Hornady lock and load 50bmg press kit - Hornady Lock-N-Load .50 BMG Single Stage Press Kit

It's a superbly constructed press and comes with the dies needed to begin reloading.
The feature that makes this stand out is the lock and load set up of the dies and the clearance height for placing and removing the finished round. Also, once you have set the proper height you can change out the dies and put them back in and still be all setup.
The press can also do other calibers, and in my case the .338 Lapua Mag.
