Factory Kynoch RN, DWM FMJ, 400gr Woodleigh Projectile, DWM 400gr RN, 404 Jeffery with a 400gr Woodleigh stuff into not very well. The same 6 factory crimp marks are present on both DWM rounds near case mouth, Kynoch has 3 crimp marks half way down the neck. All case have blue sealant ? present round the primer. On the kitchen scales weight were 40grams for 2 case and 43grams. These certainly aren't good scale but they would indicate that yes DWM manufactured a factory 400/401gr 10.75x68 load.
