A 5 gram bullet traveling in 20 0C air at 300 m/s strikes a flat steel plate and stops. What is the final temperature of the lead bullet?(Assume all heat is retained by the bullet. The melting point of lead is 327 0C. The specific heat of lead is 0.122J/g-0C. The heat of fusion of lead is 24.7 J/g.)

The question is lacking crucial data required to reach a conclusion. How many grains of powder are contained in the bullet. (i.e. the % of total weight, and the weight of the primer, & jacket?). Some bullets, (like 22 cal.) are super rounds because of the extra ballistic powder.
