Around 300 yards.
If you mean the US military cal 30 M1 Carbine, the effective range is about 300 yards. Other weapons will have different ranges (different calibers)
30 caliber = .308 of an inch = 7.62mm
The Universal company did make a civilian version of the M1 Carbine. Not all of the Universals use the same parts as the military issue M1 carbine. Please note this is caliber .30 Carbine, and not the 30-06 caliber of the M1 Garand rifle.
About 300 meters, depending on the rifle, sights, ammo, and skill of the shooter.
You can only use .30 carbine ammo or the European designation 7.62X33 ammo
what is a m1 carbine worth
your question is not specific enough, .30 cal carbine can be anything, as for 1944 can also mean a very wide range of firearms. for the two I know of: M1 Carbine, .30 carbine caliber, semiautomatic carbine Inland - around $800 Mosin Nagant M44 carbine, manuf 1944 in very good condition (like if you bought "new" from a store) around $90. there are hundreds of ".30 cal carbine" that are also manufactured in "1944".
Depends on who made it, how old it is, parts orginality, history, etc.. It could range from 100-1500 USD.
