I have been loading 3.9 Grains of Tightgroup under a coated Saeco 372 125gr. round nose cast boolet. It seems to shoot fine but I really don't have much supporting data that I can find in load books. My browser does not support the powder company websight anymore is appears. So I guess I am just looking for conformation that I have a safe load with this powder in 9mm. If the look of the primers are any indication of pressure then they look safe enough.
Anyone else on the Tightgroup band wagon?
