Miss. Code § 13-5-10
The jury commission for each county shall maintain a jury wheel into which the commission shall place the names or identifying numbers of prospective jurors taken from the master list. If the total number of prospective jurors on the master list is one thousand (1,000) or less, the names or identifying numbers of all of them shall be placed in the jury wheel. In all other cases, the number of prospective jurors to be placed in the jury wheel shall be one thousand (1,000) plus not less than one percent (1%) of the total number of names on the master list. From time to time a larger or additional number may be determined by the jury commission or ordered by the court to be placed in the jury wheel. In April of each year, beginning in 1976, the wheel shall be emptied and refilled as prescribed in this chapter.
