Here is Dave Kiffs company URL.. It has a contact link on the site
suggest you get on it when you can. Tell him exactly what range of bullets you are looking at for example 165-180 Hornady SSTs, Scrirrocos, Norma brass etc.
Define your ideas as best you can and he will mail you a reamer design spec sheet with your name, after that it is about $135-150 and 30 days to have it. Tell him you do not want to neck turn but not as loose as factory chamber.
If you cannot get it, PM me with specs, and return mail address. I will call him and fax the info to him and have him mail it to you ASAP.
Are you out of MCBC LeJeune and 2 MEF? If so guess you are due to come back in March? Two of my tactical Saftey specialists are there now with 2nd MAW and 2nd FSSG.
John Myer at Custom Gunsmithing in Boyce VA has the no neckturn Norma Reamer in his shop now. He is a top recommended smith. Go to www.6mmbr.com
and look under recommended smiths links. His email and POC info is there.
Good luck and safe return.
