Home Forums Hunting & Shooting Handguns why do new handgun calibers so often fail?

I would like to believe the 5.7 x 28 is "all that", its just hard for me to understand, how a 40 grain vmax at 1700 fps is as effective as even the 9mm 124 grain at 1100fps.

It looks to be a better design than the FN. I am certainly way more inclined to buy one.....eventually.

I get that, but it's not necessarily for the same mission.

My experience on game with the 10mm, .45 ACP and .460 Rowland the the 10mm usually penetrates or deer completely and Rowland usually does but I have never had the ACP pass through. This is using 200gr and 220gr hard cast bullets in 10mm and 200gr and 255g hard cast bullets in both .45s. Our deer in Florida are anywhere from 100 lb does to 200 lb bucks. I have used the 10mm and Rowland on hogs with pass throughs on the 80 lb ones and good penetration to the vitals but no pass throughs on the 200 lb boars. Never tried the ACP on them. YMMV

That's valuable data.

FreeMe, I actually am pretty convinced that the upper potential of the 10mm is probably superior to the upper potential of the .45 ACP all things being equal (barrel length, etc.).

Is your purpose defense against large bears? If so, and you want an auto pistol, then 10mm is probably your best bet, with the most appropriate loads. I was simply saying that, with the best loads possible, the .45 is not much inferior, thus bringing into question the necessity for the 10mms introduction as a sporting round, when .45 ACP is already well established. Necessity, of course, is a subjective matter.

PS As a general issue law enforcement round, it was ridiculous, which is now generally agreed upon.

I shot one 250 or so pound boar with a 45ACP, that was still breathing after I hit him with a 308. I shot him with the 45 in the back of the head from 1-2 feet away with a 230 grain gold dot from a Kimber commander length gun, the pig quit moving very shortly thereafter however as far as I could tell the bullet did not go out the bottom of his head. The gun was near horizontal, the pig was laying on its side, and I was squatted down next to it.

Yep. I agree with all of that. For the record, I would have been happier if we could have seen the 45 Super as a factory option. Yeah, I know there is at least one gun that everybody says is safe to use 45 Super in the way it comes to your heart's content, but I want to see the gun actually billed as a Super by the factory....and have it fit my hand. It's not too much to ask, right?

I'm actually not yet fielding an auto in 10mm. I do like the Match Champion 10mm though. Six shots of major power in a medium frame revolver that I am extremely familiar with is hard to dislike.

In my experience the 230 XTP penetrates substantially more than the 230 grain Gold Dot. The 45 ACP +P rounds give up very little to a 10mm in my experience when the best bullets are used in each.

jwp...what velocity are you getting out of a +P 230?

This response doesn’t seem called for. He asked a reasonable question based on your previous post.

975 to 1000 FPS depending on load and bullet

The 185 grain XTP penetrates very well ar 1200 FPS and is of tougher construction than the 230 grain XTP. The 185 XTP doesnt open as wide as the 230 XTP does

Shhh! Don't tell anybody....(I've been carrying a 1911 with Underwood 255gr CFN too.)

If someone came up with a 9mm Creedmoor, it would sell like hotcakes!

Because they suck.

The advantage to the 5.7X28 is that it is a pistol/subgun round that can penetrate soft armor. Good luck marketing that to civilians without an onslaught of media coverage demanding it be banned.

Another advantage is the higher BC bullets along with speed making it a flat shooter to the 100 and 150yd line. But considering the fact that most people can barely hit the A Zone at 25yds, it kinda makes that advantage moot.

The round really can't be reloaded to potential, and that means you have to buy factory. And it ain't cheap.

You also have to build a gun around the cartridge. This has made it a one trick pony until Ruger stepped into the ring. Who knows where things will go from here.

This is to say that the 5.7 isn't a bad cartridge by any means. Just not as marketable for Joe Schit "need a house gun."

Look for dealers that sell 50 round boxes of what is commonly referred to as "duty" or "LE" and you often can find ammo for ~50 cents a round.

Sample of one, but the 'warm' 185 tac-x that Gunner500 had on hand did a number on the hog it connected with.
I can't directly compare the 10mm on hog because of shot placement. That 185 was a head shot.
