Guys,

Have a practical build .376 Steyr ready to blue. Is a 22" Douglas bbl on a 1909 Argie.

Intended this one for North America as I have an M70 SS Classic in .375 H&H that has performed well in Africa w 300 gr TSXs.

Thought that the 225 gr Hornady SP might make a decent bullet for the Steyr for most things here.

I suspect it is perfectly possible to drive the 225 too fast for its construction with the Steyr cartridge.

Anyone have any sense of what is a reasonable maximum velocity for that bullet?

mstarling, Hornady offers two loadings in 376 steyr. The full trottle 270 grain inter-lok and the 225 grain inter-lok "reduced" loading both at 2600 feet per second. The 225 will hold up find at that velocity and I would not hesitate to use it on elk size game just like I would not hesitate to use a 150 grain cor-lok in 30-06 on whitetail or mule deer. In my gun the 225 grain hits a few inches to the northwest of my 270 grain inter-loks and 300 grain partitions. The 300 grain PTs about an inch and a half below the 270 grainers so I can use both the heavy weights on a hunt without changing the scope settings. In my gun the 300 grain PTs do a solid 2400 average velocity 1 1/2 grains below max using varget. That's good for cape buffalo.

Am aware of the two factory loads for the .376 Steyr ... but I haven't bought a factory loaded round in years. Am interested in what might be the max velocity appropriate for the 225 spire point interlock projectile.

Have loaded and fired a few of them to make sure the custom scope mounts work. Must say that the little 22" barreled rifle is damn loud with H335 used to drive 225s at 2700-2800 fps. Had not expected that much noise.

Just checked a few commercial loads on midway, could only find the 235's. However, some are driving those as fast as 3100fps from the H&H, most in the 2800+ range. I don't see 2700-2800 being a problem with what you want to do.

225gr hornadys are 2900+ are possible.. 2800 is easy, and 2700 will kill most of anything in na

This should be good for everything but Elephant and even then still ok.

OK ... didn't ask the question well. I know I can probably get the bullet to over 2800 fps from my 22" .376 Steyr barrel.

Question I have is how fast can I drive the 225 gr Hornady and have it hold up on impact with game no closer than 50 yards?

Is the bullet sturdy enough to allow loading it as fast as I can push it accurately, or do I have a velocity limit due to its construction?

I think in this chambering I'd probably use the 260 Nosler partition if I wanted a slightly heavier bullet for NA or a 270 gr TSX for larger plains game in Africa. Personally I would prefer a .416 or larger chambering for Buf.

Thanks!

Mike, I am going to load up some of those bullets for use next year in my 375 for deer and pigs.
I am going to start out holding the velocity at around 2500 to 2600fps, depending on accuracy.
