Another Quick reinforcement question.

Hello again, I'm wondering if anyone has had their Longshot shell break under a heavy spring load. I've searched it up, but haven't found any problems about it. If that's the case, then if is necessary to reinforce the actual Longshot shell under a 7kg spring load? Also, how much spring weight can the stock shelI take? I want to make sure my blaster won't break anytime soon.

Thanks

Bubba
