This ^^Aluminum cases shoot fine in semi-autos
folks that reload will avoid it as brass is preferred to reload ...
Didn't know that, thought you couldn't reload alum. Thanks for the info.I reload the aluminum cases for my Winter shooting. When I am out on the snow covered Sage Brush range fired brass is gone when fired. The local gun club range has piles of the aluminum cases on the ground. I have never had a single problem with jamming or set back. I only load it once and save my brass cases from loss. It works.
I've had multiple CCI factory alum ammo cases split in multiple revolvers. I realize the OP's question has to do with semi-auto.That is interesting. I have never had a case split "open"?
While aluminum CAN be reloaded, the issue lies with the malleability of the metal. Aluminum doesn't take to "rebending" nearly as well as brass in particular.Shot a lot of aluminum cased ammo. Never saw an issue in 9mm and .45ACP. I also have reloaded aluminum cases with not real problems. They need to be inspected carefully just a brass cases. They seem to have a shorter life in terms of the number of times they can be reloaded.
That is interesting. I have never had a case split "open"?
