"10mm / .40 cal rule"
Gentlemen
Any of you out there ever heard of a "10mm or 40 cal rule" in force on the african continent?
The reason for my question is that I overheard a conversation between some guys who returned from africa, where they were confronted with a minimum caliber policy for the "big five". I did not get all the details, but if any of you out there have heard about it, please let me know.
As I am planning going to Africa in october(country not yet decided), I do not wish to go there "under-gunned". My present "tool" is a CZ550 .375HH. (for buffalo)
Hope you have some info on the subject...

It might be the outfitter's own rule.

Might be the old rule for Kenya DG, but now defunct and does not apply, since there is no DG sport hunting in Kenya anymore.

A .375 H&H or better will do anywhere currently, I do believe.

I don't think those first caliber restrictions considered muzzle energy so a 44-40 could have passed as a legal DG caliber at one time, at least until the PH got a look at it.

You can use a 9.3x74R in Zimbabwe on DG, and in Namibia the rule is based on energy but I don't recall the minimum number offhand.

375 is good everywhere to my knowledge.

Not that these rules are strictly enforced, except perhaps Tanzania.

Russ,
Actually you cannot use the 9.3x64 as it does not and cannot be loaded to meet the energy level, nor does the 9.3x62 unless you handload it, however I have never heard of anyone being filed on for using any caliber in Zimbabwe, its just not an enforced law...The 9.3x64 is the starting legal caliber with factory ammo....

The 375 H&H is legal in all African countries today...

Ray,

Y'sure you've not got those two calibres swapped around?

9.3X64 can be loaded to 375 H&H energy levels. 9.3X62 can't.

Zimbabwe's laws:

THE THIRD SCHEDULE OF THE FIREARMS ACT

(1) A calibre of no less than 9.2 mm in diameter with muzzle energy of < !--color-->5.3 kilojoules< !--color--> is required for < !--color-->elephant, buffalo and hippo.< !--color-->

(2) A calibre of no less than 7 mm in diameter with muzzle energy of no less than 4.3 kilojoules is required for lion, giraffe and eland.

(3) A calibre of no less than 7mm in diameter with muzzle energy of no less than 3 kilojoules is required for crocodile, hyena, kudu, leopard, nyala, sable, waterbuck, wildebeest, zebra, etc.

(4) A calibre of not less than 5.6 mm with muzzle energy of 5O kilojoules is required for bushbuck, bushpig, impala, reedbuck, and warthog.



Joules x 0.7376 = Foot-Pounds



5.3 kilojoules x 1000 = 5300 joules then

5300 joules x .7376 = 3909< !--color--> foot-pounds



Edited to add: Yes, the regs state 9.2 mm in No. 1 above. It's not a typo.

I think Ray meant 9.3x74R in that sentence. Easy to make a typo when the numbers are so close. The 9.3x62 and 9.3x74R don't make the Zimbabwe energy minimum. The 9.3x64 does. (The 9.3x62 in RWS factory loads just barely misses the 5300 joules minimum energy requirement.)



Factory ballistics for all three can be found here:

RWS Prospekt B�chsenpatronen (1134 KB)



It's an Adobe Acrobat file. In German only. The ballistics tables are readable and usable even if you don't read German (I don't). Remember, it's all metric. Velocities are in meters per second. Energy is given in joules. Bullet weights in grams.



Conversion factors:

Meters per second x 3.28088 = feet / sec

Grams x 15.4324 = grains

Joules x .7376 = foot-pounds
