My son has a 870 “youth” 18" 20 ga and I am considering using it for home defense for him and my wife.
I have a couple questions:
Why does the “big three” ammo companies ALL use # 3 or # 4 buckshot for 20 ga., but almost everyone agrees on 00, or #1 buck for 12 ga? How effective are the 20 pellet #3 buck loads in 2 3/4"?
Lastly what choke tube patterns the best for the 18" 20 ga? Improved Cylinder? No choke at all?
I am used to having a “smooth” 12 ga riot gun with no tubes
Federal used to make a 00buck load for 20ga with 7-pellets. If you cant find any let me know, theres a hole in the wall type gunshop that had some as a few weeks ago that they’ve for a good while.
Personally I would get them a carbine,light recoil,fast follow up shots,effective stopper. But,if a 20 is your choice I would go with slugs rather than shot.
I have a 20g Mossberg 500 for home defense and I’d recommend AGAINST loading it with slugs for inside the home. The penetration is to much of a risk IMO but I have a full house and this might not be a concern for you. I ultimatly decided on #3 buck as it is shown to provide plenty of penetration at home defense ranges, is milder then 00 buck for faster follow up shots, and it patterns great in my gun with modified choke installed. The fact that it is much more available isn’t a deciding factor but a bonus.
