[QUOTE="BountyHunter, post: 103775, member: 12"] Sinclair makes a chamber length guage for specific calibers. It costs $5.95 each. Part number G-308 is the 30 cal at [url="http://www.sinclairintl.com"]www.sinclairintl.com[/url] The use of this tool is to put the guage in a fired case and insert into the chamber. If you leave the plug extra long it will seat back into the case at the exact length of your chamber and not what some book says. It is not uncommon to see as much as .030-.050 difference in actual chambers vs the book. That longer area will catch carbon and be very difficult to get out. This will be the start of the dreaded carbon ring. If you are trying for extreme accuracy, you want to case length to be as close to the throat as possible. Therefore an adjustable case trimmer is necessary, which leaves out the Lee's The forester and wilson are the top two IMO. I have used the Forester for over 30 years but am looking for a good used wilson with micrometer on Ebay. BH [/QUOTE]
