Like so many new reloaders, I bought trim equipment for straightwall handgun reloading. Fortunately, I came to my senses pretty quickly, and haven't expended my time so foolishly since.
I use a lot of range brass when loading .45ACP. Other than chunking the offensive headstamps, eg., Amerc, I just mix 'em in with my brass supply, tumble, and reload. Tens of thousands of rounds later, no problems, and I sure don't notice any accuracy deficiencies.
.45 ACP cases shrink, rather than grow, in my experience.
