Could I get an explanation? Sig and Mag

[AristoclesGibson]

Define "superior" if you please..

They are very different cartridges, with different case geometry, different case capacity, and they perform very differently except when you restrict the domain to a 125gr projectile in a specific (@ 4 inch) barrel length.

The .357mag can be loaded up or down (pressures and velocities), with light or heavy bullets, and with rounded or flat profiles. It is clearly more "versatile", and is better suited for certain applications (woods carry for black bear defense, etc), but not as good as a high-capacity semi-auto for LE applications.

There is nothing wrong with the 357sig round, except maybe for the price of plinking ammo.. I will stick with 9x19 for personal use in a semi-auto, but that's me. The ability of the 357sig to penetrate hard/intermediate barriers and still achieve acceptable penetration and expansion in soft targets (I.e. carbon-based lifeforms) makes it a terrific choise for LE personnel.

I am aware of what I typed. I am also aware I stated early on I was only curious about the velocity, the entirety of this has been predicated on velocity, ergo the notion of superiority should be clear.

Original Question:

"I am confused, 125 gr. JHP@ 1603 fps versus a 125 gr. JHP @ 1430 fps. Is this a close enough for horseshoes and hand grenades type thing or (more likely) have I missed a lot." I have gone to state clearly why it was what I was really concerned with velocity, cf. below.

"Superior" contextually speaking = higher muzzle velocity. I have attempted to make this clearly the only parameter. I have explained why it is the only parameter I was concerned with, ad nauseum.

At the risk of being sickeningly REDUNDANT, GD link has an example of a round of being fired from what I assume are roughly equivalent barrels and has the Sig with a significantly higher velocity. Evidently the fact is, even when one constrains it to a like projectile (125 gr.) from a like barrel (~4") the .357 magnum case still exceeds the velocity of the Sig by roughly 12.5%, according to the numbers published by BB.

Ok. I guess I was not understanding why you were so concerned with the minutia of something that may or may not have any practical relevence, as "velocity" on its own is simply one small piece of a very large pie.

Actually, more velocity is just more velocity. It doesn't make one superior to the other, it just makes it faster.

My concern ultimately involved why I was getting so vastly different numbers.

Odd that you would overtly have contempt for someone who was confused by two very different observations put up by ammo/bullet producers. I guess the very fact that they would be so silly as to even post such possibly irrelevant minutia as velocity explains it.

Even more confusing is why you would waste the electrons chiming in on a thread that you are neither concerned with nor value.

If the only parameter you have set is velocity then vis-a-vis velocity, it very well does make one superior.

superior = "greater in quantity or amount"

For the record, I wasn't trying to belittle you in any way, and was only trying to help. Carry on.

Sorry, carbo. That is sincere.

I think I stupidly misunderstand on the internet. The more I tell myself to act as a Christian in all manners, the less I do. The last months of worrying about my son's ALL has made me defensive about everything. For Goodness sake here I am on the internet vehemently defending, as if it really matters, a silly curiosity.

I retract the original question; I'm probably too argumentative to hear answers.

God bless

Hey no worries. My apologies to you as well, the way I write sometimes can be kind of dry.

As far as asking questions to gain more info on a subject, the only dumb question is the one not asked. This is a great forum with a lot of nice people who are always willing to help.

Have a great day!
