What does "Match Grade" mean?

[Steyrlp10]

Regardless of whether the ammo is match grade or not, if your gun likes it without feeding problems and the price isn't a huge issue with you, then life is good

Imagine "blueprinting" for engines, that's what "match grade" is to firearms

Tighter tolerances on size and weight? If all the bullets have the same weight and closer resistance the same amount of powder should give a more consistent path.

Yes, they do have tighter tolerances on size and weight. Try pulling a part 2 boxes of wwb (first with a mic measure them, to see how closely they are seated in length), then weigh EVERY bullet, weigh each charge of powder. Their are going to be bullets that are +/- 2grs probably, the powder, not sure.

My match rifle rounds I load. I dont weigh the bullets (smk are all tight enough tolerances). I do weigh every powder charge to .01gr and seat every bullet to .001". And I am not even anal about it.
