All cases should be case mouth deburred after trimming or neck turning. We carry four different standard case mouth deburring tools; L.E. Wilson, RCBS, Forster, and Redding. All tools are double-ended with standard 45 degree flutes that debur/chamfer the inside and outside mouth of the case. They will work on cases from .17 caliber thru .45 caliber. We also carry a 50 BMG tool. The Wilson, RCBS and Forster tools can be used in the Sinclair Deburring Tool Holder under power. The Wilson tool and the Sinclair Holder can be purchased as a kit, which saves you approximately 15 percent.
