Corbon DPX

who makes the best hollow points with the best expansion?

 

Impossible question to answer..

 

Now there are good ammo, but may vary from gun to gun. Best for you to do is see what HP ammo you like, get a bunch of different ones and shoot all of them through your gun and see what you like the best.

 

Again, what works in my gun and what I like, may not work well for you or your gun.

Some people say Winchester Ranger SXT

I really like the Hornady Critical Defense line of ammo.

so double tap any good? are they exagerated? looking for the most expasion...

Super-Vel did........

Lots of good reading here ---> http://ammo.ar15.com/project/Self_Defense_Ammo_FAQ/index.htm

Ammo is really only good At one thing at a time. Max expansion will get hung up in clothing, max penetration goes through the BG and the next wall...even with ballistics gel the answer is not cut and dried because the temporary vs permanent wound cavities both count and the depth of the large cavity matters.

 

Just use a shotgun, lol

lol! shocker... or some lead cast 10mmm like these...

In the 9mm format, many swear by Hornady Critical Defense. I've never used them and had a difficult time justifying their expense. Do some searches, readings and research. Many of those claims for the HCD have not been publicly substantiated, from what I've read. I don't want to get into a pissing contest with anyone about this particular ammo. Do your own research and make an educated decision. The only HP's that I current own are Remington Golden Saber 147-grain JHP's that I got while on-sale from MidwayUSA for $15.99 per box. I purchased several boxes and ran a few through my Beretta 92A1 to make sure the functioned fine. They worked great and were accurate well past an expected range for HD/SD.

 

I read some very good reviews about these that actually included data and specs. If I can find the links, I'll post them.

Speer Gold Dots. Carried by more PD's than any other round (just made that up - but I bet it's close to the truth)
