Careful... you're going to upset our resident 10mm freak by reminding him of that.agilent_one said:Hey 10mm guys:
The .45-08:
250grs @ 1200fps
230grs @ 1250fps
200grs @ 1400fps.
The nice thing is that any reliable 45acp w/ a bigger recoil spring and shock-buff can handle these.
Seems to blow the 10mm out of the water, doesn't it?
Rick said:Second, while I still don't own a .45 ACP and probably never will, those who do can buy a relatively inexpensive spring, buffer, and a handful of cases and have a .45 ACP that is far more ahead of 350 Mag's 10mm than his 10mm is ahead of normal .45 ACP loads. Run .45 caliber 200 grain bullets at 1450 fps through that ballistics calculator against any of 350 Mag's beloved Double Tap loads. No barrel chambered for a wildcat required, just a spring and buffer swap, and enough prepped cases to have what you hope you never need.
And worst of all, 350 Mag can stuff powder in his 10mm cases until he blows up his gun, and he'll never get that performance that .45 ACP owners can have. Expansion ratio just isn't on his side.
The 10mm is a very good caliber. There's absolutely nothing wrong with it, and it is a very good choice in an autoloader for an ATC pistol. But to seize on that caliber and proclaim the .45 and its' performance to be antiquated and a "joke" is just the sign of a newby.
IM_Lugger said:.45-08 is NOT .45ACP! I wonder how many of those rounds 1911 (or any other .45) would take bafore falling apart...
What's the pressure of the .45-08 anyways? .45ACP +P is about 22,000 PSI
agilent_one said:At the velocities stated, QuickLoad says ~40000psig.
Well, the measurebating seems to have subsided - perhaps the numbers were too close between the two.python357 said:You guys still going at it ??![]()
Rick said:Of course, he finds it "normal" to replace the entire barrel in a Glock Model 20 so you can safely shoot those hot loads in it without risking a ka-boom, but it ain't "normal" to simply use a different recoil spring and buffer in a .45.
And Double Tap ammunition isn't "normal" ammunition either - but he doesn't have a problem with that either. Even though he can't get any to use killing paper targets in the first place...
And you're right. If it is some kind of a "race", .45 ACP owners can simply put in a different spring and shock buffer and get numbers that pretty clearly exceed whatever the 10mm can bring to the table. The 10mm, on the other hand, is what it is, and blowing it up trying to get the same numbers out of it you can get with a .45 ACP simply with a different spring, buffer, and prepped brass won't change that any.
350 Mag said:He was asking about .357 or 10mm....NOT .45 ACP??![]()
Normal .45 ACP (not .45 Super, .451 Detonics, 45-08 Armco, or 460 Rowland) is NOT an adequate round to dispatch a Black Bear. It may or may not do the job but lacks penetration needed to be considered an adequate bear gun.
.45 ACP belongs in a museum, old cartridge, past its prime and quite easily a joke when compared to 10mm Auto which can run circles around the .45 ACP in any department...Faster, Flatter shooting, more accurate, more energy, more capacity, better penetration etc etc etc.
more capacity.....PROVEN all beit not much advantage in Canada(1-2 rounds) so TRUE it does on average hold more.
agilent_one said:On average, this is true. But there are several manufacturers of "hi-cap" .45's (or 45-08's) - for that matter.
Rick said:Oddly enough... if all I could legally do was shoot targets at the range like most folks, I'd probably shoot either .22 rimfire or .38 Spl, 9mm, something like that. It doesn't take much energy for a bullet to go through a piece of paper, and cheaper ammunition means more shooting. .22 rimfires will kill pieces of paper just as well as some LoudenBoomer cartridge loaded to the max with rhino rollers.
Of course, who knows... I suppose you could always be charged by a bear while at the range killing paper...
350 Mag said:My original post...
10mm compared to 45 ACP...
faster.......PROVEN
Flatter shooting....PROVEN
More accurate........ not for bullseye ...combat accuracy toss-up
more energy.....PROVEN
more capacity.....PROVEN all beit not much advantage in Canada(1-2 rounds) so TRUE it does on average hold more.
better penetration....PROVEN.
350 Mag said:Correct you are...
I own a S&W 1006 10mm and a 4506-1 45 ACP.
Both basically the same but the 10mm holds 9 rounds the 45 ACP 8.
Most single stack 10mm hold 1-2 rounds more than single stack 45's. Small but visible advantage.
My 10mm Witness WOULD hold 15+1 but sadly it is limited to 10.
slap: I have never seen any "book data" printed on the 45-08 so not sure if anyone has EVER done the loads with pressure testing equipment or not...
You definitely have to pick a SAFE firearm
Gatehouse said:Holy crap...Reloading 101..brass is weak, modern guns are not.
Make brass stronger (like 45-08) and the modern gun can take more pressure. Brass will fail LONG before steel...
make your gun digest a steady diet of strong loads, it wil fail sooner than if you gave it weak loads. Same as for ANY handgun, ANY cartridge..
IF OUR GUN IS NOT UP TO THE TASK OF HIGHER PRESSURE LOADS- don't use them...Just liek if you own a Garand and think about using top end 30-06 loads- DON'T DO IT!!!
If you feel your 45ACp is not up to the task of 45-08, dont do it!!
Before modern pressure testing gear, most data in manuals was worked up by case head expansion testing and "good guesses" It is remarkable to see that much of that data is still in line with modern data, done wiht pressure gear.
I trust that Gunnar (Armco 45-08) knows more than a litle bit about handguns.
Rick started handloading when I was in Boy Scouts.
I started handloading about 15 years before 350 mag ever owned a handgun...
None of us are going to blow up a gun.![]()
IN practical use, a 10mm is just as good a cartridge as a modern, high pressure loaded 45ACP. Period.No more, no less.

Gatehouse said:It is also proven thst a 22-250 is flatter shooting and has more energy than any of the old "buffalo" cartridges. Which one do you want in your hand when a bear charges? A 22-250 or a 45-90?![]()
350 Mag said:your comparing a 22 caliber vs a 45?
acrashb said:No, he is using your criteria to compare 22-250 to 45-90, demonstrating that your criteria are either inadequate or incomplete.
