After doing some thinking on the topic of microstamped bullets I've changed my opinion. I was vehemently opposed and couldn't imagine this would catch on. I was wrong on both accounts. I now think it is a great idea and I think it will do exceptionally well and will be accepted by the majority of shooters.
What I realized was the company pushing this (see Sebastian's post) was trying to use a government mandate instead of the free market. Which, of course, is nearly always a recipe for disaster. They will get much greater market acceptance with a free market approach.
I think that there are a lot of people that would pay another penny per bullet for something like "Mist Maker" engraved on their Speer TNT bullets. I'd pay an extra $0.02 per bullet so I could load up 9mm jacketed hollow points inscribed with "Please Don't Rape" for the women in my life to carry. In my case even at an extra $0.05 per bullet I'd order 1000 Berger .308 caliber 210 Grain Match VLD's engraved with Μολὼν λαβέ.
