Brad, I have no idea if they changed them. My 270 was purchased last spring(shiny trigger/aluminum trigger guard era).
I will say this, the 243(84M) feeds quite a bit better than the 270. The 270 takes a little effort on the bolt. Not even in the same league as my old ADL, that thing cycles cartridges like a dream. Of course it's also a longer action and no doubt that makes a big difference.
