Launched in 2002, the .17 HMR (which is short for Hornady Magnum Rimfire) was designed by Hornady in collaboration with Marlin and Ruger. The goal was to create a rimfire round with a longer reach ...

17 HMR. With their miniscule bullet diameters ... cartridge maker and firearms giants Marlin and Sturm Ruger — I didn’t join the ranks of the .17-caliber clan until 2009.

Putting a round like this through a gun like the Ruger M77/17 was an amazing experience, and I highly recommend anybody who likes .17 HMR give it a shot as they will certainly enjoy it.
