Ballistic gelatin test results : .327 Magnum Speer 115gr Gold Dot JHP

[Jim March]

It generates pressures in the 40,000 psi range, and is almost the ballistic equivalent of the .30 M1 Carbine. This is not what you want in an ultra-light S&W J-frame platform.

Agreed. It makes all kinds of sense in a 26oz Ruger SP101, and would be reasonable in the 20-21oz range (steel S&W snub).

 

[Schmidlin]

Hey if they want something in a S&W give it to them, maybe they will stop complaining.

 

[XDShooter07]

The round is described as having 20% less recoil than a .357. I understand recoil is completely objective but I imagine that gets us pretty close to the recoil of .38+P. With the round offering better ballistic performance than .38+P with similar recoil I fail to see what makes this an unsuitable round for a lightweight snub.

 

[Vicious-Peanut]

This round looks extremely promising. I admit that at first I was leary of it since it was only .31 caliber and all, but it expands nicely and penetrates wonderfully. It would be very, very nice in an SP101 and especially a levergun.

 

[Drgong]

unless I am somehow fall in love with another gun before then, I am saving up my money for a SP101 in this .327... will let the board know how it shoots

The more I read about it, the more of a fan I become.

With the round offering better ballistic performance than .38+P

I'm confused. How is this better than the old-standard 158gr +P FBI load?

 

[RyanM]

I'm not a ballistician but how can it have a "recovered" weight greater than it's starting weight?

They could also just weigh more than the weight that's on the box. I've pulled a bunch of "36 grain" .22s, which were actually 38 to 40 grains.

 

[Shade00]

I never said I wanted an Airweight. I would love to have it in a stainless steel hammerless S&W.

 

[XDShooter07]

I'm confused. How is this better than the old-standard 158gr +P FBI load?

Here are some velocity and energy numbers from the manufactures' websites for some of the most popular .38+P rounds and the only 3 .327 Mag rounds currently available. The only .327 Mag round that doesn't beat out all the other numbers is the Federal Hydrashock; the Buffalo Bore .38+P beats it out in muzzle energy; I imagine that's because it's an 85 grain bullet, and from what I've read Buffalo Bore loads their ammo very hot, even for +P. The other two .327 rounds beat out all of the ammunition listed below "in the numbers" (the Buffalo Bore comes close though). I have to wonder what the numbers would be on a .327 Mag loaded by Buffalo Bore??? Please bear in mind I'm not implying that the .327 is an all around better round. I said that it had similar recoil and better "ballistics." None of this is from first hand experience. The recoil is from what those have used it thus far have reported and the ballistics are numbers reported from the manufactures'. The numbers are the facts of the "ballistics" and they speak for themselves.

From what it looks like if you want to go with a .327 Mag round, right now the one to go with would be the Speer, unless you want a solid tip.

If anybody wants any other rounds added to this list let me know and I'll edit it in.

Summer Concealed Carry

I too, would like to see a 6 shot, J-framed Smith in this caliber but I think I'd really like to see a smaller more concealable 5 shot revolver in this new round. I own a J-frame .357 now and while very concealable for me in medium to heavy clothing it becomes a bit harder if not impossable in light summer wear, so in summer months I opt for smaller caliber guns like the .380 Ruger LPC. LM

Living in South Florida. I require a weapon that is easy to conceal beneath a hawaiian shirt and cargo shorts. I have carried S&W J-frames for nearly 20 years in a DeSantis Cozy Partner IWB holster dressed just this way and never had a problem with concealment and I don't feel a personal need for a skinnier gun. I for one would appreciate the extra round a .327 would allow. Personally, I would like to see a S&W J-frame Centennial in .327, stainless steel with a 3" magna-ported barrel, black finish and Crimson Trace LaserGrips. With a good gun belt and IWB holster, I don't see the slight extra weight of the stainless steel as an impediment. S&W, are you listening?

 

[Old School]

The 9mm outperforms the 38 special in a revolver. It is cheap and readily available and allows the use of moon clips for fast reloads. I am not sure this round offers anything substantial over a good 9mm revolver.

 

[9x19sig]

What does it offer? Higher performance, higher capacity, lower recoil.... I guess that's really not reason enough to come out with this new cartridge though.

I really bet somewhere along the lines electricity was shunned because it had no real advantage over candles. And automobiles had no real advantages over horse drawn carriages.

Seriously though .327 does have advantages, check out performance of 9mm out of a revolver, its not that stellar.

The numbers are the facts of the "ballistics" and they speak for themselves.

Are you talking about terminal ballistics, or just general bullet flight ballistics? Because if we're talking terminal effects of the bullets when used for self-defense, I don't put a lot of faith in the numbers. I guess I'm what people like to call a "jello junkie" and I base my handgun ammunition choices on how they perform versus the FBI minimum penetration standards in ballistic gelatin.

If a bullet can penetrate at least 12" and still expand, then I find that it's "good enough" for carry, and I don't worry much about the numbers past that. More penetration is always better though, to me. I don't know if a .327 of any size is going to offer that over a 158gr .38 special.

I will freely admit that the gain of a sixth round in the same size package is a definite advantage, it's 20% more firepower. However, if I was concerned about capacity, I wouldn't be carrying a snubnose at all, I'd be packing a G26 with 11rds on tap and another 10rds a simple magazine swap away.

General bullet flight.

brassfetchers tests show 11-12 inches of penetration with good expansion from the FBI load and 14.9 inches of penetration with the .327 gold dot with good expansion. Are you seeing different tests of the FBI load that I haven't. I don't think the .38 is under-gunning at all. I own a 340 and after feeling the difference between +p and .357 I will be sticking with +p. But from these tests the .327 looks like it has some serious potential to outperform the +p.

For the sake of not making you think I'm attacking all your posts. Ditto. I might carry a G19 mag as a reload though.

S&W still makes stainless steel J-frames with three-inch barrels -- here's the 3" Model 60:

http://www.smith-wesson.com/webapp/...d=10001&productId=14755&langId=-1&isFirearm=Y

Weighs 24 oz, which is 3 oz less than a comparable SP101. That's the gun I want chambered as a six-shooter in .327 Fed. Mag. You would have a handy little trail gun with 6 rounds, good power, fully adjustable sights (unlike the Ruger) and a decent barrel length, which is more appropriate for a hot cartridge like the .327 than a 2" snub barrel anyway. Keep the good performance, like those Gold Dots JE223 tested from the 3" Ruger barrel. Mean!

Plus you can load the gun with pipsqueak .32 S&W Longs (or cowboy/downloaded .32 H&Rs) for soup can population control and general fun.

That'd be a sweet revolver.
