Re-read the manual. That is a "trim-to-length" to be used ONLY if the cases exceed the desired case length of 0.898". Did you find ANY cases that exceeded 0.898"? NO, because they are rarer than hen's teeth and in my limited time reloading (a little more than 45 years), I have never found one.
You can drop re-sized cases into the barrel and see that they are all a little short of "perfect" head-spacing. Again, the goal would be to have all straight-wall cases that headspace on the case mouth be at the max case length to mimimize headspace--always a desired goal--which your cases now, after a lot of effort, will NEVER achieve. Your cases are all now 0.01" short of "perfect" headspace and will all hang on the extractor if you are lucky.
As far as I am concerned, the 'trim-to-length" for .45ACP, 9x19, etc. is SIMPLY a LIABILITY issue if someone somewhere somehow got a case that exceeded 0.898" and it caused a problem. The manufacturer could point to the reloader not meeting the recommended trim length.
From Lyman: Trimming is necessary when your cases have lengthened after numerous firings. Check your cases after resizing and never allow them to exceed the maximum listed measurement.
Notice they DO NOT say to trim all cases to the "trim-to-length," but simply to never allow any case to EXCEED THE MAXIMUM case length listed--which, for .45 ACP, is and always has been 0.898".
