Was shooting the SP101 .32h&r this morning with a box of Federal 100gr JHP that have been on the shelf for 10-12 years.
Fired a few cylinders of various handloads and Win factory ammo with no issues. Went in the house for 10-15 minutes to grab a coke out of the fridge. Temp was mid 90's. Gun was luke warm to the touch but not hot and was not left in the sun.
Loaded a fresh cylinder from the "new" box of Fed 100JHP and fired five rounds. Felt completely normal recoil wise. Went to unload and the cases were stuck. Took the gun in the house and after an hour tried to unload the spent cases. They were stuck so solidly I needed a brass punch and mallet to extract them.
On inspection the gun appears normal and the brass appears normal. Chambers are clean, no carbon ring. Primers were flat but not what I would consider to be flow. Just normal magnum loads.
Went back out side and fired a few more Win factory loads and had no issues.
Then tried another box from the exact same lot number of the Fed ammo. Fired 1 round, everything normal. Fired 4 more, normal. Fired 5 more, normal. Then went back to the original box of Federals that were sticky. Fired 1 round and I couldn't extract the case with the extractor star, and it took serious pressure with a cleaning rod to get it out.
So I think i can say it is not the gun.
Then took the "not sticky" box of federals and the sticky box and mic'd the ammo and pulled the bullets on a few rounds to weigh the charges. The charges appear the same at 2.9grs of some type of ball powder. Everything seems in spec.
Finally tried the sticky ammo in the .327mag blackhawk and it was sticky there too. Needed a cleaning rod to firmly push out the cases.
Any ideas? At this point I will shelf that ammo or pull it down and discard it. Not going to shoot any more of it. Just would like to figure out the cause.
