I know we have touched on this .
A recent fun shoot "1925 rendezvous ala' steampunk" gathering I found the insidious bullet growth . I found that 9mm loaded some 7-8 yr ago had swollen enough that they just won't chamber in the HP clone . This is 200+ 358-124 TLTC they were seated fairly deep with only about half of the top/front band out of the case . I might be able to save them as they were loaded light . I might be able to bump seat and crimp .
45 ACP . The cases have moved also . I had loaded about 350 45 ACP when I scored a 1917 Smith . I had full length sized it all and done a percentage check fit and sized to fit the throats . I found that some of the bullets just didn't shoot well so those were segregated out for the High Point carbine which does .
Like the 9 I loaded this about 6-7 yr ago . 4 yr ago I ran them though a gutted FCD because I had a bunch that were hitting on the head , well below Glockage , and they were fine in both the Smith and Ruger BlackHawk . Now I have .453 front bands at .4545 and they won't go in the Smith . As I don't have to headspace on the mouth and I have a taper crimp I may be able to save these if I can choke the front band down ......or I might just go unload them in the Hi P .
The last victim was a 6.8SPC I recently barreled a Savage in . Having adopted the size for the tightest chamber where more than one resides I've done well in the past and with this one . Same deal here , ammo loaded 6ish yr ago . A percentage check in 2 gas guns says all's well there with 1% hitting the lands enough the mark but not stick . In the bolt had typical firm cam of "not my brass" , then a nope resulting in a stuck bullet . The last round was so big in the bolt gun that a pound cast isn't needed for nose and band dia ....... It's all good I have 3 HS , FC for the gas guns , RP for the 7×6.8 Carcano and I guess the bolt gun will have to be happy with S&B .
These bullets were from 3 batches one alloy lot , it's possible I missed a fat nose or several during my cull , lube , and checking . Lengths were regular , I'm left with growth ........
Water dropped WW and tamper seals 75/25 for the rifle . At 6 months they were 18+ just a little harder than the as cast that was just shy enough to not pencil 18 BHN . They're 24 now , to hard for my intention , but they shoot well high stepping in the gas gun . .279-124 NOE .
I used the tamper seals in all the above . I suppose I'll run jacket and plated cores for the next run of likely long term study . The tamper seals behaved like 20-1 and picked up some copper , but there must be something else in them that is messing with the long term more than the "normal" growth .
I don't know if it's note worthy or not or if it's worth wandering around in there probably aren't a lot of us around that have loaded cast sitting around for 6,7,8 yr .......
Data is data though right ?
