I use a Daisy Red Ryder BB Gun.
Marksman 1010 is the cheapest and slowest BB gun on the market.
one that you can afford
Impossible to answer. You don't define what "best" means to you.
Nerf gun
If its a BB Gun, Then Yes.
You get what you pay for.
There is none!
NONE! this is a pellet gun not a BB gun. Using any hard BB will ruin the rifling in the barrel and make the gun inaccurate. Read page 6 of the owners manual it tells you how to load the gun and says nothing about BB's. It should shoot pellets only.
It all depends on the model. It is best to follow the manufactures instructions that come with the BB gun. Be sure to always follow the safety instructions.
The Current best are Well, Tokyo Mauri, and Airsoft
BB guns are not designed for hunting. The best you can do is kill small rodents.
