| Is this needed? I don't for my .223 plinking loads, but I do for my precision .308 loads. I started measuring my brass and bullets so they all had the same col, but I don't think it made a difference. Should I start weighing each bullet? Im just trying to squeeze as much potential out of my loads as I can. |
| Based of the recommendation of another reloader, I have stated weighing all my Hornady 55g FMJBT. I they can vary a lot. I sort them by true 55g, over 55g and under 55g. I use only the true 55g for my ladder test when working up a load. The rest I use for plinking rounds. It may not make that much of a difference, but its gives me another excuse to spent some quality time in the reload room. |
| For cheaper FMJ / surplus bullets it might make a difference. I use M80 style surplus bullets in .308 they are decent quality, segregating them by weight makes a difference for more accurate shooting. My Sierra's MK and Hornady match bullets are close enough no need to weigh them. |

Try this. Measure a bunch to figure out what your spread looks like and pick 5 at the high end and 5 at the low end. Make 5 of each load, load them up and shoot them at the target. Do you have 1 group or 2 groups? If you can identify 2 groups, I'd consider continuing to sort, But once you compare the actual differences to point of impact, I don't think you'll bother again. |
| Depends on what you want. If you are shooting benchrest and want the tightest groups you can get, you should weigh and measure everything for uniformity. If you are looking for just a good MOA load for shooting steel, then just make sure your headstamps match, the brass is trimmed consistently and that you get a consistent OAL to the ogive as the tips of the bullets can give different COALs. |

It's a waste of time but a necessary step for most new reloaders to get past.
Your long range .308 Win ammunition will benefit more from uniformed meplats, if you can suffer the loss of BC. But that can be recovered by pointing up the bullets. I bought some seconds from Sierra this spring that were remarkably clean, much better than any batch I've gotten before. While sorting through them to find any odd bullets I weighed a few; the weights varied +/- 0.5 grains. New Sierra green box bullets weigh +/- 0.3 grains. |
