Ive done a lot of work with bismags over the years  .testing them and looking at performance etc .

They are great in pcps .as they often produce high energy and great accuracy .with good penetration and energy retention  .

However .

In springers the exta weight and head and skirt size .coupled with a firm lead compound can often rob the gun of energy producing maybe 9 fpe .where as  a lighter pellet may produce 11 fpe .

Some springers are more prone to this effect than others. The worse effected tend to be short barrel guns with shorter compression tubes and a lot of spring preload example would be .

Bsa lightening .

Hw 30    hw99  Tx200 hc

 

Guns with longer barrels and longer tubes with  a softer spring will shoot a wider range of pellets at similar energies and poi .examples 

Hw95   hw 80  hw 35 

Bigger  webleys and hatsans etc .

Hope this helps
