Yes very much so. Most Match Shooters don't eat or drink Caffeine for several days before a match
YES! Especially CO2 systems.
A BB gun uses compressed air to push a round steel "BB" out of a smoothbore barrel. It does not have the power, range, or accuracy of a firearm.
Really .25g bb's will have slightly improved accuracy, relative to the gun's power and base accuracy alone. And it depends on the weapon, what do you have?
If its a BB Gun, Then Yes.
I would have to say no because the question is for a .177 cal 'BB' gun. If you intend on hunting with air rifles in the .177 caliber, then you really should use pellets. Pellets provide much greater accuracy and are more humane than a BB.
BB gun. Fires a round BB.
Benjamin Breckinridge Warfield did not invent the BB gun.
Which model, what is the condition of the BB gun or is it a BB rifle..
It's a BB Gun.
A BB gun is a gun which shoots BB-size pellets, typically with the use of compressed air, or a compressed spring.
Most BB guns use a "Smooth Bore" barrel. It just a hollow tube for a barrel. They are not consistently accurate. Speed does help some but not much. Pellet Guns and Rifles usually use a rifled barrel, one that has grooves in it. This makes the pallet spin and gives it more accuracy than a BB. There are combination BB and pellet guns made, but they are also smooth bore. I know of one BB/Pellet gun, the Gamo P-23, that is a combo bb/pellet gun. It uses a rifled barrel and special "Led BB's." The common Steel BB will ruin a rifled barrel that's why the Gamo P-23 uses "Led BB's." This barrel makes the BB spin and more accurate. Speed will increase the distance and power of a projectile.
You don't magnetize the BB's. The Magnet is inside the BB gun. The gun has to be taken apart and the magnet that holds the BB's replaced. Not all designs use this method of holding BB in place.
