what is the acceptable variance in bullets weights, for hunting pursuits? never thought about it much, then started checking and was surprised, not in a good way.
hold on Newt, we got a runaway

I've tested some Sierra matchking bullets a long time ago at 1K yards. I took 190 SMK in my 300 WM and weight sorted about 100 bullets. I took the heaviest and lightest, and loaded them up with all the same load that shot good in my rifle. I shot them at 1K yards, and I could not tell the difference in elevation between the 2 groups. The weight variation was less than 1 grain. Some may be able to tell, but at that time, I couldn't tell. For hunting and out of a hunting rifle in field conditions, the weight variation is a non-existent.

Chad's right.
Besides, if you're going to be hunting, you probably aren't going to be in perfect weather conditions with a perfectly stable rest to shoot from, a slow heart rate, and no angle to your target that you need to account for. All of those things will make a much bigger difference in your group sizes at a distance than bullet-to-bullet weight variation.
Benchrest shooters do it, but pretty much nobody else does because the .1" difference you'll see will be more than overshadowed by the factors listed above.

Are you shooting at 0-250 yards or 500-800 yards or 800-1200 yards? Really, jacketed bullets just don't vary enough to matter in any realistic hunting conditions I have ever seen. Your question is more a concern over a factor that is so much more a theoretical issue for long-range competition than hunting.

I'd worry about the brass weight more than the bullet.

I'd worry about the brass weight more than the bullet. Yes. The main thing I pay attention to is the powder charge weight. That's a big one. The next big one would be the case weight (or case volume, specifically). That's more of a factor than the varying bullet weight.

I will second the above. Powder charge (and the pressure created) combined with case volume are going to be your 2 big hitters for precision. It's the control of that pressure spike and making it consistent that will wind up making tight groups downrange (eliminating the jerk behind the trigger). Following that, the next big gain you will see is from uniform neck tension, ensuring the rounds are let go from the case "at the same time" relative to that pressure spike.
