I've wanted to try out the IMI 77 grain Open Tip Match clone loading of MK262 for a while and finally picked some up. Overall comparison to Black Hills shows the IMI performed very well. The IMI was a little slower than Black Hills (20-30 FPS), but accuracy was better. Granted, this was a short test (10 rounds of each), but probably a good representation of what you can expect out of the IMI loading. IMI is also quite a bit cheaper and generally seems to be more readily available.
