Hmmm. yes I discovered that you can buy factory made 75gr SST cartridges. It's just that I read a review by Potts where he said he'd hand loaded some 75gr SST for a .243 he was reviewing. Thanks anyway.They only sell the 75grain SST ammo in the UK but Hornady don't make a 75 grain SST bullet only the V-max. More of a marketing ploy for us I think.
