I've been shooting this ammo a bit but have suddenly, as in the past week, started having problems with it not ejecting. The rifle checked out fine except for a small amount of carbon build up in the chamber. I tried a few other types of ammo, TAP, Aussy, some unknown steel core surplus from a buddy, and they all worked without issue.
Looking at the case mouth on the SA it is getting blown out a bit larger than the other ammo
and causing it to "stick" just enough to prevent ejection. You can see where the extractor is
stripping material off the rim in its attempt to pull it out. Manually extracting the case using
a rod or small flatblade is very easy.
Hopefully a thorough cleaning will make my rifle happy with this ammo again since I have approx 1,000 rounds of it at my house.
