Need help with a Nova 20ga. I've volunteered to help a friend's 13 y/old son get his first bird. Not a lot of money to spend on trying choke/shell combos. Question is do any of you have experience with a combo that worked well out of a 20ga Nova. Experience involving the factory full choke would be even better. He had some Rem Nitro 5s we shot tonight. 25yds was max for that combo. Any help is greatly appreciated.
