    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 where the confusion stems from.




    Here is a quick conversion for the non metric folks.

    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.
