[QUOTE="HarryN, post: 936021, member: 69773"] I completely admit to being a beginner, but here are my thoughts on the subject: a) The US military has been under pressure to move away from lead (and DU) bullets, especially for ones carried by field solders (as opposed to artillery). There are major programs ongoing to move toward lead-free bullets and a lot of development money is being spent to make this happen. Of course, their needs are somewhat different than those of a "hunting" bullet, but they consume so many rounds compared to the civilian population, that lead-free / copper or brass machined bullets could come to dominate production volume over the next 20 years. I am not sure if it maters, but machining the bullets offers the potential of bringing the supply line closer to a battle zone. b) Law enforcement, perhaps the second largest consumer, will follow the lead of the military. c) Machined bullets (with drive bands) have been used in artillery and tanks for a long time. They are a well proven method of performance enhancement, friction reduction, and improved gas seal. (your car has used the concept for years - piston rings) Of course, they have the option of using tungsten / DU rounds and we don't, so our options are smaller. d) Machining a bullet "might" offer the "potential" of tuning a bullet further than could be achieved with a cast / swaged bullet manufacturing approach. I don't claim expertise in this area, but you can sort of see this in the CEB product line, which has products clearly focused on different applications, lower FPS expansion potentials, and "thick" vs. "thin" skin animal products. e) The other area that the military is interested in is reducing the weight of ammo carried by soldiers. To this end, they have been testing rounds even smaller than the 5.56 NATO to the even smaller 5.7x28 and plastic cases to replace brass. Reloading is not part of the concept with these products. I don't have a crystal ball, but when the US Army talks (and spends) things happen and directions get set. [/QUOTE]
