Yeah, I know,
I have used Cheddites for years, subbing them directly for Winchesters with no issues whatsoever. Today, however, an odd thing happened. i came into a brick of old Winchester 209s from Dad's stash (he passed away in January of this year). Ran some equally loaded hulls and decided to go run them across the chrono just for the heck of it. BPI says Ched primer, 17 grains Titewad under a PT 1205/Fiocchi H-27 wad and 1 oz payload should give 1200 fps in a Cheddite hull, in my case Challenger.. My bored 1 oz bar is throwing 30 grams (1.04 oz) so the resulting velocity of 1175-1185 is understandable. BUT, when I decided to use these orphan Winchesters up, I thankfully loaded just a handful to compare them, the identical recipe on 4 of 5 sample shells dropped to 920 fps, with one running 1180. WTF. These primers have got to be 40 years old, or more. Lot number of KLL166 on boxes, but I dunno how to check age, and would age have that much of an affect? They sounded way weaker too, but not exactly poofter sounds.
I really don't want to experiment with an increase in powder to get them up to 1180, especially with this one of five shell running normal. Concerns me that I might get a heater every once in a while. It's only 1000 primers, well, 990 +/- now, so tempted to toss them, but that is sacrilege in these hard to find times.
Anyone else ever have issues with aged primers?
