Every gun is different. There is no #1 ammo for all guns. Just isn't going to happen. Not even for the same make and model of gun. YOU, need to go shoot different rounds and see which one YOU shoot the best. As far as arguing that this hollow point does better than this one; that shouldn't be a major concern. Just about all the name brand ammo from Win to Corbon to Federal to Remi will do what they are suppose to. OR; THEY WON'T. And ALL of them run the risk of NOT doing what they are suppose to. The main reason for HP is 1) Purposely make them slow down and not over penetrate. and 2) Handguns are much slower than a rifle. Therefor you need to try and get a BIGGER hole to make up for damage that it lacks in velocity. Hollow points is a way to cheat and make the bullet bigger.
In my SigSauer P220; the most ACCURATE round for this particular gun is Remington golden sabers 230 grain HP. However; the most accurate with my Springfield Armory 1911A1 circa 1985 is Federal Premium Hydra-Shok. Yet, in my 32acp FEG, Fiocchi HP are the best. And my S&W Model 13-1 357 mag likes 158 grain Hydra-Shoks the best. Every gun is different and every combination of gun and shooter is different. Find the most accurate for you.
On a side note: I really can never understand this, and I've researched it quite a bit. "The Real Mags" brought up something that some people do that make absolutely no sense to me. Why would people "Rotate" or "Stagger" different types of rounds in their magazine? Is it that you don't trust ANY ammo; or maybe even your shooting capabilities. And mixing 3 different manufacturers of the same type of ammo in a magazine makes really no sense. People do it with home defense shot guns also. I.e. 00 buck, then some 4 buck, then a slug, etc... I think there's too much reading Tom Clancy books or watching too many "Shootem Up" movies. The only time this ever made sense was with smaller guns like the 32acp. Because of it's size, some argue that it CAN'T expand enough and FMJ is the way to go to get some penetration. Some also say that when rounds get that small; many magazines don't feed hollow points too well. So some people put a Hollow Point in the chamber, and then the rest of the magazine is FMJ. I can understand this logic. For the others; there doesn't appear to be any logical reason; no reason based on physics or ballistics; and no reason based on defense purposes. It appears to be that the only valid reason is: "Because I want to and I'm allowed to". Sure enough, that is good enough. I was just wondering if anyone reading this actually had a legitimate reason, related to performance, to would justify mixing rounds in a gun. The closest I got to an answer was from someone who does it with shotguns. He said the slug on the 3rd round was in case the bad guy got too far out of reach for the 4 or 00 buck. I told him he better PRAY that he MISSES with the slug shot. That would really be difficult to explain to the police and eventually a court; "I needed the slug because he was about 200 feet away and the buck shot wasn't enough". Yea; that will go over well. Anyway; sorry for the off topic question. Just very curious if there are any PROVEN performance reasons (Other than those mentioned for the small guns) of why people put a mixture of ammo in their weapons. I just don't see it.
