The .376 Steyr

By Chuck Hawks

.376 Steyr
Illustration courtesy of Hornady Mfg. Co.
Hornady and Steyr introduced the .376 Steyr in 2000 as a joint development. Steyr initially chambered the .376 in a big bore version of their Scout Rifle with a 19" barrel. (Shades of Remington's .350 Mag./Model 600M combination of 1964!)

Hornady factory loads come with 225 grain (BC .320, SD .229) and 270 grain (BC .380, SD .274) Spire Point Interlock bullets. The 270 grain bullet is loaded to a nominal muzzle velocity (MV) in a 24" test barrel of 2610 fps with muzzle energy (ME) of 3990 ft. lbs. The 225 grain bullet is a reduced power (and recoil) load and also features an advertised MV of 2610 fps with ME of 3325 ft. lbs.

According to Hodgdon reloading data, handloaders can equal the performance of the Hornady factory load giving a 270 grain bullet a MV of 2610 fps using 65.5 grains of VARGET powder, and achieve maximum velocities of about 2910 fps with the 225 grain bullet in front of 68.5 grains of H335, and 2388 fps with 300 grain bullets in front of 59.5 grains of H4895. All loads were developed in Hornady cases using Federal 215M primers, and all loads developed pressures right around 60,000 cup. For African conditions, where excessive heat can cause considerable increases in chamber pressure, it might be wise to reduce those loads.

The Sixth Edition of the Hornady Handbook of Cartridge Reloading shows that 59.4 grains of H4895 will give their 225 grain Spire Point bullet a MV of 2600 fps. 56.3 grains of the same powder will drive their Spire Point or RN 270 grain bullets at a MV of 2400 fps. These would be more reasonable hunting loads in much of sub-Saharan Africa. These loads Hornady cases and Winchester WLR primers and were developed in a 25.5" test barrel.

Note: A complete article about the .376 Steyr can be found on the Rifle Cartridge Page.

Legistine actu quod scripsi?

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

A man of your knowledge, I am surprised you use an Apple!

I use an iphone, and an ipad, but I refuse to use an Apple computer.

My wife and daughter do.

I don't.

Apart from laptops, desk computers I have here are all built by myself.

Learned about computers the same way I learned about reloading.

By doing it yourself.

Generally, on a PC, you get a choice of leaving the "unsafe" site, or continuing to it.
