Recently, My Springfield has been destroying brass, a bite mark straight across the case mouth, making it useless to reload. Happens maybe twice in an 8 round mag

Any Idea on what the cause is?

You may need to tweak your extractor, but I am not the person to be advising you on how to do that. I am sure someone else with more experience will chime in.

Here is a good page that I had bookmarked:

High lighted in red are two words that stand out in your OP. Springfield and recently. Meaning you didn't have problem before, right ? So what could have changed ? Tension ? Tension in what ? Springfield extractors are notorious for not holding tension. Usually they become too loose. Are you still running stock recoil spring ? You didn't change it recently, did you ? There are many tutorials on extractor tension, previous poster linked a good link for you.

Is the recoil spring new?  How heavy is it?

Stock recoil spring, the only thing changed on the gun was sear leaf which was causing hammer following.

gun ran fine after I put the ED Brown Sear in, this has started in the last 100 rounds

Call Springfield and they will send you a label to Fedex your gun back free of charge.

70.

Just get a quality extractor (ed brown hardcore or Wilson combat bullet proof) and install it.  SA extractors are only useful for pushing crap around on a workbench looking for something.

Yeah, I replaced my sear spring with ED Brown Hardcore, and plan on doing the same with the extractor thanks

I've been shooting walmart .45 ammo for a while and never marked any of my brass, but last range trip I went and I shot a different kind and it marked almost all of them, then I shot some more walmart and it didn't mark any. Have you changed to a different ammo recently?

I pretty much only shoot federal, but its not marking the brass, its crushing 1/8" of the case neck to the point of tearing the brass
