[QUOTE="340PR, post: 2291548, member: 107814"] My opinion is that you should trim off of the shoulder dim. There are several trimmers that use this method. First you need to have control of your shoulder bump (setting -.0005 is acceptable for me). Then, your trim dimension should be within +/-.0005. How does this affect the overall reloading process? Not much. You only want to be off of the neck/lands junction in your chamber, to keep the neck from binding against the step. The shorter the neck in relation, the more carbon build up you will see. The chamber diameter in relation to the neck diameter has more bearing on accuracy than length. That is why some shooters use custom reamers and or "neck turn". As always, consistency in the process is much more important than how many +/- .001" any step produces. Whatever your process, follow it religiously, and you will have better control of your ammo. That said, I use the Frankford Arsenal case trim prep centers. Having tried numerous others, these units are economical, and allow the throughput I want, combining the multiple heads to process various operations in several calibers. A bit noisy and clunky looking, they work great for me. [/QUOTE]
