First off it is so addicting! It is so much fun to go out with my 17 year old son and shoot. I have modified chokes in both our guns, is that the right choice. I guess I'm not the brightest when it comes to this sport so I'm sure my next question wll be stupid. What does the shot mean on a box of shells? I have been using 2 3/4 with 1 1/8 load 7 1/2 shot. Only because this is what someone told me to buy. Would this be an ok choice? Sorry for my ignorance on the matter but thanks for any help.
