My nephew has a new to him Winchester Model 100 in .308 Win caliber. I would like to do some reloading for him, using cast boolits if possible. I've reloaded lots of .308 Win cast loads (Lyman 311291 and 31141) for bolt actions, but never for a semi-auto. These loads would be used for some informal close up target shooting only . . . in this case function would be my main objective. Will cast boolits present any problems in this rifle? Any tips or suggestions would be appreciated.
