You can likely come up with a sub load for IMR 4227, but it’s not ideal. H110 is even worse. They both work great for supers though. 1680 is still the gold standard for subs, IMO. Lil gun, CFE Blk also work well

Edit to add, this is assuming heavy bullets in the 220-245 grain range. Things may be different if you’re loading lightweight subs
