Sportster .22 WinMag barrel. What type of rifling does yours have?

[JimG]

My Sportster .22WinMag has Marlin's Microgroove rifling. Looks exactly like any Marlin .22lr barrel. Just curious if this is standard or if H-R had runs of the Microgroove and runs of standard type rifling for the .22WinMags? I've seen Sportsters chambered in .22lr that had regular rifling in them as opposed to the Microgroove type. Actually I've never seen a .22lr Sportster with Microgroove rifling although my Versa-Pack .22lr barrel has the Microgroove rifling.

They've used both, just depends on what they're doing at the time, both my 22Lr and 22Mag are standard button rifled, lots of Versa-Pack MG barrels out there like the sectioned pic of one below.

Anyone have any opinions as to which .22WinMag barrel would generally be more accurate? Micro or button rifled?

IMHO, its not the rifling type, but the quality of the bore ;uniformity, smoothness and the right dia. for the projectile/caliber that makes an accurate barrel.
