Bumping this up since I had some time to kill, and wanted to dummy check myself after my last outing.
I weighed my remaining (85 pieces) 110 Atip Seconds on a fx120i. ES from 109.82 to 110.32 gn. Most between 109-110.5, normalish distro.
Base to Ogive (with SAC comparator) .598 to .604 with outliers up to .607. Evenly distributed in 2k buckets between 598 and 604.
Overall lengths between 1.326 to 1.335, evenly spread.
No obvious correlation with lengths or weights. Not sure how these numbers stack up to non-seconds. No deformed tips or big jacket wrinkles/deformations in my 100ct box, although there are some small jacket dents that look like jostling with other bullets. NBD in my mind. I have some 153s I haven't opened I'll probably play with later this week.
