OCD ammo checklist

[Zeneffect]

Cases sorted by volume
Resized Cases within +-.0005
Cases trimmed chamfered, deburred on 3 way cutter to within +-.00025
Neck wall trued up with skim cut
Flash holes cleaned up
Case runout at neck and body sorted, all greater than .0005 rejected
Bullets weight sorted
Bullets bto sorted
Neolube inside case necks
Powder charge is within +-.01gr

Sort primers?
Uniform primer pocket?

Anything missing?

Only doing 50 for the shut up and shoot match next month so I can spend more time in prep and have a bigger lot to pick from. 20 more will be made for load verification. Going to run the 105gr sierra + power pro varmint load and see if I can push the precision harder though I may fall back to staball match as it just produced better groups with this powder, at the expense of almost 100fps... varmint sized targets so excess energy for knock down not needed, precision and accuracy required. Gonna run the uintah bolt ar15 just because I can, and it's just flat out set up to do exactly this kind of work.

No...I'd say you pretty much have it covered!

But it is CDO, alphabetical like it should be!

There are many things I question about drilling holes in powder, first and foremost is is this a joke?

Second, if you are removing 30% of interior mass without controlling outer dimensions, what is the point?

When you need to add 30% more to make up same weight, how does that fit in a case?

How does a kernel hold up after seating? I would imagine fractures etc....


In all, looks like either a joke or a scam to me. If 1 kernel weighs .006gr and you need 28+gr.... its better use of time trying to flap your arms really hard and fly.

Yep, it's a joke.

Which two of the above, in your experience, give the greatest result for time spent?

Figure 14 on page 13 has cured me from getting too wound up over charge weight precision/consistency. Too small of a sample size was usually the culprit!

LOL!!! that micro drilling is a total hoot!!!

I guess if it were me (not being ocd), seems as though you are deep into the area of "diminishing returns".
The amount of prep you show seems more in line with a perfectionist-competitor where shooting into the 0.3's is not good enough.
But then such a shooter would not be shooting grendel. It would be a $5k-$10K rig in a target rifle, for benchrest or such, 1000-1500 yd capable outfit.
So if you're going down this road, it is impressive, but too deep into diminishing return-territory for me.
I'm still the biggest variable in the shooting equation. If I could stay in the 0.7-0.5's each and every time, then maybe I might see what else I could do.

If I were to pick only 2. Powder weight and neolube. Powder to keep the es and sd as low as possible while staying in the accuracy sweet spot.

Neolube is a band-aid and a half and can make a crappy load shoot decent, and a decent load shoot awesome. Between keeping powder weight consistency tight and a more even seating force from the neolube (plus cold weld prevention) the group size will shrink the most. The rest give you fractions of fractions... but it all adds up. Given the low volume I am working with, it's worth doing.


.25 moa or better is needed for the games I'm playing so diminishing returns is fine so long as it's not costing excessive amounts of money.

Meplat uniforming... but plastic tip so... ???
