Hello there, I got a recommendation for an .38 spl wadcutter load; 148 grs. HB-WC copperplated, Fed 100 primer, Overall length 30,2 mm. And 4,2 grs. of Hodgdon HP38.... Isn’t 4,2 not way to much for a 148 HBWC? This is the first time for me using the HP38 powder, so i’m not familiar with it’s characteristics. Load is supposed to be a highspeed, very accurate load. will be fired from a 6” Smith 686. Thanks in advance!
