It’s from the first production run Ruger did for Accusport and it was a basket case when I got it.
That's a shame you had issues with it right out of the box, but now it's probably even more special since you personalized it. I forgot to ask, in the pictures two of the targets have 5 holes each, but the 3rd only has 8 holes...where's the other 2 ?!?

(I always shoot in groups of five too.)
I’ve been shooting USPSA for a while now and I discovered the same thing with Remington cases.
That Remington brass is probably the oldest 45ACP brass I own...I'll never buy nickel plated brass again though.
Did you try, loading the cylinder full, shoot all but the last round, remove said round and measure the OAL to see if it had grown any under the recoil forces?
Yes & no. I believe I shot a full load, of five, with the "problem load", since I had made 25, but I can't say for sure if I checked them. The one load I definitely recall checking, in this gun, was a test batch of 45 Colt +Ps, 200 gr. Hornady XTP .451", CCI 300 & 20.5gr. of 2400 @ ~1300fps/750ME and 200gr. cast LSWC .452", CCI 300 & 19.0gr. of 2400 @ ~1280fps/726ME. Both of these did not have cannelures (45ACP bullets) & were taper crimped over the ogive or shoulder. I wanted to see how they performed & if the recoil would unseat the bullets. They both shot fine & the last bullet hadn't moved, which I was happy with. After I got this gun I spent most of my time trying different combinations of bullet weights, in small test lots, & experimented with H110, AA#9, & Lil'Gun. After "the squib" troubles this gun got pushed aside when I found a 325NG & started loading up ACP, Auto Rim & Super combinations for it. I need to get back to the 454 & continue work on my "Big Bang Theory".
