There is some confusion and misinformation about 7mm that is common on the internet. Here are a couple of tidbits:

1) There is no minimum caliber law that requires a 7mm rifle for plainsgame in Namibia.

2) A meter is 39.370 inches. A millimeter is .039370 inches. Seven (7) millimeters is .27559 inches.

3) A .270 bullet measuring .277 inches is slightly larger than 7mm, but rifles chambered with the name of "7mm" use bullets measuring .284 inches.

THIS IS THE LAW


Namibia Nature Conservation Ordinance

Restrictions in regard to fire-arms and capturing apparatus

42. (1) No person shall use a revolver, pistol or automatic fire-arm when hunting game or use a
fire-arm of which the bullet has an energy at the muzzle of the barrel which is lower than the following
when hunting the species of game indicated thereunder:

(a) 5400 joules:
Buffalo.

(b) 2700 joules:
Eland
Kudu
Oryx
Wildebeest
Hartebeest
All species of exotic game.

(c) 1350 joules:
Springbok
Duiker:


Here is a quick conversion for the non metric folks.


Minimum energy (Eo - muzzle velocity):
1350 Joule for springbuck, duiker etc. 995 Ft lbs.
2700 Joule for hartebeest, wildebeest, kudu, gemsbuck, eland etc. 1991 Ft lbs.
5400 Joule for buffalo, elephant, rhino etc. 3982 Ft lbs.

Norma ammo in 6.5x55 with a 140 grain Nosler Partition bullet has 3061 Joule at the muzzle.
Very similar with their 156 grain Oryx bullet.

Plenty above the demand of 2700 Joule.

This is good to know, especially for a guy whos only rifle over 7mm is a .338 Lapua. I guess when I go I will just have to be sure that whatever PH I choose is OK with my caliber choice.

I have a like new VC .450 I might part with. I had it built in 2013 and it has served me well. Also have a VC fitted leather trunk case for it along with the plastic case it came with. I'll take 14000 for all of it.

Hi Jody,
I have been looking for ideas on the best way to display my European mounts from Africa. I came across some of your shield work and was wondering if you would be willing to make one for me? If so, please let me know the cost. I like the shield with the two spears that you built for a member years ago. Thanks.
