I have a buddy wanting to off load about 300 shells. 20ga, 2 3/4", 7/8 oz, 7 1/2 shot, 1210 FPS, Federal Game Loads. Is lead allowed in OK for Dove? My shotgun knowledge is not on par with my rifle and pistol knowledge. With the ammo shortages, etc my buddy is asking for a fair/normal price. If these can be used in OK for Dove, what would you offer for box of shells. He as 12 boxes of 25 per or 300 shells. Thanks
