357 Mag and buffalo bore ammo

[Deerhunter#1]

Anyone try the 158 grain offereing. Its advertized at 2100 ft second in a 16 inch barrel which puts it at Maximum velocities. Curious to see if anyone has tried it and what results they got.

[Deerhunter#1]

Not one person has tried it!

[gcrank1]

I think that is because many of us are reloaders too. Im too well fixed for components to buy the high priced factory stuff!

[Deerhunter#1]

myself as well. I was just curious as those velocities that I probobly wouldnt be able to achieve with 158 grain ammo so it intrest me to see if it worked well in the handi. I reamed mine and am shooting maxi loads but I just thought it would be good to know that there is something out there if needed for factory ammo that would perform well.

[mechanic]

Because I have more than one 357, I load only moderate loads in 357 cases, and save the hot stuff for the maxi, so I can't confuse them.
 
This seems like a very hot load for a 357, and I would'nt want to try it in at least one of my handguns...

I would like to know what they are using for powder.  I really like LilGun in the 357 Mag.  Check Hodgdons pressure for the 158 gr Hornady bullet, notice it's much lower than H110.  DP

[Vic49]

I don't see any 2100 fps .357 loads where are they listed?

[Vic49]

I still don't see the 2100 fps loads.

[Deerhunter#1]

Vic- go to there site. Click handgun ammo- select 357 magnum-select 19c/20- when it comes up scroll down at the options. The last one is in bold print that gives the information.

My Grandson has had very good luck with the 158 grain.  This year he took a mule deer and a whitetail with two shots. He also destroyed a Large Armadillo with a Quartering shot .At this rate he has 47 more critters to go with  the box of Federal soft  points bought a Walmart for $22.98.Going to be real hard to get him to shoot anything else 

[cudatruck]

2100 fps in a 357 Mag? unholy little zippers batman! has anybody checked these velocities themselves? is this accurate? that is screaming fast. If they can get that what could they do with a 357 Max?

[cudatruck]

checked able ammo they are out of stock but only list this as 1475 fps?

[quickdtoo]

I still don't see the 2100 fps loads.

Heavy 357 Magnum Ammo - 158 gr. J.H.C. (1,475fps/M.E. 763 ft. lbs.) - 20 Round Box
 
Our 357 mag. ammo adds more power than ever before to the 357 mag. This ammo is safe to shoot in ANY all steel 357 revolver - this includes J frames. This ammo is no harder on your gun than any other normal 357 ammo. Please don't phone us and ask if this ammo is safe in your gun. It is, providing your gun is in safe condition for use with any normal 357 ammo.
 
We don't recommend this ammo to be fired in super light alloy revolvers as bullets may jump crimp under recoil, but the ammo itself wont hurt these super light weight revolvers. These revolvers are simply so light that the recoil is severe enough to cause crimp jump.
 
The below velocities are offered so that you can see what guns/barrel lengths give what velocities with this new 357 mag. ammo. You'll notice that new S&W revolvers with short barrels are often shooting faster than older S&W revolvers with longer barrels. The new S&W revolvers are very good and are made with equipment that makes them more consistent and faster than the S&W revolvers of yesteryear.

[Vic49]

Thanx Tim, Google Chrome wouldn't let me open it!!!!  I was beginning to think either I was going blind or you guys were seeing things and was pretty sure it was the former.   That is one HOT 357 load wonder what they are burning in those???

[YRUpunting?]

The 49th edition Lyman reloading manual has 357 Mag rifle loads.  The test rifle is a Winchester 94 with a 20 inch barrel.  The hottest 158gr. JHP load they have is 17.0 grains of H110 pushing 1829 FPS.   Some how Buffalo Bore is getting 324 FPS more (17.7% increase) with a 1.5 inch shorter barrel.  The Hodgdon website gives a lower max load of H110 for a rifle than Lyman.  I'm new to shooting rifles, but this doesn't pass the smell test for me. 

[gcrank1]

For some years now ammo factories have had available new generation propellants that are not available as canister powders for reloaders.

[cudatruck]

Again anyone with a chronograph actually shot this stuff? I don't have acess to chronograph yet, was hoping one you with one was willing to spend 1.50 a shot to see if these folks are full of B.S. or if they work as advetised

[bigvarmnt]

A friend once gave me some 158 357 reloads from a gun show. I put six in the cly. of my S&W 66. Shot one and gladly took the other 5 out. I tore them apart and used the bullets and brass but not the powder. I'm afraid they would have ruined the gun or me.
I might have tried one in the Handi
As was said, they probably have a space age powder that we can't get. You guys try them and let me know

Before ya'all get too excited about the BB Heavy 357 Mag ammo, take a look at the downrange ballistics compared to 30-30 factory ammo, both 150gr Rem and 160gr FTX Leverevolution, the LE ammo has almost as much energy at 300yds as the BB ammo does at 100yds, the 357 mag just hemorrhages velocity so bad due to the poor BC.

Another thing that intrest me is that i just looked at bulletsbytheinch and with the 357 mag the 16 inch barrel actually was faster than the 18 and 20 inch barrels in the same caliber. Is that due to the pistol caliber pretty much being spent by the time it reaches the 16 inches and the extra is waisted barrel length. Also I would think does twist rate have a little to do with that.

[cudatruck]

but look at the energy levels at 100 yards. its still a pistol caliber 1073 at 100 yards is not going to be that far off 1200ish for the 150 gr. bet the animal won't know the difference Still wondering what these folks would do the 357 Maximum?
