No, it still has the original (felt) mile-long creep until the shot breaks somewhen. The only alteration has been to take off the PU scope and mounting*, replace with a modern scope on a new mounting, discover that the result wasn't so hot, and ruefully put the PU+mounting back again! It is one of those rare rifles where I am afraid that changing anything will make it worse, so the urge to "improve" must be resisted.
*whereby I was very careful to loosen only one of the vertical clamping screws on the mounting - the bottom one - in order to be able to replace the PU without losing the height setting.
