Just bought the grandson a new 20ga. 870 Youth Express with a 21" barrel. It has a modified choke in it. We have shot the gun and he really likes it. I did change the recoil pad and put a Sims air-tech on it and it makes a world of difference.I haven't patterned it yet we just shot some bottles of water and I know I will probably have to buy a new choke for him to turkey hunt.Any suggestions would be helpful.I don't believe since this will be his first year turkey hunting I should get one real tight,because he will probably be a little nervous . What choke do you guys have any experience with on a 20 ga.?
