My 1911's: Kimber eats everything, Springer don't! Questions are:

[Buckskinner]

My Kimber Custom CDP II feeds everything. I never have a problem with any ammo or mags.

My Springfield Loaded loves FMJ, and most HP. It will load the first round of SWC off the mag, but never another. I can slam the back of the slide home most of the time. But that hurts after a while! The rounds that don't chamber show a shiny ring at the top of the shelf before the trunk of the nose, if that makes any sense. The ring goes around almost 100% of the bullet.

I reloaded a few hundred lead SWC, that only the Kimber eats.

?: If I wanted the Springer to have a less delicate palate, what actions would I take?

I may just say "Well, okay, only feed SWC to the Kimber", as in the future I will only load FMJ or HP. I just had a box of SWC around...

I'd call Springfield. Both of mine feed everything, and my 1911A1 will feed empty cases.

You might have to send it back to them, but they should take care of it for you under their warranty.

Jammed SWC

The rounds that don't chamber show a shiny ring at the top of the shelf before the trunk of the nose, if that makes any sense.

Howdy Buckskinner,

If you mean the shoulder of the SWC bullet...the full diameter just behind
the bullet nose...it makes sense.

When the round hangs up...is it almost fully chambered with the slide just short of going to battery? That "ring" sounds like the front of the bullet's shoulder is making contact with the chamber shoulder...the step inside
the chamber that the case mouth headspaces on..or maybe even being forced into the leade...the cone-shaped area that makes the transition from sharp shoulder to the rifling.

Lead SWC bullets and some designs of lead round nose slugs have a full-diameter shoulder...It's called a driving band. If the bullet is seated too far out, the full diameter driving band will hit the chamber shoulder before the slide goes to battery. In your case, it sounds like it's only a few thousandths of an inch. Try seating the bullets about .010 inch deeper into the case and try again. The pressure shouldn't be high with lead bullets unless you've really got'em smokin'.

I have an old Auto-Ordnance pistol(Ya'll don't laugh! It's actually remarkable for an AO) that has a minimum chamber depth, and will not
handle cast lead bullets with a shoulder unless they're seated nearly flush with the case mouth. I'll drop a finish reamer in the chamber one of these
days...if the guy who borrowed it will ever bring it back...

Try that and see if it doesn't do a little better.

Standin' by...

Okey doke!

Don't hold your breath. The backyard pistol range is still on order from Cabela's, and my leash doesn't get unclipped too often these days...

But I'll try the deeper seating, and get back to ya.

Thanks!

I think Tuner is spot on! Sure sounds like the shoulder of the bullet is wedging into the bore throat.
