I'm not sure a 1/2 and full choke is a bad thing for trap?

As I have only once tried to put the magnetochrony on the drilling and it didn't work because of the taper I have no idea of the velocity but my guess is its okay for 7cm high at 100m for a 200m zero using 175gr interlocks. Seems to kill most things it is aimed at, so I'm not going to panic if its a few fps short of its potential.
