I've read that when preparing 38 target wadcutter ammo with wadcutter brass, the cases should not be resized before loading. Back in the day when I was a peace officer I shot a lot of PPC competition. I used Remington & Federal 148 gr match wadcutters for competition, but practiced with 148gr Remington wadcutters handloaded in once fired wadcutters cases. These cases were full length sized when loading. As I recall, testing the loads in a Ransom Rest, showed only a very sight increase in accuracy with the factory fodder. I'm retired now and no longer eligible to compete in PPC, so I've started shooting in bullseye matches at our local club. Also found that my custom PPC S&W revolver does very well in bullseye. (Albeit I seem not to be able to do as well.) My only problem now is I can neither find factory match grad wadcutter ammunition nor factory hollow based wadcutters bullets. However I did acquire a Lee six banger that throws a decent looking wad cutter boolit at about 152 grains and .359 from the mold. My cylinder throats measure .358 on the Smith and my bore diameter is .357. My question is , should I size the 2,500 rounds of wadcutter brass or not. Unsized, some of the boolits fit loosely in the case.
