Is this a decent home defense round? The guy at the store told me lighter bullets are safer because they reduce the risk of overpenetration, so I bought the lightest ones they had at the store. It's in a 4" Ruger GP100.

I realize now that I should have done more research before purchasing, but I was already at the store/range. Now I see I probably should have gone with a .38 special load since .357 inside is going to be LOUD and bright, but this will have to do for now.

I bought a box of 20 and shot 14 rounds at the range with no problems at all. Wish I could have shot more but it was like $20 a box, I just wanted to make sure it worked OK in the gun first. I have 6 rounds left over - I figure if 6 rounds of .357 magnum isn't enough, I'm dead anyway :o

It's a good round. I do recommend bench-shooting a cylinderful as you may find it's less accurate that some other choices in your gun. Generally the lighter the round the less accurate in 357. Once you get past 130gr things seem to improve.

A lot of it has to do with "contact patch area": how much bullet gets to rub on the barrel on the way out. The Cor-Bon 125gr all-copper DPX is getting a decent rep for accuracy, possibly in part because copper's reduced density gives it a contact patch more like a 135-140gr.

But I really doubt it'll matter much at across-the-room ranges. And a 110gr doing over 1,500fps is no joke.

Thanks, nice to hear it's a good round. Like you said, I'm not too concerned with accuracy at home defense ranges. This is my first revolver so I'm not very accurate with it yet anyway, not used to that long double action trigger pull. Most of my shots were high and to the left at 7 yards, so I still have to practice a lot with this gun.

The 110 gr. Corbon DPX is .38 Special. I carry it in my S&W 642. I believe you confused that with the .357 round that Corbon makes for .357 mag. That would be the 125 gr. If you have the Ruger GP100...do yourself a favor and get the 125 gr. Corbon DPX.

This is the round I'm talking about: https://dakotaammo.net/shop/product_info.php?cPath=21_34&products_id=44

This is what I got with Corbon loads several years ago. I suppose the current rounds are about the same. My only objection to the 110 grain load was that it shot several inches lower than the other loads at 25 yards. this should make no difference at 0-15 yards. the 125 and 140 grain loads hit very close to the same from the 4" and 6" GPs

CorBon Load Velocity

Yeah, this isn't a DPX round, it's a conventional lead hollowpoint.

At those speeds, *I* wouldn't wanna get hit with it.

I don't know what kind of powder Cor-Bon is using but with a 110gr round there's going to be A LOT of noise and muzzle flash.

[Jim March]

Noise, YEAH (what? :)) but Cor-Bon does use flash-suppressed powder in their combat loads.

Look, the 357 is fundamentally a VERY good cartridge. There's very few "bad" rounds in 357 that don't work well. Same is true of the 45ACP, 45LC, even the 44Spl.

The 38Spl, esp. when fired out a snubbie, you have to be REAL picky with your loads. There's about 9 or so fighting loads for the 38 I would trust my butt to, and a few of them are hotter than I'd want to shoot out of my 17oz snub (the wilder Cor-Bon and Buffalo Bore offerings).

9mm isn't as sensitive but you should put some careful thought into ammo selection.

Drop the power even further, to 22Magnum in a handgun, and the ONLY round I trust is CCI's 30gr, preferrably the "TNT" variant with a Sierra bullet. Or the 32Mag, only ammo even halfway OK right now is the 100gr Georgia Arms load, unless you handload, in which case take a 60gr Gold Dot meant for 32ACP and drive it like a bat outta hell.

Y'all have heard me on these forums get real picky about ammo to run but that's in the milder calibers. Raise the power level, esp. heading into 357 territory, you don't have to be as anal. Winchester White Box 110 JHPs in 357 will "git'r'done" pretty good and I think the Cor-Bon 110s being discussed here are a good jump past that.

I'm a big Corbon fan. I search gunshows for the older 110 .357 loads @ 1350fps. For me at least, Corbons seem to be milder than other brands with the same ballistics.
