another source @ .43 per IF you have to shoot corrosive and wanna take a chance from atlantic firearms ammo ....personally i am happy with non-corrosive tela @ .47 per although they did sneak up lately to .51
I bought a few cases of tela , i found it to be not corrosive and seems cleaner shooting than the zoo brands but i have yet to test accuracy at 100 meters , i am sure it will do the job
