I picked the used one up very reasonably and it should be to me in a week.I'm curious if anybody knows the twist rate and groove diameter of the Walther polygonal barrels they use on these.
If the barrel is the LW non choked poly then it is a 1:17 I believe......amazing barrels! They shoot pellets and slugs very accurately. Mine is also an HMx LRT 22. Congratulations and enjoy shooting it .
