Appellant Michael Caulfield appeals the district court’s calculation of the amount of his sentence reduction pursuant to 18 U.S.C. § 3582(c)(2). Caulfield was convicted of conspiracy to possess with intent to distribute more than 5 grams but less than 50 grams of cocaine base and more than 500 grams but less than 5 kilograms of cocaine hydrochloride (Count 1), distribution of more than 5 grams but less than 50 grams of crack cocaine (Count 2), and using a communication facility to facilitate the commission of a drug trafficking crime (Count 3). The district court sentenced Caulfield to 275 months in prison on Count One and Count Two and 48 months on Count Three, to be served concurrently. Caulfield filed a motion to reduce his sentence pursuant to § 3582(c)(2), based on the United States Sentencing Commission’s retroactive amendment to the base offense levels for crack cocaine offenses. The district court granted the motion and sentenced him to 250 months in prison. Caulfield filed a notice of appeal, but later filed a motion to dismiss the appeal, which we granted. Caulfield then filed a motion for reconsideration in the district court, arguing that the court had erred by applying an amendment to the Sentencing Guidelines that was not adopted until after he initially moved for a reduction of his sentence. He also contended that his continued good behavior in prison warranted a further reduction. The district court rejected Caulfield’s argument that it had relied on the incorrect Guidelines amendment, but it granted him a further *283 reduction to 235 months based on his good behavior. Caulfield appeals. For the reasons set forth herein, we affirm the district court’s ruling.
“ ‘[A] judgment of conviction that includes [a sentence of imprisonment] constitutes a final judgment’ and may not be modified by a district court except in limited circumstances.”
Dillon v. United States,
- U.S. -,
Caulfield argues that he is one of the handful of defendants who fared better under Amendment 706 than under Amendment 715, and that, because Amendment 706 was the amendment in effect at the time he brought his motion for a sentencing reduction, he is entitled to be sentenced under that amendment. The Government responds that the district court correctly applied Amendment 715 and that, in any event, it did not abuse its discretion in declining to grant a more substantial reduction. Caulfield bases his argument at least in part on the
Ex Post Facto
Clause. U.S. Const., art. I, § 9;
see United States v. Kimler,
In light of the above, the judgment of the district court is AFFIRMED.
