Question about rifle brass trimming

[Leadlobber]

I load .223 , after resizing / de prime.I start measuring the brass , book says to trim to 1.750. I cherry pick the ones closest /work those, & set off to the side the longest 1.765 + longest was 1.773.{I'll use the Lee tool & hand drill for the longest}

I took the longest case [.020 too long] & it chambered with no problem in both a Rem & Savage bolt gun . So that has me wondering I have never fired a case that long I always trim if they get over 1.760 . Am I trimming too often ??

This is once fired L.C. brass I bought & am going thru.

Some guys never trim! If it's over 2.750 and you trim it then you can't be trimming too often
