[QUOTE="Hugnot, post: 2910221, member: 115658"] I F/L size all my .300 WM brass. No head separations - I use a .006 feeler gauge between bottom of die & shell holder to prevent excessive case squashing. I always use the same shell holder that lives in the same box as the .300 WM F/L die. Head space on shoulder. I never had a case separate on 1st firing. I try to buy cheap once fired brass. A .002 length growth upon F/L sizing sounds reasonable. Using the .006 feeler gauge between shell holder & bottom of F/L die maintains head space at shoulder with successive sizing. I ignore the belt, sort of useless with cases having moderate angle shoulders. Upon firing, pressure happens everywhere. I remember seeing gauges used for sizing belted cases, the idea being, sized brass should be flush with the top of gauge. A .458 WM needs a belt. Seems like belted ammo is not intended for re-loading - shoot and toss. There are "long" belted cases available. [/QUOTE]
