I have a Browning Maxus I would like to set up for turkey hunting. If I want to use lead shot, does that change the restriction of Choke I need? When I asked about heavy 13 people said I should use a .670 -.675. Does lead require a smaller restriction such as a .665? I would most likely use the Winchesters. I was thinking either a Jelly Head or IC? :help:
