[QUOTE="wapiti13, post: 81752, member: 2212"] Eaglet, Having shot IHMSA for over 20 years, I have shot so many bullets on steel that I lost count. Handgun bullets vs rifle bullets have similar problems. Long, heavy, slow bullets knock down steel better than light, fast bullets. "Dwell time" which could be defined as the actual time that a bullet has physical contact on the steel is very important. A light, fast bullet might have great energy on steel, but if it just blows up, it will not dependably knock over steel everytime. A heavier, slower, longer bullet maintains contact on the target for a longer time as it expands and pushes. Even full metal jacketed bullets "expand" on steel since they compress and squash down as they push on the target. This dwell time on the target lends itself to more dependable knock down. This is why many silhouette shooters used tough match grade bullets like the old Hornady match bullets. The forerunner to the A Max was a TOUGH bullet that expanded upon contact because of the hollow point, but mushroomed out very slowly and stayed on the target for a long period pushing all of the paper energy onto the steel. Using 162 7mm match bullets, I've peeled paint on targets that looked like I shot the target with a small softball (paint peeled down to the bare steel). This type of contact is not critical on animals because of penetration, but very important on a steel target that must be pushed over off its stand. Hopes this helps clarify steel vs flesh. [/QUOTE]
