The .17 Hornady Mach 2, or .17 HM2, is a rimfirecartridge introduced in 2004 by the ammunition manufacturer Hornady, following the successful launch in 2002 of the .17 HMR. The .17 HM2 is based on the .22 Long Rifle 'Stinger' case, necked down to .17 caliber (4.5 mm) and using a bullet weighing less than half the weight of a typical .22 Long Rifle bullet.

Performance[edit]

The weight of the bullet is a key part of achieving the very high velocity for a rimfire round. It weighs only 17 grains (1.10 g) vs 30-40 grains (1.94-2.59 g) of a typical .22 LR bullet.[2] The .17 HM2 may or may not live up to its 'Mach 2' name, depending on geographic location and conditions, with velocities out of a rifle of 2,100 ft/s (640 m/s).[3] The velocity is nearly double that of a standard .22 LR, which results in a much flatter trajectory out to its 175-yard (160 m) effective range.[4]

Converting rifles[edit]

Left: .17HM2, right: .22 LR

Since the .17 HM2 is based on the .22 LR, converting most bolt action firearms chambered in .22 LR to .17 HM2 requires only a barrel change. The higher pressure makes conversion of semi-automatic firearms more difficult, as virtually all are blowback designs that are sensitive to pressure changes. Conversion kits have appeared, and they replace the factory bolt or bolt handle with a heavier one to increase the bolt mass and compensate for the higher pressure.[4]

• Define custom controls to move and zoom, move to other display, center, resize, and more
• Chain custom controls together to execute complex window management tasks
• Save window layouts to easily recreate a desired window arrangement at any time
• Automatically activate saved window layouts on changes in monitor layout, as in when you disconnect from your work display and then open your laptop at home
• Use keyboard mode to do all of this, and more, without ever touching a mouse

Moom 3.2.6 has been released with a few bug fixes for snap-related actions. Users had reported some issues with snapping when working with zoomed displays and when customizing toolbars, and some reported decreased responsiveness in certain apps. We have addressed all of these issues in Moom 3.2.6
