Hey everyone, new here! I'm looking for some of you experienced guy's knowledge.
If I were to weigh factory loaded ammunition, and sort it all out by weight I am assuming that I'd have groups of more consistent groups and eliminate flyers.
The ammunition in question is 5.56.
I have weighed and sorted 40 rounds here are my results:
11.80 GRAMS x 2 rounds
11.82 GRAMS x 3 rounds
11.83 GRAMS x 4 rounds
11.84 GRAMS x 2 rounds
11.85 GRAMS x 17 rounds
11.86 GRAMS x 4 rounds
11.87 GRAMS x 1 rounds
11.88 GRAMS x 4 rounds
11.89 GRAMS x 3 rounds
Obviously for consistent groups I'm striving for 11.85 grams. I've come up with ROUGHLY - .01 GRAMS = 1.5 GRAINS.
So when we're talking about a variation of .04 grams from my base line of 11.85 grams, I'm wondering where will I start noticing the difference down range MOA.
It's a 5.56 round so its light, and there is not as much powder as the longer range cartridges out there, so I imagine 1.5 grains would be quite a big difference when we're discussing a precision group.
what should my tolerance be here. In a perfect world I have them all the exact same weight, I UNDERSTAND THERE ARE OTHER VARIABLES WITH WEIGHT- but speaking in generalized terms, we want uniformity.
I'm not about to measure the casings and the length, etc. Just looking for an answer regarding, assuming the variation in weight is powder. which most likely it is.
1.5 grains, how much is that effecting me down range at 100 yards. (I'm stretching to 500 with good groups, So looking for the precision perspective not, oh it's a .223 so anything sub 2 moa is good under 100 yards.).
will 1.5 grains of powder translate to .25 moa ? Will 6 grains translate to 3 moa ?
I'd really appreciate some help with this ! My own testing will be getting done in the next month and I'll update what I've found.
thanks so much.
