They did microgroove up til about 5 years ago, then supposedly went to deep cut. problem is the lazy twist rate they use on the .44 cal barrels. I wish it was 1:20 but its 1:32 which makes it marginal for 240 grainers at 1800 fps (.44 mag velocity) you can probably get away with 300 grainers with the .444 because it pushes em faster.

The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do. Fact of life: After Monday and Tuesday, even the calendar says WTF!
