I wasn't saying whether shot placement was the biggest or not, it's just my style to say something helps. The amount of help I pretty much never really try to imply because people like to argue what they feel is best, or have learned to be best.
Understandable. I wasn't trying to say caliber is totally meaningless. Any self defense pistol caliber is going to likely require multiple shots to stop an attacker, even when hitting the correct spot. Obviously I am not talking about .50AE or .454 or anything like that.
Basically use the pistol's recoil to do most of the work to get that 'zipper' going, right?
Well, recoil isn't really as huge an issue in typical handgun fighting range(0-5 yards), it can somewhat have an effect, but that is one reason I carry a 9mm, low recoil, high mag capacity. I know guys who can hit targets at 100 yards with a Glock 17, so still "target practice" is a decent thing, but you should mainly practice rapid fire on multiple close range opponents with a handgun.
A still target is an easy target. Or rather, an easier target. At least with my small experience with handgun target practice, well... I need more practice. Then again, if someone says they don't need practice...
I practice a lot, and still feel that it is not enough.
Well the equation looks to be going in the right direction then it seems. I'm just having to work on the part for including the idea of penetration, overpenetration, and the effect that should have on the relative damage it does. And also figuring ideas to get an estimated variance with various barrel lengths, although that one is going to be a bit difficult to get figured out... although generally by just using muzzle velocity as is, it seems to be working just fine.
I can see some license with weapon differences in a game, as far as the barrel length thing goes, there are charts for different calibers in different barrel lengths. Also, with the military and SF teams using more short M4 style weapons over submachine guns now, cartridges are being developed for short barrel weapons. I have seen "M4's" with barrels as short as 7".
