Just a quick question...im currently making my tumbler but wondered how much SS pins I will need ....

I'm only going to have 100 or so 243 or 308 or 223 (you get my drift) at any one time, so how much media will I need to get. Also it seems the good ol US of A is the cheapest place to get it (media) from even inc delivery or could one of you guys shed so light on a more local source...Thanks

and very good results btw guys...
