Aluminum-case ammo in my .45 pistols - OK to use?

[trackskippy]

What about aluminum cases in aluminum framed 1911s? It seems that it would possibly damage the alloy feed ramp? Aluminum forms an oxide when exposed to air (O2), aluminum oxide, the stuff sandpaper is coated with. I think I will pass.

I think the steel followers in your mags would be a bigger threat. They were with my one Kimber.

Yes, I am aware of the unsupported (type) steel follower tilting into the feed ramp. I have had several 1911 experts tell me that cannot happened and then I showed pictures of it doing so. On the aluminum case there is not any contact of the case with the ramp, only the bullet I think so you are likely right that it would not be a concern.
