So I just picked up my first gun the other day (Mossberg 590a1) and there is no way I can be paying $5-7 for a box of five slugs. The range I use (the only public, outdoor range there is...) is not to fond of buck/bird shot due to hitting others targets. (I will got on weekdays so there are only a few people and can maybe get away with some buck shot) But I am looking at picking up a case of Federal Hydra-Shok slugs...any one used these? How are they? Or any other decent priced slugs...
