That is a tough one, about like which is the best scope, barrel, action, stock, mounts, boots, target design or gunsmith.
I believe that the answer to your question is determined by your particular rifle. We have some rifles that prefer J4's (believe Wyo is that way also) whereas some shoot Matchkings or Bergers or A-Max. I have gone to the bottom line, whatever match bullets I can get the cheapest so that I can shoot more - as in steel plinking.
You would need a huge sample of rifles shooting a huge sample of ammo to figure that one out - by the time you did someone will have a new bullet out that claims to be better.
Year in and year out, the Sierra Matchking is just plain amazing. Matchkings seem to be taking a beating from some serious shooters here re quality control, but I believe they still set the standard to match or beat for factory match produced bullets.
Seems that the spread between match and hunting grade bullets is shrinking, the factories are making some amazingly accurate hunting bullets these days.
I am heading out shortly for a LR shoot this morning - don't really care which bullet as long as it hits them damn plates.
The accuracy varies among the big manufacturers because of the run of jackets.
If you get a great run of jackets, (No variance in wall thickness) you can make bullets with tremendous accuracy potential. The high volume guys have a larger acceptable tolerance for jacket runout. Sierrora keeps 'Standards' downstairs on the shelves by the test firing tunnel. If they get complaints about about a bullet, or have reason to question a test barrel, they load a few up out of the standards box to see what happens. These standards bullets were made on jackets with no runout. Not all Sierrora bullets get made on jackets to the same standard.
The best way to insure consistent quality is to buy from a custom bullet maker who will not allow jackets with significant runout. Guys like Guy Chism and Jimmy Knox will send jackets back to J4 if the quality and consistent wall thickness standards are not met. The big guys just build bullets on them. That does not mean that Sierrora has not made some great bullets, they have, and guys that get a good lot of them never forget it. The truth is you get a more accurate product batch after batch with the guys that set their quality standards higher. Jimmy Knox or Berger would be a good place to start.

7, That's all I wanted to know, what you guys are getting with the above mentioned bullets, I'm in the habit of calling bullet manufactures and asking what their accuracy standards are for the particular bullet I'm using and finding that Hornady and Berger have the highest standards yet Sierra has been the most accurate, although I haven't been seating the Hornadys as close to the lands as they seem to prefer but will do next time I load them, will find out this weekend when son shoots his 22-250 with 55gr. V-Max and 53gr match bullets .004 off the lands, I'll be tickled pink if he gets less than 1/2 moa with a bullet that has an accuracy standard of .250".
