Home Forums Reloading Big Game Rifles 375 H&H loads with Barnes TTSX

HI - Looking for load data to use in a 375 H&H with the Barnes 250 GR TTSX bullet - Rifle is a Rem M700 XCR 11

Thks RJ

No one loading the Barnes 250 TTSX in the 375 H&H EH ! LOL

Cheers RJ

I don't know about the 250s, but a stiff dose of RL15 behind a 270gr TSX has a reputation as a tack driver.

+2 on R15 and the 250s but work up slowly there was a big discrepancy in the max data from the different manuals and different 250 grain bullets. About a six grain difference if I recall correctly.

Some checked out fine in cool weather only to be too hot for hot weather. Had to disassemble what I thought were good loads.

I see some guys are using up to 78 grs of RL15 with a 250TTSX bullet !
Whats your opinion ?

Cheers RJ

78 grains is my .375 Weatherby load. Work up in your H&H, for sure. (75 grains more likely...)

I use 74gr RL-15 with 270 TSXs. Great accuracy and no issues.

Hey RJ, call TY at Barnes, tell him what ya got, and he'll point ya in the right direction with several different powders, and maybe even a good one you already have on the shelf.

Thanks Guys ! TJ from BARNES sent me load info etc without even calling him - very good service - he must be on here in the background also ! LOL

Cheers RJ

Fellas,

How are those 270 tsx bullets on game at < 50 yards? Specifically, working on the initial stages of a black bear hunt in northern NH this fall and am wondering about this.

thanks.

Bluefish, choose your path to the vitals, that bullet will get ya through 'em on any Black Bear.

And good luck on your hunt.

Little brother what getting nice things outta 71.5gr. of '15 and the 300 TSX....

Been shooting 250 gr bullets(not Barnes) in the 375H&H since the 80's sometime,at first with 4064 but later found RL15 to be a bit better.Don't recall when I started with R15,but my top load in my rifle is 77-78 gr with Fed 215 primer in WW brass for a bit over 2900 fps.Primer pockets stay tight and I have run the same load in several 375's with similar results.

Recently did the same with RP brass as Winchester stuff dried up.....works well.

Obviously work up to this,and a good idea may be to get some 250 Sierra's for initial workup,and as an accurate and cheaper practice bullet. You will maybe find the Barnes and Sierra's go the same place,and can be interchanged without rezero.

Follow the good advise above to work up to these levels and be safe.

Still looking for other peoples loads with the Barnes 250 gr TTSX in a 375 H&H RJ

Start with 75 gr 4895 and Federal magnums. Max is probably 78-81 gr.

I use 78gr of RL 15 w/ a 250 TTSX in my .375 HH XCR II. I shot a moose this year (details in General Big Game forum) using this load. I tried other powders, but this one worked very well. I get 2824 fps, but one of the shots went into its chest and came out at the last rib!

I have been loading 77-78 gr RL15 with the 250 Sierra and Bitterroot for quite a few years...no issues in an Atkinson and Krieger barrels,and with both WW and Rem cases.Pretty standard stuff.

But things may be different with a Remington barrel and different bullet.... and I would drop back to 74 gr and work back up. I would stop when velocities hit 2875 or so.

Here is some data from loads I worked up 2 weeks ago in my M70 Classic Stainless for a reference.

Barnes 250gn TTSX / Reloader 15 / Fed215 / Nosler Brass / NO crimp

73.5gn - avg 2695fps

74.5gn - avg 2745fps

75.5gn - avg 2785fps

76.5gn - avg 2801fps

77gn - avg 2833fps

That seems about right to me....77 gr gives me 2880-2890 from a 24" Krieger 410 SS barrel.

I am still trying to find "the load" for my 375 R. Started with R17 and the 250-gr TTSX and worked up to 82-gr getting 2900 fps out of my Ruger's 23" barrel. Not an H&H though and started with the Alliant powder 'cause I have a lot of it and use it in three cartridges now. Have only shot a couple of groups so far but am getting little triangles of just over an inch.

May give you a reference point since these cases are so close in capacity.
