Well I bought a box of factory 45gn sp's that had been gathering dust in the back of a cupboard, they shot very well too.
Just remembered a load of cases I got off Allan, sure enough loads of rem's (but all K's) I'll have to see what I can get in them
There's also a short article on hornet loading in the Dec Shooting Sports magazine, but not worth especially buying the mag for.
Just did a quick check with my K cases filled to the brim with lil-gun, S&B hold 14.2gn, Hornady hold 15gn, Frontera hold 15.5gn, Rem hold 16gn - I wasn't expecting such variation
