Custom 7mm Rem Mag, 24" #4 Shilen, Rem 700, 150 ballistic tip, IMR4831. 3 shots, 1 hole, 100 yards. WW brass, WLRM primers, necks turned. Bullets were all weighed and sorted, as well as brass. Finished ammo was checked in RCBS Precision Mic. I do not use an expander button when sizing brass. I use a carbon-graphite/100% alcohol solution to lube the inside case neck.
