I spoke to a Ladie Letha and this is wat she said.....I would recommend for your gun our Item H378i (1-7/8oz.) #4x5x7 hevi-shot with either either a Rhino .660 or a Jelly Head .660 choke. Whichever choke you choose, you will get between 170 to 200 pellets in a 10" circle at 40 yards. Going to go with the Jellyhead, need to find who has the best deal on them and then I am ordering my shells from Nitro.....
