Don't think so. The two 301's in premium steel that I can think of were special runs, one for BCCI (BG-42) and one for Blade Forum (CPM-154).
As for 303's, Camillus used 440A, Buck took over production late 85 and used 425m up until 1992 switching to 420HC as the current steel.
The 425m knives might be the best performers and have a flat grind.
