Is picking Built to destroy and using max charge ammo a bad idea? Would it decay my weapons at a ridiculous rate? I know raul's 75% maintainence perk would help but to be honest i would rather have boone as my follower on hardcoe. Any input would be greatly appreciated. thanks.

Weapons Repair Kits are cheap and easy to make at only 50 repair. At 1 weight each theyre not too much of a burden, besides you can always load up your companion with ten or so

in any case I recommend saving the Max Charge for enemies with higher DT and just relying on baseline MFCs or even Bulk for the bread and butter killing
