I use the RCBS military crimp removal tool chucked in a drill. For me it was a quick fast cheap option and I bought it local which meant no wait for me. It may be more time consuming (but it really is pretty quick) but it’s a one and done thing. Processing 1000+? Sure it may be an all day chore but after you shouldn’t have to use the tool on the brass again. Plus it’s small and easily stored away taking no bench space
