expander problem ?

The reason I size first is there is chamber measurements from base to end of case mouth , if the case neck is too long to will pinch the bullet in the chamber causeng pressure problems .On every type of case they have trim lengths for that reason . If you trim first then size the case length changes . It is easier to trim first because case mouth is wider allowing the pilot to enter easier , but your not going to get a accurate case length. Do you trim first before sizing?

Chris I size and then trim. The case will not go in the trimmer without being resized first. I use a fantastic Possum Hollow trimmer
 
Why would some size great and a few very hard to extract ?

What a great chance/opportunity to use the term "neck tension" and then there is me: if the neck of the case wants to keep the sizing ball/expander can anyone imagine how much bullet hold the neck has?

I have had cases make that sound; 'thoing' when the expander ball was pulled through the neck and while reloaders are using their imagination try to think about the neck pulling going on and the extra length that is being added to the length of the case from the shoulder of the case to the case head.

Didn't know much about the Possum trimmer , looked it up and it looks like a nice trimmer . 30 years back when I got into reloading I bought the RCBS RockChucker Press and TrimPro case trimmer both have worked out well . When using brass on the thick side caused the pilot entering the case too tight causing a slight scratch inside the case mouth , just chucked it in the drill to smooth it down alittle helped solve the problem . Glad you trim after sizing . Be Well .
P.S.
Just came back from the emergency room , woke up with the room spinning an my right calf swollen . Turned out to be nothing , Vertigo and keeping a knee brace on too long after slamming it into a trailer hitch . CT Scan , blood work and sonogram of the groin and leg . Did scare the heck out of me but it was nothing . It's good talking to my forum friends , always makes me feel good . Thanks Again.
