Home Forums Hunting & Shooting Ask The Gunwriters .375 H&H w/ 300 gr TSX - Question for Mule Deer

One more thought. Barnes lists Big Game as giving the highest velocities with the 300 grain TSX. Has anyone used it in the .375 H&H?

Seems odd that he loads the 300 faster than the 270?

From my reloading book and actually it's a load given to me by our own JJHACK. All I can tell you is that what my Model 70 turns out. And no issues in Africa and besides, unless you hunt far into the middle of September and beyond, Africa has some lovely temps in June-Aug. In September it did get to about 105, but I never had any trouble.

Thanks Jorge!

What would you shoot with the 300 that you'd not shoot with the 270?

Guessing that there isn't much.

I prefer the 300 for buffalo. For everything smaller, the 270 may be better. Those are just my personal preferences. Obviously the 270 will work on buffalo as well.

Jorge, just curious, did you chronograph those two loads on the same day, same light conditions? Do you have a theory as to why the 300 grn bullet had higher velocity? Those numbers seem like an anomaly don't they?

But speaking of anomalies, jpw advocating for a lighter bullet!

I'm an IDIOT. I transposed the numbers. Sorry!

I might be a recall from the days gone by. I still use heavy for caliber bullets in most rifles, except varmint rifles. (I admired Elmer Keith.)I've had issues with too lite of bullets, but never too heavy.

250 grain Nosler Partitions in the 338 for instance. Why because they always work and if they work well I don't mess with things. I use 180 grain bullets out of the 06 on deer too.


HOWEVER, on a prairie dog hunt I just had over the last week I found that 275 grain bullets in my 375 H&H AI over-penetrated, as did 240 grain 44 magnum bullets out of my Ruger SB.

So next year maybe on the 375 I might drop to 270 grain bullets.

OK, I mostly shot 6mm 75 grain and 223 55 grain -- I didn't take out the 204 because the wind was tremendous and the 204 was loaded with TOO LITE bullets 32 grain. I also didn't shoot lighter bullets out of my 6mm.

On this trip, I talked with a cousin who goes to Africa regularly and he talked me into going with him next trip.

I'm only interested in shooting a buffalo and am considering using a 416 Rigby or the 375 mentioned above. Interesting reading about the 300 grain vs. whimpy bullets.

In mono metals the lighter bullets to a point have proven to be about perfect. I called Barnes yesterday and Ryan to,d me that the 270 grain TSX shot from a 375 H&H would slightly put penetrate the 300 grain TSX and that is my experience as well.

jpw, there might be a typo in your last post. Did Barnes tell you the 270 grn should out penetrate the 300? Just want to make sure on this. I just got a new .375 and just starting load development.

No typo. He said if fired out of say a 375 JDJ the 300 grain would penetrate deeper, but shot out of a 375 H&H the 270 grain would penetrate deeper

Hmm. That may be true in "media," but in my experience lighter-for-caliber TSX's (and similar bullets) tend to get stopped by hide more often than heavier ones. Which was apparently what the African PH's were talking about when they said 270's didn't exit as often as 300's.

I've done a considerable amount of bullet testing in various kinds of media, including 9.3mm 250 and 286 TSX's. The 286's outpenetrated the 250's, even though the 250's were started 200 fps faster.

Thanks for clearing that up jpw, but check your post again. I think you just typed a "p" instead of an "o". I'm not nit-picking, just want to make sure I understood your meaning.

Heads up guys, I just found 300 grn TSXs on sale at Cabela's for $36.79 per box. That's less than they sale Sierra Gamekings of the same weight for.
