7MM Remington Ultra Magnum (RUM)
$170.00 – $210.00
Reamers are available in both Roughers and Finishers with a Solid Pilot or Removable (Live) Pilot. Pilot Bushings to nominal bore diameter are included with removable pilots. Additional Pilot Bushings can be purchased under Pilot Bushings.
TiCN Coating, formally known as Titanium Carbo-Nitride coating, is an all-purpose strengthening coating that does especially well with cutting applications. Adding a total thickness of approximately .0001″ – .0002″ (2 – 5 Microns), TiCN coating will lengthen the life of your reamer and keep your tools sharper for longer.
Oil grooves are an available option for all chamber reamers over 22 caliber. The grooves allow for a better flow of cutting fluid as well as flushing of chips.
The 7MM RUM is made to SAAMI Specifications.
The 7MM RUM uses 300 RUM headspace gages. The 7MM, .300 & .375 use the same headspace gages. SAAMI denotes them
differently, but they calculate out to the same .400 datum.
The .338 RUM has it's own separate gages and headspace specification.
