BB question

Hi saltysteve
I'm no expert on BBs by any stretch of the imagination, I think you mean as far as manufacturing
tolerances are concerned? I think they would be no different than the problems we suffer in the
pellet world, some brands are pretty good and others can be rubbish, that's why so many of the
airgun guys spend so much time testing different brands through their guns, although we have 
another problem because our barrels are rifled and different rifled barrels prefer different pellets.
The BB guns are smooth bore, which creates it's own problems because the projectile is not 
stabilized, i.e. no spin is induced on it which makes it's trajectory and placement unpredictable
just like the old muskets.
Hope this helps.

Here's a review that has different bbs tested for accuracy with the tested pistol-Looks like the Hornady Black Diamond gets high marks.

of all the BB's I've used The Daisy Zinc chrome plated have been the best and most accurate
