Sig P220 Jamming

My Sig 220 seems to jam every 3rd or 4th shot with my reloads. So I tried the same reloads in my Springfield 45 and after over 100 shots, no jams. I went back to the Sig and jammed right away. With new ammo, it is flawless. Is there something about a Sig that it has to have perfect ammo because I reload all my ammo. Can't afford new stuff.
Thanks

Thanks. I only shoot round nose but I am thinking it has something to do with the ejection operation. The spent cartridge will be in the chamber and the next round will jam into the spent one.
From your description, it seems to be a extractor problem. As the slide comes out of battery after the round in the chamber is fired, the extractor pulls the fired case out of the chamber, then it's ejected after the slide recoils far enough that the rim of the fired case hits the ejector. If it's not doing that with your reloads, and the extractor functions OK with factory ammo, I believe that your reloads aren't loaded hot enough.
The spent cartridge will be in the chamber and the next round will jam into the spent one.A semiauto pistol must perform four functions - feed, fire, extract and eject. The fact that your spent case is remaining in the chamber indicates that - for some reason - it's failing to extract.
When trying to clear up any sort of stoppage ussue the first step should be to return things to zero by completely disassembling and cleaning the gun thoroughly.
The reason for this is twofold. Cleaning alone often clears up semiauto stoppage issues but before actually diagnosing malfunctions of any sort of machine you must insure that it's operating in absence of outside influences. The issue with your pistol may be something as simple as brass shavings built up in the breech block's extractor channel.
As an armorer, if a 220 with the problem you describe came into my hands I'd first check the chamber for eoughness, burrs or other flaws. If it all looked good I'd drop the breech block out, pull the extractor and clean/lubricate. If the situation still existed I'd replace the extractor.
A new one runs about $25 and takes only a few minutes to swap out.
Sounds like an extractor problem or the load isn't hot enough. What is the load?
