Micro Grove? Lots of shallow rifling...
The Marlins I have, all but one have Ballard barrels. When I looked at the rifling the first time I thought I had made a mistake and gotten a microgroove. Then I ask on line and found out it was their Ballard rifling. Ballards have six groove and microgrooves have twelve. Both Ballard and microgroove 44 magnums have 1/38 twist rates. The microgroove barrels have microgroove roll marked on the barrel. Ballards don't say microgroove, but don't say Ballard either.
