[QUOTE="Mysticplayer, post: 28290, member: 8947"] I will throw my two cents into this ring. For me and LR target shooting, I want the bullet with the highest BC number with the lightest weight in a given calibre. This means that I would lean towards a solid copper or similar type bullet. This material would also have to be very durable so that it could withstand the high RPM's when travelling at least 2800fps, preferably 3000fps. If I was trying to "kill" something, then I would want high BC but allow very high bullet weight and extremely tough jacket material. This is best shown by the nasty stuff that comes out the front of an A-10's cannon. The use of depleted uranium is to have a very dense and heavy core to aid in penetration of hardened targets. So the question that Max poses has two correct answers depending on the bullet's use. The perfect 1000m BR bullet would be a 6mm bullet weighing 85 to 95gr that was over 1.5" with a BC exceeding 0.85. The material would withstand being spun in a 1in6 twist at 3000fps. Now that would be technology... For LR hunting out to 1500yds, it would be a 6.5mm bullet over 2" long weighing 120 to 140gr with a BC also exceeding 0.8. Since we are dreaming, why not BC at 1.0 with a SD over .4. Twist rate would be very fast for sure. That way recoil would be very tolerable, throat life excellent, bullet almost not slow down, SD amazing for excellent ongame performance. This dreaming could extend to all calibres. Jerry [/QUOTE]
