The reloaders has 5 options when using the Redding shell holders.
Without the Redding Competition shell holders I have 25 options from minimum length to infinity or a more practice .020" longer than a minimum length/full length sized case. AND! I have the option of sizing cases for short chambers, when using the RCBS shell holders I have 10 options.
And I am lucky, my cases do not have head space, my chamber has a head space dimension from the datum to the bolt face, I off set the length of the chamber with the length of the case from the datum/shoulder to the case head.
You do not have to thank me for my efforts but those that were going to take you seriously got a lesson when taking advise on the Internet. There are a lot of lonely reloaders on reloading forums that take themselves too seriously; they got a poor start and never caught up.
