In your country, you drive on the 'wrong' side of the road.
Actually, you do. Apparently it is safer to drive on the left side of the road because people are mainly right-eye dominant.
Anyway, all you have proven throughout this whole topic is that it is a good idea to use grains when measuring bullets. Not once have you demonstrated that it is acceptable, or appropriate, to use grains for pretty much anything else we'd weigh on this forum.
You say 463 grains is 7 NATO bullets, how many NATO bullets do you see on the forum? How many people here do you think have handled a NATO bullet or know its weight in grams/ounces? Perhaps if you said 463 grams was X amount of .X gram BB's, we'd be getting somewhere but then you're just things difficult on purpose and it'd take a lot less time to just convert the measurement to grams.
I've been convinced you're not going to change your mind. May as well lock the topic.
