10mm Vs .357

Ultimate Velocity 10mm?

Howdo folks, the Centimeter/10mm can safely run a 135gn Hp to well over 1800fps with a book load using 800X from a five inch 1911! 1000fpe clean and simple.
 
10mm vs. .357...which can you handle better, i.e, recoil....remember shot placement..shot placement...shot placement...double taps...shot placement......etc, etc. :D
 
Do you really want to use a .454 for self defence? Can you say "just buy a shotty"? Honestly though, the recoil, cost, size, and overpenetration of that weapon tend to lend it to hunting purposes. As well as being able to tell your friends that my handgun really is more powerful than yours.
 
That doesn't really tell you anymore than factory published data.

In the scenario you describe, you only know what the round will do in the particular weapons in which you tested it on the day you tested it.

1. There can be a great deal of variety between difference weapons of the same make and model. There's no guarantee because your load yield x fps out of your weapon that it would deliver the same velocity out of someone elses.

2. Three months later, you could take the same ammo and get a different reading.

3. A year later, you can load the same ammo with a different lot of powder and/or bullets and get a completely different reading.

4. You could finally get your chrono calibrated and discover everything you done was wrong.

In other words, factory data--particularly when discussing loads by manufacturers like DT and BB--are plenty good for discussion. The fact is ammo performance is not set in stone--there can (and is) be a great deal of variation of what is, at least nominally, the same load.

Juliett... I find this an interesting post. Would not all these same variables apply to factory data as well? I would also point out and ask why it is that so often factory data is found to be incorrect when used in real life situations. Many of us have read many reviews in magazines, online, and such that point out different ballistics than what is published by a manufacturer. My point is that I can sit down and handload with precision what a manufacturer does in bulk. I have no financial gain to make by boosting my velocities and performance, such as ammunition manufacturers do. My point is that by sitting down and handloading, you can match oranges to oranges, bullet weight to bullet weight, use the same chrono, everything. Not eveyone has access to a climate controlled indoor range.. I do. :) Do you honestly believe the manufacturer sits down and does all their loading data on the same day with the same chrono and the same weather conditions? I seriously doubt it. That data has been around and changed only when a load changes. Then they just rechrono the new load.

Some of us prefer to see with our own eyes.. not trust the salesman that what he says is true.
