Most of what's been discussed here is largely a waste of time. BTDT.
You pretty much get what you pay for, and you can't make a silk purse out of a sow's ear.
That said, you don't need to shoot the absolute top dollar stuff to get good results. I just got home after winning a 100 yard benchrest match for vintage single shots with my Winchester 1885, in a stiff wind. I shot Eley Match Extra, but I also have had good results with Eley Team, no longer available
. My CZ 452 American is also a consistent match winner, using Wolf Match Extra.

Yeah, $12/box is a bit steep, but most competitions around here might use two dozen rounds total.. So who cares about price?
