I'll bet if the FBI see's this they're going to want to change their duty weapons.

Bah! The 45 Colt is an antiquated, big, slow cartidge that's for old cowboys! Practically any newer round is much better... The 9mm for example...

NOT! Once again, big bullets moving 'slow' prove their worth! I'd love to carry a 45 Colt as a BUG on duty to compliment my Colt 1911 45acp that I can't carry either!

Not that impressive - 13" and marginal expansion at 1,100 fps. Here is factory 250 grain Gold Dot at 775 fps 14 inches and insane expansion http://www.shooterslegacy.net/articles/45colt.html

Good looking bullet. I was going to get a .45 LC revolver, but still settled on the .44 Magnum.

DPX... Isn't that one of those new wonder bullets that control it's penetration?!

I thought DPX stood for Deep Penetration Xpanding bullet, or Deep Penetration "X" bullet because of the petals.

I like the .45LC, especially loaded up hot like this one was. Good cartridge IMO.

I wonder how the 225gr Win Silvertips stack up to these?
Not a +p load, but they feel snappy.

Wow. That's the best advertisement for CorBon I've ever seen.

Would these be alright in an older 'Uberti' SAA? Or a Colt 'New Service'?

Both the Winchester 225 Silvertip and Speer 250 Gold Dot are completely safe in any modern revolver as they are both standard pressure and perform better than the DPX which goes to show that there is nothing like big slow bullets in the Colt .45 for self-defense. I believe the 300 to 400 extra fps in the Corbon is a complete waste possibly due to hydrostsatic pressure or the extra speed casuing "premature expansion."

According to Cor-Bon...

The all-copper bullet construction conquers hard barriers like auto glass and steel while still maintaining its integrity. This is an optimum load for Law Enforcement.

- Deep penetration on soft tissue 12-17 inches.
- Easily conquers hard barriers like auto glass and steel.
- Reduced recoil due to lighter-weight projectile.
- Lead-free projectile.
- Environmentally friendly!
Not loaded to SAAMI specifications.
*CERTIFIED: CALIFORNIA LEAD FREE*

* Caliber: 45 Colt Plus P
* Bullet Wt.: 225gr Self-Defense DPX
* Velocity: 1200fps
* Energy: 720ftlbs
* Test Barrel Length: 7.5 Inches
20 rounds per box.

http://www.dakotaammo.net/Self-Defense-DPX/45-Colt-Plus-P-225gr-DPX/DPX45C225-20/200/Product

Or in other words this round is intended for self defense or "law enforcement" use as Cor-Bon says. The bullet is constructed to penetrate less than a hunting round or a standard semi wad cutter load. FBI protocol emphasizes penetration and expansion of 12-14" or so for self defense rounds.

So this load does what it is supposed to do. Penetration is slight for a bullet of that weight and speed. That is intentional and that is due to the construction of the bullet.

In post #11 a link is posted which references the discredited "one shot stop statistics" I would ignore that bit.

Publius1688 - I'm not sure if the 'advertisement for Cor-Bon' comment was intended for me, or if there were any negative connotations intended. Please clarify.

The figures quoted, twice, for the lower velocity load from Speer ... are remarkably similar as those for a 230gr Gold Dot in a .45ACP. This should not surprise anyone, as the weights, velocity and construction (likely) of the bullets are similar. Since the expanded diameters of the tested DPX bullet and the mentioned Speer Gold Dot are close, we are basically talking about the difference between shooting a '.45' and 'a faster .45' caliber handgun.

Precisely. The rounds are constructed to penetrate only so far and expand. In these cases the aim is to limit the penetration of the .45 Colt. A hard cast LSWC round or a FNL round built for hunting can have twice the penetration of these rounds.

JE223---naw, buddy. My comments weren't intended to do anything other that express my admiration for bullet coolness. I'm not savvy enough to debate ballistics.

Publius - thank you for that.

I might look around and see if there are some other good choices to test in this sort of weight/velocity range, just so we can see what the differences between loads might be.

I wonder how much LEO or G-Man use .45 Colt gets these days?


Anyway...these do sound good. Think I may even have a Box of the .45 Colt Winchester Silver Tip tucked away.

I wonder how that DPX bullet would do if you pushed it to 1500-1600 fps--which a Ruger Only 45 Colt load should have no trouble doing.

LEO and G-Man use of the .45LC? None in the latter, right? As for LEO, I knew of several Texas Rangers still carrying it. Not sure if it was duty approved, but they had them off-duty to be sure. After seeing my .45LC, a Gila County, Arizona deputy sherrif almost asked his boss if he could carry a double action in .45LC...

Folks who want deep penetration do NOT want "insane" expansion.

Then you'd probably need to CCW with a 120mm smoothbore ... ? :)

The point was deeper penetration and much greater expansion at 400 fps less than the Corbon - the 250 grain Gold Dot seems to be a much better choice.

I've heard that the Gold Dots are the cat's meow for whitetails too. They say they leave nice big exit wounds when loaded to about 1,000 fps. Anybody here used them for hunting deer?

Any chance you might test the Federal 250 grain .454 with the barnes copper bullets at over 1500 fps?
