What can happen is the added stress on the cocking foot tends to make the foot turn upwards after a while, eventually creating a situation where the foot drags across the spring coils because it's bent or tipped up at the rear. I'm not saying it will happen for sure, but I've fixed a few that had that problem after owners or someone stuffed a high power spring in search of high velocity. RB
