Just got a Win M70 Classic Stainless in 375 H&H and was wonderoing about loads for it. Although I will use it on whitetail deer there is always a possibility of going after larger game. I was looking at the Nosler 260 gr Accubond and Partition as an all round load (one load/one point of impact) for everything. Looks like I can get them up to 2700/2750 with reasonalble loads. But the bullets aren't cheap so also looking for a less expensive practice/plinking load - maybe cast bullet or ???
Comments, suggestions, opinions, and other loads welcomed.

Try these bullets.
Nosler- Shooters Pro Shop

Buy the accubonds and Partition seconds. They shoot great in both of my 375 H&H rifles!

I shoot a lot of 330gr cast bullets for practice.

I also shoot 300gr woodleighs and North Forks with H4350.

Expensive bullets are not necessary if whitetail are your primary target. I use cast bullets in my 375, a 260 grain flat point at about 2100fps. That load has enough power and shoots flat enough to make a 200 yard shot no problem. I cast my own, but I think there are commercial cast available.

Buying commercial cast bullets doesn't save a lot of money compared to the cheaper jacketed bullets. Hornady makes 270 & 300 grain round nose bullets that are economical. The 300 is available in Interbond for $15.53/50 from Lock, Stock & Barrel (I just got a new catalog.) Speer makes the 235 that should make a good whitetai bullet. If it were me, I'd keep the velocity on the low side on all these bullets. You don't need that much power for the game you're after and you don't need the extra recoil. Loading manuals show the 235 Speer up to about 2900 FPS, which IMHO is too fast. Keep it down in the range of 2500-2700 FPS and it'll work fine. The same with the 270 and 300s, keep them 100-200 FPS below what the manual shows as maximum. Your shoulder will be happier and the deer won't know the difference.

Even at 2600 fps the Speer 235 gr leaves a trail of fragments in the wound canal ... as does the 9,3 caliber 270 grain bullet in pigs and whitetails.

Speers are good for paper, but not much else.

Rusty Thanks for the info I was un aware of the Nosler Factory 2nds. availability. I will persue that avenue, while considering all the good info.

In my Sako 375 H&H I tested these Speer 270 gr bullets going 2612 fps, Hornady Flat Base 270 gr bullets going 2620 fps, Serria BT 250 gr bullets going 2720 fps, and Serria BT 300 gr bullets going 2648 fps. These bullets are not loaded for Deer.

I would recommend the 270 TSX. You can drive it fast enough to match 30-06 trajectories and it should be up to any task you might have for a 375. The TSX lierature suggested 1-2gr. over max with the regular Barnes X. I tried one grain over and got 3/4" groups at nearly 2800 FPS with R15. Load development over right there.

I've had good results with 260 Noslers partitions in my Mod. 70 in stainless. I've had the barrel cut to 22 inches. I used 66.0 and 67.0 grs. of IMR 4064. Both loadings have shot under 1" five shot groups off the bench at 100 yrds. The average velocity was 2503 for 66 grs. and 2535 for the 67 grs.
I've also shot 76.5 and 77.5 grs of IMR 4831. The group opened to just about 1.5" No velocitys measured for these.
I've also loaded 74.5 and 75.5 grs. of IMR 4350. Groups opened to two to two and half inches. Velocitys were 2476 with 74.5 and 2515 with 75.5 Velocitys were the average of five shots. I had nearly idenitcal results using the Nosler B.T's in 260 grains.
Your velocitys will likely be higher with the 24 inch barrel.

I´ve tried Speers 235gr bullet for deer and they usually separate/blow up. The load was on the hot side which might be one explanation. On the other hand I loaded Hornadys fast and they´ve preformed nicely. Use the Speer for plinking.

I was shooting my 375 H&H this morning. These are two consecutive groups shooting the 260 grain Nosler Partitions (2nds from the ProShop) and 80 grains of IMR4350.
This load has no signs of high pressure in my gun and the cases are filled to the bottom of the neck.
I haven't chronographed this load yet because the range was to full of newbies this morning.

I have to second Mark's post -- my experience is remarkably similar, right down to the powder, and resulting velocity and accuracy (the latter for as long as I could concentrate through the recoil, anyway!

I've only shot one bull moose with this load, but there were centimetre-sized fragments of lung all over the shooting place. Still, less meat damage than I've come to expect from my 7mm Rem Mag.

Based on some informal penetration and expansion tests, this load would be hard to beat I think -- rapid initial expansion, then a lot of penetration.
