Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area, as rebounding ammo can hit them, too. Never shoot steel BBs at hard objects (including metal targets) or water, as that increases the chance of ricochet.
The great thing about multi-pump pneumatic air rifles is that everyone gets to shoot because you can pump it up to whatever level of strength or endurance you have. Crosman's M4-177 has gained a faithful following but not just because it's a multi-pump…but because it looks and feels like the venerable firearm it copies. The versatility built into the gun is also a big plus. From the telescoping buttstock to extra Weaver rails that encourage you to mount a flashlight, laser, dot sight, scope and/or bipod -- you'll have a blast dressing it up or just shooting it as it comes with open sights. Make the M4-177 your own and use it to make lots of holes in paper targets, take out dandelions puffs and more.
You can never go wrong buying a multi-pump pneumatic. That's why they've been around for so many years!
