handloads for .375 H&H

I've just purchased a pound of IMR4064 and some Hornady 300 grain RN Interbonds for use in my M70. I'll be trying them out tomorrow at the range!

The IMR site lists 67.0 as max for this propellant with this bullet - anyone have experience with 4064 and 300's? Any "Pet" recipes?

I know I asked about .375 loads awhile back, but I can't find my notes taken from here and your responses...sorry if I'm possibly asking repeat questions.

I used to shoot the Hornady 300gr BTHP, but with W760. No pet loads for 4064, sorry.

Have you shot any game with that bullet? It was very accurate in one of my .375s too, but testing it on wet newsprint turned me off that bullet for good. I was chronographing them at ~2650 fps and shooting into wet newsprint at 90 yards. The bullets harldy opened at all. What would happen at 200 or 300 yards? I don't know because I didn't bother to test them after their sad performance at the closer range.

IIRC Whynot? had some problems with the 250gr TSX on game and has since abandoned them.

Crap. Looks like the "grail" has a little rust on it :( I've only used 300 grain Partitions on game with obvious success but thought I'd try these new-fangled all copper bullets. I think I'll yeild to your experiences instead of finding out the hard way that these are too tough for N.America game.

Thanks for the heads up!!!
 
Beaver skin,

I'd try shooting some game with those 270 TSX's if they shoot that well in your rifle...many people swear by them!

Beaver Skin,
I took my .375 H&H to South Africa this summer loaded with 270 grain TSXs. The one bullet that I recovered in a Gemsbuck weighed 269 grains, expanded perfectly and penetrated 4 feet. Ten animals of various sizes isn't a huge test, but I wouldn't be afraid to use that bullet on anything that an expanding bullet is appropriate for. My load was 77 grains of H414, Federal 210 primer, and a 270 TXS flatbase seated .030" off the lands. Shoots great, and nothing comes back to life either.;)

Now that I think back a little harder, I do remember the discussion about TSXs in the 375H&H. Didn't one of you (I think it was you 1899) contact Barnes about the less than favorable results??? IIRC they said some changes were being made to the bullet???

Ted where are you? Please post the pictures of the recovered .375" 250gr X!

Taken from a woods bison shot at 125 yd. Muzzle velocity 2800 fps.

Obviously tumbled. Hit no heavy bone. Broke two petals off and turned one back towards the front.

I have used this bullet on moose as well.......... one time. Three shots all passed clean through the lungs with no expansion whatsoever. Moose died, but took about 2-3 minutes. It was in wide open situation and I knew I was hitting the bull broadside, low in the lungs, every time.

When we cleaned that moose, the lungs looked like they had been punctured with a rod, not torn up at all. I called Barnes about this and they wanted me to send the bullets back for testing.

I never used them again on anything.

I was the one that contacted Barnes. I'll try to find the email, as I can't remember what they said.

My picture is a TSX. Would you like to buy the partial box of 270 gr TSX that is sitting on my reloading bench? The reason I haven't tried to sell them until now is because if I don't think they are fit for me to use, then I don't want to pawn them off on someone else. :runaway:

However, you seem to have had good luck with them, and I hate to argue with success. PM me if you want them.:)
 
1899,
I was talking about Why-nots? picture, but what the heck. If you have enough bullets left to justify the postage I'll take them off your hands. I know all about the part box syndrome, I've got lots of those that didn't work out for whatever reason.:D

The three PHs that I talked to absolutely love TSXs for everything from duikers to buffalo in the .375. One rifle, one load for everything has a certain amount of appeal. Solids for elephant was the one exception.They do tend to shoot through the shoulders rather than the ribs.
Theres lots of good bullets out there, I'm going to load A-frames in my .416 Rigby. That is mostly because I couldn't find any 400 grain TSXs on the shelf anywhere. That's the bullet the Safari operator recomended. The amount of killing PHs see in a year staggers the imagination.:eek: Who am I to argue?:D

Edit to add blurry pictures, well I tried.;) Bullet expanded from 3/8" to 3/4". Note test media.

Dogleg,

That is what he asked me to post.

I don't think they do make it anymore. They were concerned when I told them about the bullet penciling through the moose. It became abundantly evident during the conversation that it was not the first time they had heard that kind of story.

I still am not convinced. If I have to ruin a lot of meat by breaking the shoulder to get the bullet to expand, I will pass. Partitions have never let me down on really big stuff, and Hornadys work just fine on the rest.

Actually in my 375, the regular Hornady Interlock has been just the ticket for moose the past several years.

I guess you pay your money and make whatever choice you want.

Dogleg, the regular 350gr X expanded very well in my .416 RM in both media and bears.

I'll count my .375 TSX and get back to you.
 
Why not?,
I have always thought that that the "Regular" interlocks are one bullet that never seems to get the respect it deserves. I have shot more of them than everything else put together.They work, no question about that. What I don't get is the penetration that I want, for anything other than broadside shots. That's part of the trade-off, smaller expansion for more penetration. Like you say, you pay your money and make your choices.
The 300 grain Partitions wouldn't shoot worth a damn through my 375 when I tried them, that's one of the part boxes I have on the shelf. My 300 Win mag loves the Partitions though. It's probably the bullet that everything else is judged against. Do they ever make a mess though. I don't care about that much, but some do. I do believe that softer bullets tend to kill a little faster than hard bullets when everything goes right and not much penetration is needed.

Heres a picture of a double shoulder hit with a TSX in a 375. Not a lot of meat damage, but the vitals were soup.

Xs or TSXs? If the second in 270 or 300 gr. we could do something. Actualy, I wonder how many people have part boxes of use-less bullets (useless to them) that could get to where they can used be some one else? Usually with smaller calibers it isn't worth the postage but the big stuff might be different, I have some 285 Grand slams in this caliber as well, that I'm unlikely to use.
 
285 grain .375 Caliber Speer Grand slams

The fellow who sold me my M70 in .375 H&H explained that he too had settled on the Grand Slam as his favorite hunting bullet in this caliber.
