My gun of chioce is a rem 870 for trap shooting in 20 gauge. some of you may think that a pump is not good for trap but keep in mind that imasophmore in high school and Its the best shot gun I have avaliable.
I also use the 15$ 100 pack of shells from wall mart.

I have two mossberg 500's and i have no ideawhy that would happen but whatever it was good luck
