Whilst Accupells are fine in a TX when you are loading one at a time I would be careful about using them in a magazine such as the 410 has. I don't know how different the loading into the breech is, compared with my S400 on which I have a Rowan magazine kit fitted, but I find short pellets like the Accupells tip over and can get jammed in the breech unless I tilt the rifle muzzle upwards whilst feeding a pellet into the breech.
