Greetings,(posted 8649 days ago)Indeed, if 5L is lasting 9 months, one is probably not shooting enough. The 5L I had sitting around was for testing purposes only; it actually lasted a year before any density changes were noted. The other noteworthy caveat with XTOL is discard it if any of the packaged powder is caked. Better yet, don't discard it, get a refund.
