I have had a 444, and still have a 45-70 and a 375, for a first timer I recommend the 45-70 for the reasons stated here. plenty of ammo choices from mild to wild and the original 405 grain Remington will take any deer that walks the earth. The other two will try your patience ( and pocket book) getting reloading stuff and factory ammo.
Ammo for 444 and reloading components ain't hard to find. Hornady Superformance 265 $26.00 a box found using ammoseek.com. Hornady and the mucho great Starline brass is easy to find. Bullets are everywhere.
