dies neck or full length

[L. Cooper]

Rocky is right about the necessity to FL resize occasionally, but I neck size almost all my loads simply because it allows me to not lube the cases and saves time as a result. I lube the insides of the necks a little, and then run them through.

Once I detect an instance of "hard chambering" in a specific lot of cases, I FL resize and we're back in business.

Need some input from Rocky and other experts.

I tried the partial sizing route with normal FL dies, and it worked well except I think I was trimming cases more often with that method. Do cases get squished forward easier? Perhaps because of less "set back" of the shoulder by a slightly backed off die? Does anyone else think they trimmed cases more with partial resizing, or did I just have another episode of delirium?
