The muzzle velocity of an AR-15 can vary depending on the specific ammunition used, but it typically ranges from about 2,700 to 3,200 feet per second (fps). Standard .223 Remington or 5.56x45mm NATO rounds commonly fired from an AR-15 generally have velocities around 3,000 fps. Factors such as barrel length and bullet weight can influence the exact muzzle velocity.
The AR-15 rifle has a fire rate of 800 rounds per minuteand a muzzle velocity of 3,200 feet per second.
Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.
the muzzle velocity on the 40gn vmax is 2200fps
It depends entirely on the muzzle velocity of the weapon you are using. The higher the muzzle velocity the farther the projectile will travel.

The L1A1 SLR used by the British military is in caliber 7.62 NATO, and has a muzzle velocity of about 2800 fps.
The M4A1 version of the M16 rifle has a muzzle velocity of about 2900 feet per second, firing the 5.56mm cartridge.
Muzzle velocity of the SS-109 cartridge is about 3100 feet per second.
@ 1000 fps
Muzzle velocity is a function of type and quantity of powder, as well as the mass of the projectile and the length of barrel. All of these factors being equal except the bullet sizes in the question, probably the 357 with the lesser mass would have the higher muzzle velocity.
