I always thought the red ones were a little more heavy duty than the orange ones, but who knows?? I will watch the hole in the future. And I will be sure to inspect it before I shoot it again. Tom.

Been reusing my orange disc for a while... Never noticed any prob with my breech plug... But then once a knight is sighted in you dont need to shoot it much... I've prob only shot maybe a 50-75 shots threw mine since I had it...

Thought I'd oreder one of those conversion kits for my knight... Hopefully I don't have any regrets!!! We will see...

If you don't shoot it much, maybe you'd be better off to stick with the orange discs.
