What kind of shooting are you going to be doing Hurley? Is there any laws that restrict powers, projectiles, ignition systems where you hunt?

Since you want a thumbhole stock, I am not sure if the Omega Z5 comes with that. That might be an extra you need to purchase. Although I will not swear to that fact. I guess of the two listed I would get the Thompson Center. I would load it with 100 grains of powder and a 250 grain Shockwave and go shoot it.
