Rimfire Contour List
Listed below are our special rimfire contours that we have CNC lathe programs for. Most of these contour descriptions have a CAD drawing to accompany them. To see one of these drawings as a .pdf file click on the orange highlighted rf number in the left column. The weight is included on the drawing and this chart for each profile as calculated from a solid model with a .22 rimfire caliber hole and using the specific gravity for 416 stainless steel. This weight is for the blank length listed and does not account for weight removed for fitting to the action or chambering.| Updated 3/15/19 | DESCRIPTION | blank length | weight | blank dia. | |
