Not for those calibres but for .270w, .222rem, .308w and 8x57irs with good results using Tu2000, SP7 and Tu5000. I've also used BA10 and GM3 with .38spl and .357mag.
I would use them again if I could get them but supply has always been patchy, you don't come across them very often and the distributor ( Peter Lawman) was next to useless. I had heard a rumour that Lyavale the importers were going to push these powders more in the future but haven't seen any evidence of it so far.
