[QUOTE="FURMAN, post: 1830587, member: 26535"] The 300 WM SAAMI chamber is a weird one to me. It has very little free bore(around .012) and it is sloppy. Because of the slop the lead actually allows a 215 Berger to be seated out quit a bit to touch the lands. Rhian's reamer is much tighter for theoretically improved accuracy and has a better freebore/lead. I will have to go look up numbers but I am pretty sure I was still within the 3.7" Rem mag box but mine was a custom action with a Wyatt box installed. The only advantage to a Wyatt box is if you truly need it to allow a bullet to be seated out far enough to reach the lands. If you don't need it it is of no advantage. [/QUOTE]
