Except price
That's what I was told tonight after being handed a $22 box of 10mm.
Any responses or comments? Lol

Put a 45 ACP in a 10mm and see what happens.

My brother was a cop for 2 yrs and he was out shooting with his captain and he accidentally grabbed his 40 S&W instead of his 45ACP,it did shoot but not eject right. In fact he fired 3 or 4 shots thru his Kimber before his realized it was an ammo problem and not the gun.
That being said, I think the 45 is easier to shoot than the 40. I think both are deadly rounds and you might get a little more range from the 40, if you shoot either a lot you can be deadly from any range.

Lol don't put a 10 mm in a 45

What moron told you that? I hope you straightened him out.

Just because you buy your ammo at doesn't mean you should listen to their idiot clerks.

No difference except price!! Lol except the fact the 10mm is more powerful than 45acp( 10mm has more energy than even a 357 mag) 10mm has a smaller bullet diameter.. I dunno maybe the 10mm and 45acp come in a same colored box. Lol

Not from Walmart. I'm hoping he was just busting my balls sometimes it's hard to tell if he's trying to force his opinion or if he's serious. It sure got me going though. I walked away and couldn't help but turn to my buddy and say. "He's so full of sh!t it's simple physics, heavier bullet higher velocity means more punch "

I am guessing that you are saying they are the same ballistically. I know that you know they are not the same cartridge and not interchangeable.

My Hodgdon reloading manual shows max speed for a 200 grain bullet in 10mm at 1172 using longshot powder. The max for .45 with a 200 grain bullet is 1013 again with long shot. The max my book shows for the 10 mm is a 200 grain bullet. The .45 data goes up to 230 grains. I am sure people use heavier bullets for the 10 than 200. But I often load 255 grain lead bullets in my 45. The pressure levels are much much higher in the 10mm though.

Hmm. I have changed my mind sitting here typing this. I have heard a lot of people say the 10 is more powerful. I am thinking maybe not. Going from a 45 down to a 40 to pick up 159 fps. I think I will stick with my .45s. A 255 grain bullet is nothing to laugh about.

Now you got me wanting to see more load data to compare the two. I know I've seen 265 grain bullets for the 10mm and if I remember they were still moving over 1000 fps. The max I've seen out of the 10mm was in the 700 fpe range about 200 fpe short of a .44 mag.
