Using SWC ammo in semi auto

[JagerDog]

Depends on the gun. My Sig 220 will eat anything.

Gonna guess yours are plated vs. jacketed.

[BigBronco]

Have not tried them in my P220 however my 1911 Randal hates them.

[jmpgnr24k]

G21 cycles them fine.

My rock island GI that I throated will feed empty cases.
It does not even need a bullet in the case!
It will also feed every type of 45acp ammo regardless of bullet style that I have tried in it.

Before my throating work, it would only feed ball.

A semi wadcutter style bullet actually is a good defense bullet, as long as your particular gun will feed it reliably. The flat point, and sharp shoulder transfer more energy to the target than a FMJ. Think of Elmer Keith's bullet design.
IIRC, the original loading for the 45 acp was a 200 gr bullet at about 800 fps. So, a good semi wadcutter bullet in a 45 acp, loaded to about 900 fps would be a very effective load.
FWIW, the original bullet design in the 9x19(9mm P) was a truncated cone bullet. But due to complaints from the Allies during the first World War about it being TOO effective, the Germans replaced it with a Round nose bullet, to be more "humane". But, a semi wadcutter bullet in a 9mm would also improve it.

I used to use SWC bullets in my Bullseye gun years ago.

My xd never gave me issues with any brand fmj. And I trust my cz 97 will eat anything.

The XD should run them just fine. Most people are concerned with using non-RN bullets in 1911's. My XD eats everything. I have a Auto Ordnance 1911 form the 70's that is finicky about SWC's so I don't shoot 'em in that gun. If they aren't seated to the perfect length, I'd get 3 point jams so I only use RN's and cast Lee TL452-230-TC's.

200gr SWC with some 231 is my standard load in my SA Mil Spec. Also in a S&W 625 PC.

[Legasov]

Ran 50 of them today in the XD. Three rounds jammed and the chambering was sluggish. But they're accurate for sure.

200gr SWC with some 231 is my standard load in my SA Mil Spec.

Same everything for me, my milspec eats them up.

Glock advises against shooting lead in their polygonal rifled barrels

Lead build up leading to increased pressure.


Most who reload and have a Glock switch to an aftermarket barrel with a fully supported chamber and regular rifling for $125 or so.

IN my early days of reloading SWC were all I shot. that was before the plated bullet was so readily available. Now I don't mess so much with unplated lead. the cost difference in lead bullets and plated really isn't that large now.

This has been heatedly discussed for many years. If one knows what they are doing, shooting lead, especially coated lead doesn't cause problems. If one uses the wrong lead, meaning undersized projectile, too soft lead, wrong powder, etc, one can end up with severe leading. It can look like one tried to create a layer of solder in the barrel. If one doesn't know and understand what they are doing, anything to do with firearms will be dangerous.
Switching to a quality aftermarket barrel for a Glock can make it easier to have success with lead bullets. It still helps to know what one is doing.

BTW, all manufacturers that I know of advise against shooting reloads in their firearms. Is that also a consideration?
If one doesn't know - don't do it. Glock or other brand.
