Model 64 misfire issues

I bought my kids Savage .22s for Christmas this year. # model 64s and a model 64fl. The 3 64s fire perfectly, however the 64fl misfires almost every other round. I load the clip and chamber the first round, pull the trigger and it fires, ejects, and chambers the next round. Pull the trigger for the second shot and only get a click. Manually eject the round and chamber the next and it will do the same process. Upon inspection of misfired rounds I noticed the firing pin mark was barely visible. Any suggestions on the cause.

Sounds like firing pin is not moving freely in bolt. Remove bolt, clean channel and firing pin. If firing pin is still not moving freely, lightly sandpaper until it does. After considerable firing it may need to be cleaned again. This was the case on my 64 FV-SR.

CLP and welcome....

Thank you. I will try this and post the outcome.
