Are you sure you aren't talking about my S&W 1006?Trying to convince 10mm fans that their G20's aren't the greatest guns ever that shoot the best cartridge ever made is futile. In their minds it has 41 magnum power with 9mm recoil and 6mm ppc rifle accuracy
Yeah and trying to convince people that their 380 with modern ammo is just as effective as a 10 or 45 because they are faster back on target is equally futile. Honestly, how many more rounds does anyone think they can get off in your average gunfight?
To wally: i guess I should have stated " using the same load". Thought common sense would take care of that. I have a g20 and a g21. I also have a DW CBOB in 10 & 45. Using like loads ( or as close that is practical), there is no appreciable difference
My 10mm kimber 1911 is the same size as my other 1911 models.The guns are few and all of them pretty enormous.
The 10mm is nearly a dead letter now. The guns are few * * * There are very few choices; you can get a Glock or a 1911, or choose from a smattering of oddball makers. * * *
More power is not "the best" unless you need itHowever, why go 40 and compromise between 9 and 45, when you can have 10mm and the best of power and capacity.
Potatohead said:Uhhh...capacity.
40 S&W is based on a hundred plus year old law enforcement ballistic model.
1. I did misstate the formula for energy; I stated mass x velocity squared, its actually 1/2 mass x velocity squared.
You are still incorrect. Here is a hint Energy = Mass multiplied by the speed of light squared is not how energy is calculated but an equivalency. How Kinetic Energy is calculated is what you are attempting to describe.
3.10mm doesn't recoil anymore than a 45, and you seldom hear people complain about the recoil of the 45. Everybody should shoot the caliber/pistol combo that allows them to put as many of the most effective bullets that they can safely do so.
Full power 10mm ammunition creates considerably more recoil than .45acp.
4. A lot of the people that weigh in on the 10mm, are doing so based on heresy and internet rumor with no real time actually shooting them.
I am not one of those people.
Looking at Underwood's loadings for 155gr:
.40S&W - Muzzle Velocity: 1300 fps & Muzzle Energy: 582 ft. lbs
10mm - Muzzle Velocity: 1500 fps & Muzzle Energy: 775 ft. lbs.
Seems like a significant difference.
It only seems significant because bigger numbers appear impressive. When shooting human beings that extra 193 foot-pounds of muzzle energy is about as significant to outcome as the difference between dropping a 582 pound boulder or a 775 pound boulder on a persons chest.
...assuming that there is nothing other than air between the dropper of the boulder and the person's chest.
