I keep hearing this but I've never had MORE reloading components and supplies for the .303 British cartridge than I do now. Sierra is back making the 174 gr. SMK, PPU makes bullets and cases, Hornady has bullets, LeHigh has bullets, Hodgdon is selling Varget, BL-(C)2 and H335 direct from the factory, cases; both factory new and once fired are commonly available online. I've recently bought several hundred factory new Winchester and no-name brass that I believe is actually some old Dominion or Imperial brass as well as a bunch of HXP once fired from GB recently.
