I've heard B. Searcy and others offer this caliber
option in D/Rs. 9.3x74R brass opened .009 to use
.375 bullets instead of .366 bullets. Anyone have a
D/R in this caliber? Is the brass straight with a taper
to the mouth or is there a neck? Can it be recham-
bered to the H&H Fl Mag caliber if so desired?

If it were rechambered it would probably need to be re-regulated also. The barrel twist might not be correct either.

The 375x74R is exactly like the 9.3 case; you still have a neck; .009 is not enough to remove the neck on the 9.3 brass. Rechamber to 375FL? Why; Just order it that way to start with. But I think it would be easy to do; the two rounds are very close and it looks like the 375FL would clean up a 74R chamber. They are so close that rifling and regulation should (should) be ok. In the US, the 375x74r would have been a good idea, but it is too late now; the 9.3 is more common than it used to be, 30 years ago. Back then, bullets were so hard to get that I swaged 375s down to .366. And people were making brass from stretched 444 Marlin brass. I still have some, somewhere.

I agree with dpcd. 9.3mm bullets are readily available from Nosler etc. Is there a ballistic advantage?

And heaps of other places / makers as well.

30 years ago is not today.

And as for rechambering to 375x74R, 30 years ago they were rechambering to 9.3x74R with the ODD one done to 375FlMag because I have one of two Rigby's done to that calibre.

And why would you want to create an odd ball ?

That's a hell of a stretch. How do you do it and is it safe?

They used rotary ball bearing spinning tools of some sort; (I only bought the brass; I did not have the tools) it was safe as all you are doing is making the brass thinner toward the neck. The head and the first inch or so is unaffected. That was in the dark ages of the 1980s and there is no reason to do it now for the 9.3, although it is still done for the long Sharps brass; and some others, making longer ones from 45-70. Go to Buffalo Arms site and you will see some brass made from shorter brass.

Dpcd, Simply because the quality bullets are so easy to get today, the re-chamber that would be a lot better would be to neck the 375FL down to take the 9.3 bullets. This would allow a little more power to the rifle with that case, and give you a 375FL head stamp as well that would for all practical purposes put in the same class as the 375FL and will be a proper diameter for the barrels in the double rifle you are re-chambering! What do you think?

Hi guys. I started this thread with a couple of
points in mind. I believe 9.3x74R brass is
easier to get (over the long haul) than 375 Fl
Mag. I speak about the rechamber idea because I
believe a 375 Fl Mag would be more valuable and
sell easier than the quasi-wildcat 9.5x74R. Also,
.375 is the legal minimum in some places for DG.
Saeed's done so well with his .375 wildcat on
the 404 Jeffery brass I figured this 9.5x74R round
would be a great "fraternal" twin to that.

I had bailey Bradshaw build a single shot rifle in that caliber last year and with the custom dies I found its a fun caliber to play with but in the 6.5 pound gun it can be a bit too much. rNB

It is true that there is only .009 over with .375 bullet over the .366 bullet, and you and I know that but we are talking AFRICA here. If you use the 9.3X74R case necked up to .375 if they check your ammo,they will go by the head-stamp, not what you SAY the bullet diameter is.

Besides that the rule is not only the bullet diameter but includes the energy it develops as well, and the necked up 9.3 case to .375 would gain nothing on energy end of the equation! You know T.I.A.(~This Is Africa~)

That is the reason I suggested the 375 FL case necked down to take the .366 or even with the .375 bullet. It would give you the .375 head-stamp and would actually increase the energy with the larger capacity case!

Please don't misunderstand, it is no skin off my butt either way you go, but I simply want to make you aware of the way African officials think. They may not check your ammo at all. Actually the 9.3X74 R is legal in Zimbabwe anyway, so you could simply use the 9.3X74R double. That is my light rifle combined with my bigger 470NE double.

I had the officials check my ammo boxes when I was LEAVING Zambia a few years ago,and questioned me as to why I was taking the empty cases (Their words were actually not empty CASES but EMPTY BULLETS)back with me. When I told them I re-load the ammo I got a dumbfounded look from the official. He had no idea you could re-load ammo.

What length case would it take to get velocity around the belted H&H or Rugers version of the 375?
I know it would not be commercially viable but that rifle would be an interesting light rifle to have along. I know that the 300 grain bullet would be the one to go with but I have fallen in love with the 375 TSX 270 grain bullet for all around general hunting.

Thanks MacD37, I get you now!

BLASERGUY, I think you'd need the full length 2.94 inches.
Seems CEB Non Cons can do all we need at 270 grains

+1 I just can't see any reason to do this when so many quality bullets are now available in 9,3.
