Just a quick comment about taking a couple of dry fires to start with.  That’s a reasonable plan for plinking and target shooting.  However it’s a deal breaker for hunting and pest control where you may be waiting an hour or more before taking a shot.

I don’t think it was mentioned in this thread but don’t worry about creep until you’ve adjusted the hammer strike to put the rifle on its velocity knee.  That is, dial up the hammer strike until the velocity no longer increases, then back it off to 95 – 97% of that max.  When adjusted in this manner, the gun is least sensitive to pressure variation (creep).

It is the same principle that allows an unregulated PCP to produce a narrow extreme spread over a wide pressure range.
