Win/64 said:I allways thought if it doesn't burn all the powder it doesn't reach the maximum velocity.
So did I, and this seems to be the case with slugs, but there seems to be something different going on with shot/pellets.
Maybe is is a simple matter of projectile cross section having less air resistance when it leave the barrel, but that doesn't explain what is going on to reduce velocity out of the longer barrel.
Or for that matter what effect chokes would have on velocity.
More research is needed.
