223 Remington Fullbore T.15


We know bore sizes vary on 22 CF barrels, so alternative pilot bushings may be needed depending on your barrel manufacturer.

Reamers are available in both Roughers and Finishers with only a Removable (Live) Pilot option. 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 223 Remington Fullbore T.15 uses the standard 223 Remington headspace gauges.

The 223 Remington Fullbore T.15 uses the standard 223 Remington Roughing Chamber Reamer.

Designed for Berger 85.5 & Lapua .223 brass (Max case len 1.765).

Freebore note: Due to the 15 degree transition, this chamber has the equivalent of .195 freebore vs a chamber using the standard 45 degree transition. The length of the 15° transition is .0404 longer than a 45° transition would be. Depending on the the lot of Berger 85.5's, the bullet of a cartridge loaded to a COAL of ~2.635 should be just touching the leade/lands. Approx. 50% of the neck will be in contact with bearing surface. Base of bullet will be slightly forward of body/shoulder junction.

Designed with similar proportion of bullet in the neck as the very successful 2013 FTR reamer and with similar throat
geometry to many of the winning ELR chambers.
