I notice you're using paper patched bullets. I know the Capt is a staunch advocate of such. On your first target I can see your bullet was 335 grs but I can't make out the rest written next to it. Was it a reference to a particular mould the bullet was cast from?

I'm curious as I'm going to have to pursue regulating two .500's in the future and I'm informally compiling notes of all the info I can.

Many Thanks - Marc
