What are the pros and cons surrounding neck sizing vs full-length sizing?
I'm referring to using a neck sizing die, not "partial sizing" or just setting the shoulder back 0.002" or so.
I've read a John Wooters text and he said even if one uses a neck sizing die, every 3rd or 4th resizing process one should full length resize or the case may not chamber as expected.
My thought was it eliminates the need to lube the cases, although I still use an appropriate caliber bore mop with dry graphite to lube the mouth.
I thought it might prevent case lengthening, but that didn't happen. My .270 case was 2.530" before sizing and 2.534" afterward. All cases showed an increase between 0.003" and 0.005" and about 10% had to be trimmed. anyway.
Any thoughts?
