I believe SK also makes Wolf. My 10/22 shoots the Wolf match extra alot better than the SK, but the guys I shoot with really like the SK standard, as well as the rifle match. You have more to choose from with the SK and the prices vary. The last brick of Wolf match extra I bought was 2.79 a box, and the Wolf match target was a 1.99. Pretty cheap for match ammo, but the only problem is finding someone who has it in stock.
