I shoot round balls more than any other projectile , they're relatively cheap , get the job done , and they perform predictably . I shoot .50 and .54 calibers , the .54 is my favorite . I got two deer this year , a buck fawn(mistook for doe) , and a good sized spike . The fawn was taken with a 3/4 oz. 20 guage slug , the spike was taken with a .54 round ball , the first ran considerably further . I do try sabots occasionally , but I always come back to round balls . My preferred brand is Remington .
