After nearly 40 years of shooting I had a firearms first; two actually. The first was a hang fire of about one second which made me miss a varmint. Second was a squib (main charge failure ) that pushed the bullet about a half inch down the barrel. Thankfully the bullet's location did not allow another round to be chambered. There is probably not enough giddy up in a 17 to be a hazard but it wouldn't have done the Marlin any good. I had to use a cleaning rod to force the bullet back down the barrel. Both of these were from a fairly old box of Hornady 17 HMR. Didn't do my cleaning jag any good forcing the bullet back out. This is an older box of 17 grain lot code C08L02. That box is getting trashed.
