Home Forums Hunting & Shooting Express Rifles and Big Bores Only .375 H&H bullets

I'm staying away from those damn hearing aids. At least that way, I'll have a good excuse!!! ... Going on my 19th. year of marriage so I need all the help I can get

Actually it was my wife,kids and my parents who finally put their collective foot down.

Still have "selective" hearing.


BSA,as far as the hearing aids,they are good until I'm around very loud things,then not so much.

Congrats to your wife for putting up with you for almost 19 years.

Got back from shooting the .375 H&H and the .338 Win.

The .375 H&H with 76.5 grs IMR-4350,Rem 9 1/2 mag,260 gr NP shoot the best. About 1" or a little less at 2595 fps average,gonna load some more of these and take them out to try again next weekend.

The .338 well,may try RL-19 next with the 250 gr Sierra or try a different primer with IMR-4350,like a WLR or CCI-250 mag.

Ha ha. She's a damn fine woman and really deserves some kind of an award!!!!!! Cool that you finally got out and shot your 375 and 338. I was beginning to wonder... . Hey by the way, use the CCI 250's...With the 338, start at 67 grains (IMR 4350) and work up 1/2 a grain at a time. Seat the bullet .020" off the lands and you'll find a good shooting load in no time... Here's how my rugers always shot:

Yeah,she does.

Thanks for the info amigo.

Shoot the 260 gr NP,76.5 gr of IMR-4350,Rem 9-1/2 mag primer and it shot into a 1-1/4" group,so I'm done with "load developing" as it will do for whatever I want to hunt with it.

I shot a 54" bull moose that I called in. I shot him in the chest and exited the last rib w/ a .375 hh using the 250gr TTSX. Love that bullet!

Have wondered about that 250 gr ttsx since it came out Green, I have a pile of 270 gr tsx's and my rifle loves em, will even shoot em a bit over an inch at 3100 fps in my 375 AI, I've backed em down to around 3K and they shoot even better.

gunner500,
I have similar experience as you with my AI,and will be experimenting with the 250TTSX this summer because of the much better BC. Perhaps we could share info,depending upon who gets the work done first.I probably won't get started until July,as I like to developers loads on "hot" days! I'm hoping for 3k or better and 1/2" to 3/4" 3-shot groups. memtb

10-4 memtb, you can easily get to 3K with the 250 gr ttsx using RL-17, my rifle is a M-70 with a 24" barrel, agreed on the hot weather workup, especially on medium to big bore rifles that may be taken to Africa and put into service on or around dangerous game.

gunner500,
I finally found some RL17 several years ago,and it's everything that I could ask for in a powder. Real good velocities and the best accuracy of all I've tried. I also did a test at sub-zero temp's(left rifle and ammo outside several hours before test), and according to my chrono,actually gained 9 fps. And,got my best 300 yrd(sub 2") 3 shot group. All in all a very good test day. memtb

Now that's what I'm talking about.

Mirrors my results to the tee.

Gunner,

What's a good RL-17 load, 250 TTSX in a .375 H&H, not AI?

ElkhunterNM, 2595 fps seems a bit slow for the 260 Nosler out of the .375 Holland. That's almost .375 Winchester performance. My hunting loads with 300 Noslers run around 2575 fps with W760 and N204.

Does your accuracy go south when you speed up the load? And did you find pressure issues pop up when you went faster?

I'm not being critical, but I just bought 3 boxes of 260 gr overruns from Nosler's Pro Shop, and judging from the load data, a guy should safely be able achieve around 2850-2900 fps with that bullet.

I'm going on a coastal grizzly hunt this fall and was thinking that I'd try the 260 Noslers, providing they shoot well....

As the speed went up the groups opened up and no pressure issues. I'm a little disappointed in the speed,but not to worried about it. It's only 100 fps slower than I want and there's not a animal in the world that is going to know it's 100 fps slower.

In my other .375 H&H I use a 300 gr Sierra GK,H-4350,Rem 9-1/2 mag and it's getting 2630 fps.

Good luck on your coastal grizzly bear hunt.

Don't know DF, haven't played with any of the 250's yet.

Mine loves 75 gr. re 15 and 270 gr. TSX's damn near a one holer! Probably one of the most accurate rifles out of the box I have ever owned. Model 70 classic stainless 375 HH. As always work your loads up from proven data.

I keep seeing reports on the superb accuracy of the 270 TSX vs. less than stellar reports on the 250 TTSX.

My Ruger Magnum loves 300 grain Swift A-frames. I see no real reason to use anything else that needs whackin' with a 375 H&H.

Can't speak to the TTSX as I have only run the TSX. They shoot so well I was not even planning on trying anything else.
