About the same here, never tried solids , boattails never seeing no need/reason, in a low powered rig. I've only seem them shoot well at a minimum of 50fpe and much better at 90fpe, regular p-ellets rule the airgun accuracy world.
Now if you were to bump it up to 60fpe+ maybe but still no reason for a boattail other than someone wanted a die and the closest dia. the manufactporer had was in a boat tail.
