No, I don't have one, but I have read up on them and spoke to quite a few experienced gun smiths.
The P-14 action seems to suffer from a similar fate as the WWII Mauser action. It was made during the 1930's and 1940's rush for military use. It means that some are simply great, and some are less than great.
They came to fame during the 1960's to 1980's (?) when few other actions were available or affordable, and did a great job of the actions expected of them.
However, with modern technology there are new challenges to the old war horses. Production costs are low for new actions, and it is expensive to work on an old action. In SA, barrel changes are cumbersome, which makes it even more attractive to simply buy a new rifle.
