In 1975 the petitioner was convicted of assault with intent to murder, G. L. c. 265, § 15; assault and battery by means of a dangerous weapon, G. L. c. 265, § 15A; and unlawful possession of a machine gun, G. L. c. 269, § 10(c). He appealed under G. L. c. 278, §§ 33A-33G. We took the defendant’s appeal for direct review and affirmed his convictions.
Commonwealth
v.
Cepulonis,
We conclude that a sentence of forty to fifty years for a violation of G. L. c. 269, § 10(c), does not constitute cruel and unusual punishment. Further, we hold that the petitioner was neither subjected to double jeopardy nor was he denied effective assistance of counsel. Accordingly, we affirm the judgments.
The facts are set out in our earlier opinion.
Commonwealth
v.
Cepulonis,
A.
Cruel and unusual punishment.
This court has recognized that it is possible that imprisonment for a long term of years might be so disproportionate to the offense as to constitute cruel and unusual punishment.

McDonald
v.
*497
Commonwealth,
The burden is on a defendant to prove such disproportion because the Legislature is given broad discretion in determining the punishment for a given offense.
Commonwealth
v.
O’Neal,
The first prong of the disproportionality test requires inquiry into the “nature of the offense and the offender in light of the degree of harm to society.”
Commonwealth
v.
Jackson, supra. Opinion of the Justices,
The second prong of the disproportionality analysis involves a comparison between the sentence imposed here and punishments prescribed for the commission of more serious crimes in the Commonwealth. See
Opinion of the Justices,
The final prong this court examines in the disproportionality analysis is a comparison of the challenged penalty with the penalties prescribed for the same offense in other jurisdictions. Initially, we recognize that a disparity between this Commonwealth and other States may indicate no “more than different exercises of legislative judgment,” rather than “a difference between unrestrained power and that which is exercised under the spirit of constitutional limitations formed to establish justice.”
Commonwealth
v.
Jackson, supra
at 914, quoting from
Weems
v.
United States,
The petitioner argues, further, that a sentence of forty to fifty years is excessive and unconstitutional because it “makes no measurable contribution to acceptable goals of punishment and hence is nothing more than the purposeless and needless imposition of pain and suffering.”
Coker
v.
Georgia,
While there may be serious debate as to the “effectiveness of harsh penalties in reducing crime,” Commonwealth v. Jackson, supra at 913, the Legislature has not unconstitutionally exceeded its prerogative by authorizing the sentence the petitioner received in this case. Such a term in State prison, furthermore, extends the petitioner’s incapacitation and exacts a large measure of retribution. Finally, a legislative judgment that a severe sentence for unlawful possession of a machine gun is needed to reform the perpetrator of such a crime is not irrational. The petitioner has not met his burden of showing that his sentence is unreasonable.
*500 B. Double jeopardy. Cepulonis contends that the offense of illegal possession of a machine gun is a lesser included offense of assault and battery by means of a dangerous weapon. 3 He concludes, as a consequence, that punishing him for both crimes is a violation of the double jeopardy clause of the Fifth Amendment to the United States Constitution and of the common law prohibition of duplicitous convictions. 4
The Commonwealth contends that a fair application of the test derived from
Morey
v.
Commonwealth,
The test for whether two statutory offenses may give rise to two convictions arising from a single incident is whether each crime “requires proof of an additional fact which the other does not . . . .”
Morey
v.
Commonwealth, supra
at 434.
Commonwealth
v.
Crocker, ante
353, 357 (1981).
Kuklis
v.
Commonwealth,
We turn, then, to an examination of the offenses for which the defendant was convicted, and conclude that each required evidence that the other did not. Unlawful possession of a machine gun, G. L. c. 269, § 10 (c), requires proof that a defendant possessed a weapon, and that the weapon was a machine gun as defined in G. L. c. 140, § 121. Further, the offense requires that the petitioner fail to obtain a license to carry the weapon under G. L. c. 140, § 131. Assault and battery by means of a dangerous weapon, G. L. c. 265, § 15A, requires neither that the weapon be a machine gun nor failure to obtain a license for the weapon. Assault and battery by means of a dangerous weapon requires an assault and a battery; unlawful possession of a machine gun does not. 5 Convictions under the two statutes thus fulfil the Morey requirement.
