XD Talk

I use a mix of Cor-Bon DPX and Speer Gold Dot in my EDC Glock but once I'm 100% confident in my XDS I'll likely switch to carrying it, since that was the reason for buying it. With 5+1 I haven't decided if I'll keep to that practice of mixing, my thoughts on it were the DPX is a better round for penetrating something, and doing so while staying in one piece, while the Gold Dot expands better on a clean shot, so mix them and have the best of both worlds. The DPX in 9mm and .40 is longer than my other rounds and I expect that to be the case on the .45, so on the XDS I know it could be a tight fit in there, just wondering if anyone has shot it before I drop $30 on a box and find it doesn't feed reliably.

Corbon DPX 185 gr +p. No problems. Recoil is about the same as wwb. I have issues unloading a live round. It may work better when fully broken in.

You mix ammo in your mag...?

Mixing ammo is a bad idea. Makes the gun much more likely to have a failure and changes the recoil shot per shot. I have to ask Why do this?

I carry the 165gr corbon rounds, recoil is a bit snappier, but the gun liked 'em.

The DPX round has a much better chance of remaining in one piece if it has to penetrate an object to get to the attacker, it has higher speed and more energy delivered, however, it has less overall expansion compared to Gold Dots. So I would prefer Gold Dot if I knew I'd have a direct shot at someone attacking me, but would prefer DPX if there's something between us. If I can get a couple shots off regardless of situation, I'd prefer to be as best prepared as I can be.

I can certainly understand that recoil could differ, but I haven't noticed a perceivable difference in recoil in my other two guns between the DPX and Gold Dot. I shoot 500+ rounds of ball ammo through my guns each month at the range and that certainly has a different recoil profile, as does one gun to the next, so I don't think a change in recoil would matter at all in a pressure situation since I'm already used to a huge variety of recoil behaviors amongst my guns; I worry more about my grip, how quickly I can sight something in after firing and technique.

For the other point though, I shoot a mixed mag like this through my Sig and Glock about twice a month to keep me and the ammo fresh and I've never had a failure. I'm not clear on why there would be "much more likely to have a failure." I'm a novice though so I'm certainly willing to admit I could be missing something that should be obvious. My thoughts are that the bullet is already gone from the cartridge when the slide is forced back, cartridge extracted and next round fed, so the brand, size and shape of the bullet that has already left the gun should have no effect on the round being chambered next. Even if the case lengths were different, if either round feeds reliably on its own, I would not expect mixing them to alter that since the base is going to be the same dimensions regardless and the weapon's extraction and feed mechanisms work the same for each round.

COR-BON 185s are on "The List" so they're GTG. 165s are too light.

I wouldn't mix ammo.

I always buy my defense ammo from you guys.

Just wish you had some bulk deals on 1000~2000 round cases of target ammo.... *hint hint, money in hand ready to buy

Energy has little to do with wounding effect. "Energy dump" is a myth. From the test I've seen the corbon dpx does no better at barrier penetration than gold dots.

We don't do a whole lot of cases. One, because we don't get much ammo in cases, we get boxes loose in large tubs. And two, because we try to price stuff the same low price when we can so cases would pretty much be the same as boxes anyway. Right now ammo is flying on the shelf, so prices are climbing, but we're trying to put out nice sales on our promotional emails.
