Long Range Naval Guns
Just as a point of interest to supplement the Zumwalt ammunition post, had the Navy not opted to go down the path of the Zumwalt and AGS, we might well have attained our goal of long range bombardment capability with conventional naval guns by using sub-caliber rounds. Here’s some examples listed on the NavWeaps site (1).
Improved HC Mark 147? (Planned)
During the battleship reactivations during the 1980s, the Navy developed a new HC [High Capacity] design that was the same length as the AP [Armor Piercing] Mark 8 (4.5 calibers) and weighed 2,240 lbs. (1,015 kg). Several of these were test-fired from USS Iowa and at Dahlgren, achieving ranges over 51,000 yards (46,600 m) with a new gun muzzle velocity of 2,825 fps (861 mps).

Range = 51,000 yds = 29 miles
HE-ER Mark 148 (Planned)
13.65 in (34.7 cm) diameter, extended-range (ER), sub-caliber projectile with sabot. Length was approximately 72 in (183 cm). Projectile was to be ET-fuzed with a payload of about 300 M48 grenade submunitions. Experiments with this projectile were conducted during the 1980s, but development was cancelled in FY91 when the battleships were decommissioned. Projectile weight without the sabot was about 1,300 lbs. (590 kg) and range was to be in excess of 70,000 yards (64,000 m) at a muzzle velocity of 3,600 fps (1,097 mps).

Range = 70,000+ yds = 40+ miles
HE-ER Mark ? (Planned)
Advanced Gun Weapon Systems Technology Program 16/11-Inch Long Range GPS Concept with Sabot. Another sub-caliber projectile with sabot, this one 11 inches (28 cm) in diameter. This project was also cancelled about FY91.
Range: 100 nm
Launch Weight: 650 lbs. (295 kg)
Fly Away Weight: 525 lbs. (238 kg)
Launch Length: 69 in (175 cm)
Payload: 248 M46 Submunitions, total weight of 175.2 lbs. (79.5 kg)
Guidance Modes: GPS and INS

On a relative basis, these would have been very cheap to develop and yet the Navy refuses to look to conventional weapons, instead always preferring to go down the path of new, highly risky technology and astronomical costs.
