Thread: Gong Recommendations?

Have never tried gongs but Looking at picking up one for some long range practice with 7mm RM and .308. AR500 seems to be the common material after quick google. What range would you have to push these out to to avoid destroying it in short order? Would like to try 500-800m but needs to be fairly portable so reckon a 300mm wide one would work?

Before I head off to local gun shop any other recommendations for where to pick one up?
