rifle reloading is very common in Australia shotgun not so much these days I still load low pressure loads for my older SXS's and some other special loads that you just can't buy
the price of factory target loads is around $140 (give or take $10) Oz dollars or about $110 US this is for a case of 500
lead shot prices here have gone through the roof it would now cost $60 for 10KG's of Winchester shot Win 209 Primers are $65 per 1000 powder is around the $100 per 2KG's and wads are around $35 per 1000 not many people are using Winchester factory loads now with Compression formes cases so they are hard to find most people I know who did reload only used the comp formed cases I don't know of anyone who loaded the Parrallel cases (though there were poeple who loaded who didn't know they were diferent scary thought that)
I can see reloading starting to happen again factory loads are starting to go up in price and before long it will be a popular activity again at the moment factory loads are cheap enough so most people buy rather than reload
