9mm 147gr

[belus]

A 147gr 9mm round ends up being sub-sonic out of a 4" barrel. I think velocities are typically quoted in the mid 900's. Does that make them any quieter without a suppressor?

I've accumulated three 9mm's now and I want to build a stash of ammunition for them. Most of the stuff I can find at local shops and ranges is either 115 or 124gr, so I haven't yet tried these out myself. Of those two though, I prefer the heavier weight because it seems to have a longer, less sharp, recoil impulse which is easier to recover from.

I'm also under the impression that the slower round will put less wear and tear on the gun.

Any advice is greatly appreciated, thank you.

I haven't shot 115/124/147 side by side enough and paid attention to tell you w/o a suppressor if one or the other is quieter. I wouldn't think it would be enough to matter; it's still going to be pretty loud unsuppressed. I have heard that out of a 16"+ barrel, it's not that bad, although I haven't tested it yet myself. An acquaintance of mine has a SBR'd RRA 9mm carbine + suppressor, and he says it's like a .22 or quieter going off.

I don't know about the wear and tear considerations. I thought (please correct my ignorance) that the higher bullet weight meant a somewhat lower pressure round?

Not by any degee that makes a difference if any.

I agree more of a shove than a slap.

I'm also under the impression that the slower round will put less wear and tear on the gun.


I don't think so.

I find the 147 grain more accurate in my Taurus and S&W 9s. It travels about the same velocity as a Federal 147 +P+ 38 without +P pressures.

I just ordered a CZ 75B so I'm ordering some of the above

I've got some of R.A.R.'s .45 ACP/Auto RIm & .357 Mag ammo as well
as some custom spec. orders - reliable & accurate.

Order a small amount at first. CZs occasionally hold open prematurely with 147 gr. loads that are too long/long ogive.

Cz 75

My CZ-75 was reliable with the 147 grain loads, but would not shoot to the point of aim of the 115 grain loads.

I do not think these loads offer you anything over the 115 and 124 grain loads.

I'm not a big believer in subsonic 9mm ammo. Neither is the FBI a few years back they issued 147 grain hydrashock to their agents and found in real life that round did not expand at all and pretty much over penetrated. They have since switched to the 124 grain hydrashock which expands from .355 to approxamently .59 on a par with similar weight 9mm premium cartridges.In tests frangible bullets have proven to be most deadly unless you believe a wound channel of 2.1" x 5" is harmless. http://www.goldenloki.com/ammo/gel/9mm/gel9.htm

The 147gr Winchester Ranger Bonded is the recently selected 9mm load for the FBI.

FBI AWARDS SECOND AMMUNITION CONTRACT TO WINCHESTER

Winchester Ammunition
2/7/2008

Winchester® Ammunition is proud to announce that it recently was awarded a second contract to service the Federal Bureau of Investigation (FBI). In addition to its contract with the FBI to supply 40 Smith & Wesson loads, Winchester Ammunition will also supply 9mm Luger ammunition.

The new 9mm Luger contract is worth a maximum of $54 million, and the two contracts combined will be worth a maximum of $108 million over five years — the largest ammunition contracts in the history of federal law enforcement.

Winchester Ammunition will produce 9mm bonded service ammunition, training ammunition, reduced lead training ammunition and frangible ammunition for the FBI for one base year, with four, one-year renewal options.

“With the latest advancement in our ammunition lines, the 9mm bonded design combines all the best-known technology features into one bullet to deliver the superior performance required by the FBI,” said Dick Hammett, president, Winchester Ammunition. “It’s sure to be a success with our nation’s law enforcement.”

Winchester’s 9mm service ammunition utilizes a 147-grain, bonded hollow point bullet and was selected over all other rounds tested. The FBI evaluates the terminal ballistics of each round by shooting a specific test protocol through various barriers such as heavy cloth, wallboard, plywood, steel and auto glass into ballistic gelatin.

In addition to the FBI, the contract impacts many agencies both inside and outside the Department of Justice, including the Drug Enforcement Administration, Bureau of Alcohol, Tobacco, Firearms and Explosives and U.S. Marshal Service.

“On behalf of Winchester, we are extremely proud that our nation’s premier law enforcement agency has elected to use Winchester Ammunition in its mission of protecting and defending the United States,” said Hammett.

My department issued the 127 +P+ Winchester Ranger T until a couple years ago. We switched to the 147gr Ranger T loading. I like the 147gr load better there's less muzzle blast and on night fires there's no noticeable muzzle flash, penetrates cars as well as the 127 bullets, etc. There's been no differences in OIS's.

One quality attracting me to the 146gr loads, aside from their expected softer shooting, is the ability to carry the equivalent of 15+ rounds of .38 Spl +P. On paper the same weight bullet in a standard pressure 9mm edges out at maybe 50fps faster than a +P 38 from the same length barrel.

In the event of a shooting for self defense I'd like to retain as much of my hearing as possible. It's mainly for this reason I wouldn't load a revolver with .357 in my home, and one of the reasons I'm attracted to the sub 1290fps velocity of heavier 9mms. Of course this is all qualified by choosing an effective and reliable to round to begin with.

Without the first hand experience of killing something with a handgun (coyote, javelina, etc.) I've formed most of my opinions from Stephen Camp's articles.

the original 147gr loading was designed to be sub-sonic to work better with suppessed weapons. it isn't noticably more quiet in an unsuppressed weapon...at least out of side-by-side sig 226s.

after the FBI Miami Shootout, the FBI went with the 147gr slug because they thought penetration was the answer to their needs...NOT. many LE departments went with the sub-sonic 147gr based on their adoption. luckely clearer heads prevailed with the introduction of the 127gr range and the 124gr GD.

i wil admitt that the 147gr sub-sonic was the most accurate factory loading i've ever shot in my Sig, amost as good as a 135gr handload...it has to do with the lenght of the bearing surface
