as noted further up in the thread... if you crimp.. having a consistent case length is going to be critical to getting a consistent crimp on said loads. so while there's validity to the fact that many cases can probably do without it, there are specific cases where trimming really makes sense and is almost manditory.

such is the fun of reloading though - we can cater our process to suit our individual needs for each of our very unique firearms smile
All reloading info shared is based on my experiences in my guns. Follow safe reloading practice and work up loads from published minimum data.
