The 444 Marlin is one of my favorite rounds. I have a Handi Rifle and a Marlin 336 lever in 444 Marlin. Reloading does save you some money but be prepared to use a lot of powder if you want to shoot a lot. I use 41gr of IMR4198 with a 300gr bullet. So a pound of powder will only make about 170 rounds.

To preserve liberty, it is essential that the whole body of people always possess arms, and be taught alike, especially when young, how to use them... -- Richard Henry Lee, 1787
