Full Ammunition. Black Hills. Federal. What choices are there really?
Even 69gr?
I believe Milarm

puke

imports Blackhills match ammo.
I've tried their 68 & 75 grain match ammo and was disappointed overall.
Federal match is good stuff, but both types will be a pretty penny.
For the cost of a 1000 rounds of match ammo, you could be well on your way to making it yourself.
Here's a breakdown of loading components:
$240 - 1000 cases (new Winchester)
$280 - 1000 69gr. SMK (500 bulk boxes)
$ 40 - 1000 Primers (Fed 205m match)
$ 85 - 3.5 lbs Powder for 1000 cases (25gr. Varget per case)
$645 - 1000 rounds of match ammo using brand new cases.
Reusing cases say 4 times reduces costs to $465 per 1000 for 4000 rounds. Considering White box ammo is going for the $400 mark these days, handloading is a good investment.
