Been using mine for many years......
Original chamber was 20 BR...thus the 9 twist/3 groove barrel (55 Bergers)
Sent barrel back to Pac Nor to rechamber to 20-222...good choice
As shown in pic...dedicated portable table p/dog gun....18# as shown
Prob my favorite of the 20 cal's...wore out a 20 Practical (20-223)
Currently waiting for new P-N 20 Practical tube..10 twist/3 groove
I use Savage Target actions....easy to swap & set up your self...
Yes.....my other 20 is a 20 Vartarg (20 Fireball) I set up in 2007
