I have a friend that handed me a box of these last year . I just put them in the gun case and forgot about them . I got them out and tried them out for the first time at the range and they gave me good results . I think I might give them some field testing this year in my flintlock . I was thinking about going with patch and round ball but since I have these I think I will give them a going . If any one can give me any thoughts Good or Bad it will help .
