Our greatest area of expertise at Pacific Tool & Gauge is Chamber Reamers. Chamber reamers allow you to re-chamber your current rifle to a larger and/or longer cartridge. Many cartridges accept the same barrel bore, so a re-chambering is often all that is needed to go from a .223 Remington to a .224 Valkyrie or turn your .260 Remington into a 6.5 Creedmoor for example. By upgrading your bolt face and chamber, you can move from a 30-06 to a 300 Win Mag simply by re-chambering and upgrading your bolt face to a magnum.
A Rougher chamber reamer is for when you must cut a large amount of material out to reach your chamber dimensions. You will need a Finisher chamber reamer to achieve the desired chamber dimensions.
A Finisher chamber reamer cuts the chamber precisely to the cartridge dimensions. When retaining the same barrel bore, often a Finisher reamer is all that is needed to re-chamber.
A Re-sizer chamber reamer is for cutting a full length sizing die. If you are requesting a custom chamber reamer and expect to reload, it is recommended to order a re-sizer chamber reamer to have a matched set for precision loads.
