Sorting Ammo Question

[Jersey Devil]

Is there a a benefit to sorting (and clipping) ammo of the same year or lot?

For example, like many people I have a good bit of Greek HXP. Much of it came from the CMP and there's quite a few different years. Is it advisable to sort only the same year ammo and clip only that ammo up?

Currently I have quite a smorgasbord of ammo clipped up all together.

Thanks!!

If you have the time, why not? But, if you have a mix of old and new en blocs it's a good idea to separate at least into pre and post '73 production, as they changed the extractor groove dim's that year, and the en blocs as well. Early cases have narrower grooves, and if installed in a later enbloc will spread it apart a wee bit. Later rounds in early en bloc ok, later in later ok, early in later no bueno...

At least that's with my untrained eye...

I have all my HXP sorted by years. There is no guarantee that the ammo from a particular year is all from the same batch.
However, it does give you a chance to inspect each round for corrosion or damage.

JD it cant hurt, and any odds one or strays can be used as fouler's and warm up rounds.

I never bought any of CMPS mixed floor sweepings before but I have sorted boxed and clipped HXP according to weight.
You would be amazed the difference in weight of rds. I wold cull anything under 397 and over 400 gr and use those for sighters. Then take these sorted rds and roll on a flat surface and look for bullet runout. Any that have a bad seated bullet, set hose aside for sighters.
The leftover ammo is very accurate and if you now have any flyers it from the shooter, not the ammo. It makes a huge differnce

I think so, I would say if it is match grade for sure, but by the same line of reasoning any ammo that performs nearly the same, i.e., from same lots should be grouped together. Some lots and years are slightly different than others, using different powder charges or bullet weights which will change the POI of the bullet. Military snipers I have known check the zero with a new lot of the same bullet. I don't see a downside to it.
