S&W Performance Center 10mm & Hardcast Ammo

[41special]

Been researching this. The problem crops up with the wider nose of the 10mm hardcast WFN-GC bullet shape.

Somehow the bullet contacts the inside of the magazine release causing an unintentional magazine drop, this of course is less than optimal when pulling down on a grizzly in a life threatening situation.

As this type of ammo would be in my gun while using this particular autoloader it's of interest to me.

Thoughts?

Go to a less "WIDE nose"HC bullet...? I load the MBC 180gr coated 18 Brinell TCFP .401 which work fine in my XDM Elite.

They should do the job?

CHEERS!

There are many manufacturers of "bear protection" 10mm ammo. The bullets around 200 grains or lighter should be fine, I use Sig 180 grain ammo at 1250 fps from my 4" M&P. It's very accurate, has manageable recoil, 100% reliable, and not near as expensive as the boutique ammo.

Try a Truncated Cone bullet design in your auto-loader ...

No matter how effective a WFN might be ... if it won't function properly in your gun ...
you don't want to use it .

Might be a good excuse to buy a 10mm Revolver !!!

They will shoot the WFN with no problems .

Wide meplats on 10mm bullets are a known issue.
More than one 220gr SWC has had to be redesigned.
It's the reason a lot of folks limit their 10mm SWCs to 200gr max.

Good to know.

The load I worked up for my Glock uses the Montana Bullet Works 200 grain hardcast WFN-GC AA #9 and a magnum primer. I really like to run the same load in the Smith.

According to their website, MBW will be shutting their doors unless a buyer is found.

It is my experience that feeding issues can often be remedied by a change in OAL and a corresponding minor reduction in powder without seriously affecting the ballistics of the previously developed ("worked up") load.

Only a few test examples usually can determine if it is feasible.

Cheers!

I saw that....

Mine shoots everything fine other than the wide flat tipped cartridges.

Yes, I was one of the people who did experiments on this as my 10mm M&P 4.6" jammed and/or popped the magazine out when I tried to fire Double Tap 200 grain hard cast ammo with the wide end.
I too came to the conclusion that the bullet edge could be hitting the magazine release.

BUT TRY SOMETHING ELSE.
Load the magazine, but stop loading it before there are enough rounds for the end of the cartridges to hit the magazine release.
In MY M&P, it still jams or ejects the magazine.

NEXT, load the same amount of cartridges and this time, push in one the opposite side of the magazine release button so it can't move.
On mine, pushing on the far side of the magazine release so it can't move prevents the magazine from popping out, but then it always jams with the bullet end jammed against the top of the opening of the chamber.

What I think could also be popping the magazine out is when the cartridge is angled nose up against the top opening of the chamber, she slide is pushing against the back of the cartridge and there is a strong down force as the slide is trying to close.
This could be pushing the magazine down and popping it loose.

I've only ran some 180 XTP @ 1150 with Power Pistol in mine so far. Tomorrow will try the Sig Sauer factory 180 FMJ it runs @ +1200 in my G20.

Now I've talked with 2 other guys with this exact same pistol and theirs will run the Buffalo Bore & Double Tap heavy lead with no issues. So apparently some will & some won't.


So after some break in i'll run the hardcast load & hopefully my particular gun will run it without a hitch

The mag catch is faulty then.
