I guess the pictures are being blocked here at work. I can't see the grains.
Patrick-
I'd weigh each grain and see if they are way off from each other or not. I flown many AMW loads that looked similar to those grains with no issue, but that's just me. I'd fly it as I have not had any problems in the past....

Seconded; a few bubbles and voids are normally found in AMW, Kosdon East, Kosdon loads. Nothing to worry about. I have NEVER seen a properly assembled AMW load fail....ever.

Thirded, saw these a lot in L1860 and L850 loads in the past. I think the defects here are bubbles that got cut in half.
Sidebar: my phone corrected "got" to G&T. It knows who you are, Eric!

That is fantastically awesome! I do believe your name came up in the roll call for the May QCRS launch....I will bring along a G based concoction that will blow your mind! Ok, now I'm salivating.
Back on track here; Patrick, I'll weigh the L1300 grains I have here and report back.

Cool thanks Eric!
Wednesday Weigh In:
Average grain mass: 218.8g
Lightest grain mass: 217.1g
Heaviest grain mass: 219.9g
Total mass of grains: 1312.6g
Percent of grains with visible voids on one or both ends: 100

Hahahahahaha when I first saw the thread title, I thought "some noob is confused about the grain cores" but found something more interesting instead.
I agree with jpummil's assessment, though: it looks crushed in and not drilled, and not like a bubble either.
When in reality, a separate noob who's clearly never made or cut grains before was the one who was confused and unaware that that's exactly what a bubble in a grain looks like when cut down the middle.
Your permeating condescension because of your HMC AeroEng degree may be warranted in some areas, but not all.
I was able to weigh the grains tonight with my not so accurate 500g food scale(non digital). I got 1334g as the total. The scale only has 10g lines so I had to rough guess any weights that were in between. There is a 5g difference between the lightest and heaviest grain. I understand the total is more than the motor should weigh(probably due to scale inaccuracy) so the only real option is to quit worrying and burn it next weekend
Thanks for the help and I learned something new.
