When i first bought my shotgun a long time ago, I didn't know about the different types of shells. Went to walmart and bought a box of those target loads there were about $7-10 a box. Later when I went to the range, not only did I found out I couldn't use this type of ammunition but they became useless as it just sits in my room collecting dust. So I gave it to a friend who thought it be a good idea to take out the mini target load pellets and replace it with bigger pellets. At first I thought it was a good idea but something kept bothering me thinking that it won't work for some reason. Someone enlighten me please.
