I recently obtained 300 pieces of virgin RWS brass (at great pains to my wallet) for a new custom .300 WinMag rifle. But having no prior experience with this brand, I was shocked to discover just how incredibly heavy it is. Just to illustrate here, I took 100 pieces of this new Lapua brass I've had for years and 100 pieces of the RWS stuff (both of the .300 WinMag species, of course) and started sorting them by weight, finding that the RWS brass is by comparison to the Lapau brass FAR heavier. While the average Lapua .300 WinMag case weighs around 216 grains, the average RWS .300 WinMag case weighs around 270 grains!!!
Now just how is this going to affect the way I handload? I know, for starters, that I'd better use ALOT less powder in assembling loads with the RWS cases. But what other recommendations does anyone have?