The petitioner claims, however, that we must look beyond Morey to discuss whether there is a legislative intent not to punish two factually related crimes, even if the elements of the offenses are distinct under Morey. See Commonwealth v. Jones, supra at 393-394. However, as we announced in Commonwealth v. Crocker, supra at 360, *502 “[i]n order to determine whether the Legislature in a given situation has authorized conviction and sentence under two statutory offenses, the Morey test provides a fitting rule of interpretation.” The elements of the offenses, rather than the facts adduced at trial, provide the measure of whether convictions are duplicitous. Unlawful possession of a machine gun and assault and battery by means of a deadly weapon are separate offenses. The prohibition against possession of a machine gun is designed to protect the public from the use of a particularly dangerous weapon by preventing its possession before it is used. The prohibition against assault and battery by means of a dangerous weapon is designed to forestall or punish a particular type of attack. While both statutes are designed to protect against violent crime, we recognize that they further distinct legislative policies. Those policies are best expressed in the Morey rule. We, therefore, conclude that the petitioner’s convictions for unlawful possession of a machine gun and assault and battery by means of a dangerous weapon contravene neither the double jeopardy clause nor any rule of the common law.
C.
Effective assistance of counsel.
The petitioner claims he was denied effective assistance of counsel at sentencing and on appeal. He bases his claim on the failure of his former counsel to raise or brief the cruel and unusual punishment and lesser included offense issues. Having found against the petitioner on the foregoing issues, we find no merit in his claim that his counsel exhibited “serious incompetency, inefficiency, or inattention . . . behavior . . . falling measurably below that which might be expected from an ordinary fallible lawyer.”
Commonwealth
v.
Saferian,
Judgments affirmed.
Notes
This court adjudges only whether the right of this petitioner to be free of cruel and unusual punishment has been violated in this case. See
United States
v.
Raines,
The petitioner bases his cruel and unusual punishment challenge on both the Eighth Amendment to the United States Constitution and on art. 26 of the Massachusetts Declaration of Rights. This court has never decided whether the language of the Eighth Amendment (“nor cruel and unusual punishments inflicted”) and art. 26 (“[n]o magistrate or court of law, shall . . . inflict cruel or unusual punishments”) have the same meaning.
District Attorney for Suffolk Dist.
v.
Watson,
It is unclear whether the petitioner is also claiming that the offense of possession is a lesser included offense of assault with intent to murder. Irrespective of whether the petitioner so argued, he must fail. Assault with intent to murder is even further attenuated from possession of a machine gun than is assault and battery by means of a dangerous weapon.
While this claim may be characterized as arising either under the double jeopardy clause of the Fifth Amendment to the United States Constitution or under the common law, we have ordinarily not rested decisions involving multiple convictions arising from the same event on constitutional grounds. In such cases, where at a single proceeding, a defendant has been convicted and sentenced for two offenses arising out of the same act, we have generally preferred to analyze the case under the common law Morey rule and have struck offending convictions as “duplicitous,” rather than as violative of double jeopardy. Commonwealth v. Crocker, ante 353, 358 n.8 (1981), and cases cited.
The petitioner argues that, since the Commonwealth proved that the dangerous weapon was in fact a machine gun, possession of a machine gun was an element of the proof of assault and battery by means of a dangerous weapon. The petitioner’s argument is misplaced. The Commonwealth need not have introduced the description of a machine gun contained in G. L. c. 140, § 121 (an element of proof needed to obtain a conviction for unlawful possession of a machine gun), to support the offense under G. L. c. 265, § 15A. The Supreme Court, construing the Federal analogue to the
Morey
test, stated that the test “focuses on the proof necessary to prove the statutory elements of each offense, rather than on the actual evidence to be presented at trial.”
