[QUOTE="dok7mm, post: 1146637, member: 90080"] Based on my experience, you do not want to be anywhere near the lands with a 7 RUM. It looks like the standard freebore of .300" - .500" is crazy, but with this round, you need it to control the huge pressure spikes you can easily run into. I would consult several competent smiths familiar with the 7 RUM, PRIOR to going shorter than .300" freebore on your reamer. I found the Berger Classics and Hybrids to take the long jump very well.
