I use titegroup in 9mm , but in such a small case a double charge would be easily seen , that is if using a reloading block and a single stage press . In the 38spl case , " where did the powder charge go ?" . It's such a small charge in such a big case it simply disappears . A double charge would be very very hard to notice . I view reloading as a hobby , so time spent on the reloading bench is not a consideration . If I was shooting competition on weekends , different story . I knew a guy that went through over 50K rounds a yr . He has 3 dillions , 2-550 and 1-650 . Today , they sit idle as he quit shooting , completely . I have seen this happen before , " burn out " .
With my single stage press , I don't make ammo any faster than I did with my Lee Loader Kit . I enjoy it as a hobby and I like to keep things simple . Regards, Paul
