S&W Performance Center 10mm & Hardcast Ammo

Well shot my S&W 2.0 performance center 10mm today with my home brewed 200 WFN-GC hardcast ammo.

Only took one 15 round magazine with the bear ammo as I was expecting the worst. But low & behold it ran like a champ. Function was as smooth as silk, this ammo hits hard! Recoil was definitely there but the porting controls muzzle rise better than the G20.

As another plus the longer barrel on the Smith got me up to 1200 fps on the Garmin, the G20 runs this ammo @ 1150.

Good day all the way around.

Galloway Precision makes stainless steel guide rods that work on this model. From what I have read, stock is around 17 lbs, which seems light if the intent is to always run solid 10mm loads. I'm running a 24 lb recoil spring in my PC, works fine, reduces recoil, and has to help save the frame over time.
 
I'm glad that this thread popped up. I have had no issues at all with my M&P 10mm 2.0 (4.6" bbl.) since I bought it in 2022, but I've only been shooting FMJ, JHP, and Black Hills Honey Badger ammo. I've wondered about which cast bullet ammo I should try out before heading out into the woods and bear country. I'm going to pick up some Double Tap Cast 200 gr. and 200 gr. Federal Solid Core ammo and see how they perform.

I might just do that.

I did upgrade the Glock 20 to a stainless steel guide rod, can't remember the exact weight, seems like I went from the stock spring weight of 17-18 lbs to a 22 lb.

Can't really tell anything from shooting with one or the other installed but if it's better for the long term health of the pistol it's worth the investment.

Good call, those are the 2 brands of factory ammo I'd try 1st myself. Hopefully they run well in your 2.0.

I don't know about Black Hills Honey Badger ammo, but I do know that my M&P 10mm 4.6" won't shoot Double Tap 200 grain Hard Cast without jamming and/or dropping the magazine.
Even with a 22# recoil spring and stiffer magazine springs.
I now have a 24# recoil spring in it but haven't tried it yet.

EVERYTHING ELSE I've fired in it has always worked just fine, even before I made any changes to it.
 
Like I stated in ost#16, no bears in the area. But I do have about 1K of various 10MM ammo on hand. here is some of it by various manufacturers.

Interesting thread. I'm curious on function and feeding as the 200 WFN-GC heavy lead is about the only thing I'm planning on shooting in my 2 pistols in 10mm.

Curious as about 25% of the guns just won't run this ammo. Is it the magazine or the internal dimensions of the pistols mag well?

Love to hear S&W take on this subject. They might have an opinion but we may well never know....

Going to load up 50 of my bear loads with the practice bullet from Montana Bullet Works it's their 18 Brinell black coated 200 WFN-GC.

Same everything as my bear loads just a non heat treated bullet. Will run 2 full magazines thru the 2.0. As I'm using brand new brass they should function @ 100%, at least that's the hope.


Stay tuned.20241105_151954-270x340.jpg
 
Just use 200gr FMJs if Hardcast won't run reliably.

A 200gr bullet is what the 10mm Auto cartridge was designed around, if you feel that you need more than a 200gr .40cal projectile traveling at 1200fps to drop a bear, then I suggest you move on up a notch to .45 Super/.450 SMC if not .460 Rowland.
 
I'm comfortable with a 200 @ 1200. Just want to confirm my pistol is into it as well.
 
Anyone have luck with the Underwood 140gr Extreme Penetrators?
 
The issue with the magazine popping out with heavy bullets can easily be fixed most likely with a heavier mag catch spring. What's happening is that the heavy bullet has enough inertia during recoil to pop the catch loose from the inside.

One poster commented that his gun jammed when he held the mag catch in to keep it from dropping. The reason for this is that your bullet stack is unable to push past the mag catch and the slide meets the top cartridge when it is sitting below the feed lips.

I would first work to a shorter cartridge OAL to find a length that clears the catch without touching it. If the problem persists, then I would go with a stronger catch spring.

Good luck.

That's good advice, sounds like you've been there done that.

My WFN-GC ammo is loaded to a less than maximum cartridge OAL. Its seated out far enough I can taper crimp on the flat edge of the bullet before the nose slopes inward but just so. That could be the reason my 2.0 operates with this ammo type without jamming or auto- ejecting my magazine.

Testing is ongoing, I need to know this stuff will work as reliably as l can make it & the gun can take it

Good advice. Reliability is the #1 priority.
FMJ are out of fashion and I suspect SWC loads, especially if labeled hard cast, may have been granted a charitable reputation in some circles.
That said, my woods loads tend toward SWC, flat nose soft point or XTP projectiles.

Not with an M&P, but yes, it has happened on occasion.
My 10mm of choice these days is a 6" Witness Hunter. The mag design keeps the bullets far away from the mag catch. My other 10 is a Rock Island Tac Ultra HC with a fully supported Nowlin barrel and compensator. Both make even the heaviest loads a breeze.

I'm the one who did this.
I too thought it was just a case of the bullet corner hitting the mag catch, but it isn't.

I only partially loaded the magazine so that all the rounds were above the magazine catch so they couldn't hit the magazine catch..
And it still jammed AND popped the magazine out unless I held in on the mag release button from the opposite side.
YET all other ammo I fire through this pistol worked fine, even before I did any tweaking on it.

I did find that these Double Tap 200 grain hard cast rounds are a little less than the minimum OAL for the 10mm Auto.
