4 is fine if you already have it.I found both 7 shot and 4 shot with my reloading stuff. 4 shot is what I will be using until I can get over to Laramie to get the specific loads for turkey. Plan is to repeat this hunt next year whether I succeed or not so I will be looking for turkey specific loads. 7 is what I use on doves. Not sure why Laramie has plenty and Cheyenne's shelves are mostly empty on ammo.
