[QUOTE="AZShooter, post: 712184, member: 5219"] I read your detailed explanation. If you had said WSSM instead of WSM I would not have made my original comment. As to using the 25 WSSM for a 30 that would be very interesting and you'd have a very long barrel life too. I have a 30 BR and it has a slightly longer throat than the usual Robinett version. I seat a 168 SMK out to neck shoulder junction and get 2250 or so with a 24" barrel. I also took that reamer and made a 30BR/308 by going deeper and using a 308 headspace gauge. It has to have the neck wall turned to .0105" to fit the narrow chamber neck. It has a steeper shoulder angle and less body taper. I just fireform 308 brass. I use a RCBS FL die without the sizer ball and get .002" neck tension. It shoots the 168 SMK at 2600 fps very very accurately. It is amazing considering the nasty SS barrel I am using that has deep pits that look like city potholes from a bore scope. It was one of my first chamber jobs done by me and my funky 50s sheldon lathe. Lots of fun. A 30 WSSM would be the next bump up and should be very cool. It will cost a bit to run it with special reamer/dies etc. But who ever said that should stop someone. Be sure and report back when you figure out what you are going to do and later on when it is completed with details. [/QUOTE]
