[QUOTE="Wild_Bill, post: 2175602, member: 4785"] Hi your cartrige will headspace fine with the Wby shoulder. All of the Wby chambers we cut we show the customer how to full length size without regard to the belt so they only bump the shoulder max .002". As for the shoulders they do not give any advantage at all and most benchrest shooters using Wby cases change to a conventional shoulder between 35 and 40 degrees. Remember when pushing a shoulder of a parent case back to gain a longer neck you will likley get doughnuts so internal neck reaming might be needed. I prefer not to neck ream because a nice drawn finish is more consistent for projectile release. RCC could likley make you brass however it is expensive. I have designed wildcats from basic cases with 60° shoulders plus used the SMc case design with the full radius shoulder it is great to have something to have design input into and a great learning excersize. When you get your chamber reamer get a sizing reamer then your gunsmith can make you a sizing die. For a seating die get a 7mm rem mag Forster seater and your gunsmith can run your chamber reamer into the sleave. Hope it helps Cheers Bill [/QUOTE]
