My 20 guage did well with the choke that came with it! I tried shells and chokes and nothing worked. My best friend was looking for a gun and told him i would sell this one but i was still patterning it. I bought some tss apex and kept factory choke in - shot like a champ. Forget numbers but it was something like 80 something pellets in head and neck at 42 steps. Since i had already told him i would sell it to him - i sold it 😀
