Are you getting shallow primer hits? First thing Id check is that the FP channel is clean and the pin is moving freely.
Also look very closely at the tip to see if it is peened or snapped off.
The Wolverine has always been rare, I doubt youll be able to find specs for the pin or a spare part if necessary....
As far as feeding and ejection- .22 autos are notoriously finicky with regard to ammunition. You will often need to try several brands to find one a particular pistol likes- hollow point, round nose, truncated cone, high-velocity, standard velocity.
Even after all that- and with a clean, lubricated gun- dont be surprised if it still jams once in a while.
Now, with regards to the Whitney in particular, and as original examples are so scarce, I would be (pleasantly) surprised if any fellow members have one they shoot regularly enough to comment on their reliability, but heres hoping!
They were neat guns that went through several generations in an attempt to make them profitable sellers, but the ray-gun styling and company mismanagement doomed them too soon.
I had the chance to buy a NIB nickel plated Wolverine once and always kicked myself for walking away.....
