To my knowledge the largest, as in physical size, and caliber is the South African NTW-20. This is a sniper rifle but more specific, an anti-material rifle.
The NTW-20 comes in two variants, a 20mm and a 14.7mm version. Both of which are much larger than the 12.7mm (.50) BMG round used in the Barrett M107 and Intervention.
The NTW has an overall length of 2015mm (6.6 ft) in the 14.7mm trim, and an overall length of 1795mm (5.8 ft) in the 20mm version. A very large gun indeed, the gun is usually operated as a two man team.
Oddly enough this gun was also what the Halo sniper rifle was modeled after.
