I bought/installed the 500mm .22cal barrel on my MKII Crown and was wondering what the twist rate is on this one. Thanks in advance.
FX Crown MKII .22cal twist rate

No one can say for sure. I have seen multiple posts where the liner isnt the correct twist. It should be 1:24 if its not the heavy liner. Pull the shroud and see what its marked as.

There is a large variation of liners, with different twist rates also amount of choke. The naming is confusing lately.
I have four liners in .25 for example (and two in .22), two Superiors (x600 and x700 lengths) probably from different - over a year time stamps, and the choke amount is different I measured with push through slugs. I didn't investigated deeper but assuming these were different PN's.
Pull out the liner and best to measure the TR, I would suggest don't try to memorize the names but look up the PN (part numbers).
