300 Blk - Trying Cream of Wheat and Cotton as case fillers - ep 35
This video details an experiment to address powder position sensitivity in 300 Blackout subsonic loads using Cream of Wheat and cotton as case fillers. The instructor tests various amounts of Cream of Wheat and packed cotton, documenting the significant fouling and cycling issues encountered with both materials. The experiment concludes that neither Cream of Wheat nor cotton are viable case fillers for reliable firearm function, leading to a recommendation for heavier bullets for subsonic applications.
