Did JSB used to have a patent on pellets? I mean they always had distinct pellets but now like H&N came out with 18gr and 15.9gr just like the JSBs and JTS is making comparable ones now too. I didn't know if something ended the last couple years that now they can make "copies" essentially. I welcome it as ive personally seen a decline in consistency with JSB over the last few years in the 18gr which turned me off them completely and now only go for 15.9gr versions. And many people have had issues with the MK1 and MK2 Heavy .25s and of course the .22 MRDs.
