anyday. Overall, I am really sold on these TSX bullets.

While We have Tsx users here, can you tell us the length of the .375 270&250gnTSX?

Moose, I used the 270gr Barnes TS bullet last year to kill a cape buffalo in Zambia. It worked great, two shots. I used 74gr RL-15 with the bullet seated .050 off the lands. Shoots close to 1/2 inch groups. This bullet was used to take a puku (deer size ) and a hyena. The bullet opened up even on these light animals.

Don't have any of the 250gr bullets but the 270 gr TSXs are .366" long.

That .366 is gotta be a typo! Is the length REALLY shorter that the bore size?

homerSorry, that's a typo. I meant to type 1.366".

I've used the 270s in the 376 steyr... one HECK of a pig and jug round... good accuracy, as well.

I want to try the 235s!

Second that comment based on 8 Namibian animals last month. 6 of them didn't take a step. See my post in "African Hunting Reports" for details and bullet pics.

I think my rifle has a tight bore and as a result will not shoot the TSX bullets well at all.

Forgot to mention -- I use RL-15 at about 2700 fps.

Jeffe,
Have used both the 210gr X and the 235gr TSX on large elk here in Colorado. Fantastic! DRT.

As many have said in the posts before, I have found that in my rifle, between 73.0gr and 74.0gr of RL-15 with the 270gr TSX shoots extremely well. The velocity is around 2650fps to 2700fps.

RL-15 appears to be the powder of choice. I have a can of that powder already waiting to be poured into some 375 H&H cases. How are you guys figuring out what the max load is for this powder and TSX combo?

Prof,
I am thinking the 235 TSX in the steyr is as perfect as mash potatoes and gravy, or beer on a hot day!!

Hope it's a big can, since a pound won't even get you through 100 rounds...

I checked a bunch of manuals for max. loads. Hornady, Nosler, Barnes, Alliant and Lyman all showed max loads of 73-76 grains and about 2650-2750 fps. 74 gr. gave me 2700 fps and excellent accuracy with both the TSX and the stand-in 270 Hornady (which I bought several hundred of on one of Midsouth's blemish sales).

Update. Been to the range a few times shooting my 375 H&H with a bunch of different powder weights of RL-15. Just about anything from 74 grains up gave me some outstanding accuracy, minus my 75 grain and 75.5 grain loads (is that weird or what?). I don't have a chrony but need to get one. I settled on 77 grains of RL-15 for my 270 TSX. Pretty much writing this off as max load with great accuracy. Ready for spring brown bear.

I've used the 270 gr X in my Weatherby Mk V Weathermark Alaskan. Believe it or not, 71.0 gr of RL-15 gives 2604 fps. The rifle shoots just over an inch at 200 yards.

My M70 SS Classic throws 300 gr TSXs at 2600 with 69 gr of RL-15 but only holds 1.25" groups at 100 yards. Recovered a perfect mushroom from a Hartebeast shot in the left rump. Bullet came to rest in the front of the chest wall after traversing the entire animal left to rightish. Only .375 X or TSX I've ever recovered.

Fine bullets these.

74 grains of RL 15 is a great load for the 270 grain TSX. I get 2800fps out of a Blaser R93 barrel and it shoots .4 inches at 100 yards.

The 180 gr TSX in 30-06 at 2,600 fps works great on kudu. Now that the supply of Barnes bullets have been secured in RSA, I think this bullet will gain a following in the most widely used caliber in what we call the old Transvaal.

The .375/270 gr TSX will no doubt follow the same path.
