I have some new Winchester .357 Mag brass that I am using as a first time reloader to learn my tools and technique. I uniformed my primer pockets and deburred my flash holes and was measuring the case length to see if I might need to trim the cases. However, the book length for the cases is 1.290" but most of my cases are 1.282 with several being within 0.001 of that but a few being within 0.003. I can trim for uniformity, but my question is whether the case length is too short for use. For general purpose rounds, all this prep might be overkill, but again, I am trying to learn my tools and technique. What if these loads were for shooting targets and defense, would the case variability I described produce suitable loads?
Too Short New Brass?

Re: Too Short New Brass?
Book length is the maximum allowed length. Or rather the "never to exceed" length.
Don't bother trimming those cases for uniformity. Just keep them under 1.290.
You're going to find that straight wall cases don't really stretch much.

Re: Too Short New Brass?
all that case prep is really not necessary for pistol shooting at pistol distances, save time doing that and dry fire instead, that is the best way to get the most accurate load out of your pistol.
all that prep is necessary for long distance rifle accuracy, complete waste of time for pistols.
