They are still rebadged H&N barracuda, but a few years back the Magnums started becoming available in head sizes 51,52,53 rather than the generic 4.5 or 5.5 you usually see on the bottom.
Check your tins they will likely say baracuda on the bottom and now a head size.
So long as you stick to the same of whichever size it prefers you should likely see no difference.
My old rapid barrel shot 52 ok, 53 was too hard to load and 51 were an absolute laser.
51 then further sized manually with a pellet sizer was positively cheating lol
