On July 31, 1971, Nаncy Lannon the estranged wife of the petitioner, Reginald Lannon, was fatally wounded by a shot from a shotgun held by the petitioner. He was indicted for murder in the first degree and tried to a jury. At trial, the petitioner testified that the fatal shot was accidentally caused when a screen door hit the gun he was holding, causing it to discharge. The defense also offered expert psychiatric testimony to the effect that the petitioner was a paranoid schizophrenic, had a suicidal preoccupаtion, and suffered from diminished mental responsibility. The jury found Lannon guilty of murder in the first degree on February 18, 1972, and recommended that the death penalty not be imposed. The judge sentenced the petitioner to life imprisonment at the Massachusetts Correctional Institution at Walpole. The judgment of conviction was affirmed by this court in 1974.
Commonwealth
v.
Lannon,
The petitioner filed this petition for writ of error with the county court on July 28, 1978. A single justice denied the writ, and the petitioner now appeals from that order. The petition alleges that the trial judge’s charge to the jury improperly shifted the burden of proof on the issue of accidental death.

The petitioner relies on the constitutional principles enunciated by the United States Supreme Court in
Mullaney
v.
Wilbur,
The Commonwealth argues that, although a defendant may raise a new constitutional issue by writ of error, we should require consideration of these issues first on a motion for a new trial. We disagree. This is not a case where, underlying the alleged constitutional errors, there are factual disputes which are appropriately resolved by a trial judge on a motion for a new trial.
Gibney
v.
Commonwealth,
The Commonwealth further contends that since the petition filed pursuant to G. L. c. 250, § 11, was denied by a single justice of this court, the only issue before this court is whether the single justice abused his discretion.
Aronson
v.
Commonwealth,
Likewise, this petition is distinguishable from the petition considered in
Aronson, supra,
which sought to raise “errors in the determination of facts at a trial.”

The petitioner here argues an error of law of constitutional dimension. Cf.
Guerin
v.
Commonwealth,
In the portion of the judge’s charge to the jury dealing with the elements of murder, the judge stated: “Where a killing is caused by the intentional use of fatal force without circumstances serving to mitigate, to justify the act, you may infer that malice is present.” The petitioner contends that this language impermissibly suggested to the jury that he had the burden of “justifying” his actions in order to avoid being convicted of murder.
Mullaney
v.
Wilbur,
The petitioner further contends that certain language in the charge such as the following, served to reinforce the idea that he bore the burden of proof: “[Y]ou will consider whether or not there was, in fact, here a killing, intentional, *790 but committed on sudden impulse and a sudden transport of passion and adequate provocation. If that is your judgment on the matter, then he could be found guilty of manslaughter.
“Now, getting into the involuntary manslaughter situation, you have the testimony of this defendant that the gun went off accidentally, and that he had no intention of shooting that gun and no intention to kill.
“If yоu accept that story, then you must consider whether or not, if you find it to be a fact, that loading that shotgun, as he said he did, and apparently with the safety off, and going to the door, was such wanton, reckless misconduct that he should be responsible for the naturаl and probable consequences of that reckless handling of the gun.”
The petitioner argues that use of language such as “if you accept that story,” “you must consider,” and “if you find” impermissibly suggested to the jury that the petitioner had the burden of persuading them оf the presence of circumstances which would warrant conviction of a lesser crime than murder.
Connolly
v.
Commonwealth,
Malice is an essential element of murder. Malice is not present where a defendant acted under adequate provocation or whеre a gun discharged accidentally. The Commonwealth has the burden of proving beyond a reasonable doubt, in any case where the issues are fairly raised, that there was not reasonable provocation and that the shooting was not accidental.

The judge should so charge the jury.
Mullaney
v.
Wilbur,
The defendant contends that reversal is required in this case because the judge failed to charge the jury in explicit terms that the absence of mitigating circumstances had to be proved by the Commonwealth beyond a reasonable doubt. However, in Stokes, we stated that “[i]n adopting the ruling of Mullaney . . . we are not required to apply a narrow and precise test to the instructions given by the judge. If Mullaney imposed such a requirement, reversal would follow with mathematical certainty in all cases where self-defense or reasonable provocatiоn had been raised in the evidence sufficiently and where the burden of proof as to these precise issues had not been placed by specific language on the Commonwealth” (footnote omitted). Id. at 590. We also stated, “ [I]n any case wherе the requirements of Mullaney are placed in issue, the charge to the jury must be examined in its entirety to determine whether the constitutional requirements have been met.” Id. at 590-591.
Viewing this charge in its entirety, we do not find it to be constitutionally inadequate. The judge instructed the jury that thе defendant is presumed to be innocent and that the Commonwealth has the burden of proving guilt beyond a reasonable doubt. The instructions on this point were explicit and lengthy. During this portion of the charge, the judge stated: “The presumption of innocencе also means this. That under our law there is no obligation upon a defendant to prove his innocence. ... If he is to be found guilty, he must be found guilty not because he has proved his innocence, or failed to prove his innocence, I might say, but because thе Commonwealth has sustained its burden of proving the guilt of a defendant beyond a reasonable doubt.”
We agree with the petitioner that the aspect of the instant charge which is most troubling is the repeated use of language such as “if you acceрt that story,” “you must consider,” and “if you find.” As we stated in Connolly, supra, in relation to the issue of self-defense: “The . . . instruction *792 that homicide may be justifiable if committed in self-defense . . . did not fully comport with the . . . Stokes requirement that self-defense be ‘established ... as negating a finding of malice.’ Yet the defect might be thought not enough in itself, in a pre-Mullaney trial, to hold an instruction bad. The greater difficulty with the charge lies in its repeated use of ‘finding’ language when explaining the law of self-defense” (footnote omitted). Connolly, supra at 533.
Much of the language about which the defendant complains is contained in the portion of the charge dealing with diminished responsibility. This objectionable language need not concern us, for as we stated in the defendant’s direct appeal, “we [have] rejected the notion of a middle ground betweеn insanity and normal criminal responsibility which would not exonerate a defendant but would reduce the degree of his crime .... [0]n this issue the charge to the jury was more favorable to the defendant than was warranted by applicable precedent.”
Commonwealth
v.
Lan-non,
We add that the “finding” language in the case at bar should not constitute a basis for reversal because the defense “invited” this error in its rеquest for instructions to the jury. Many of the requested instructions utilize the same language now complained of. For example, the petitioner requested that the judge give the following instruction: “ If the jury finds that the defendant killed Nancy Lannon after provocation or in the heat of emotion it must find him guilty qf no crime more serious than manslaughter.” The petitioner cannot now object to the judge’s use of wording
*793
which his own counsel proposed for inclusion in the instructions.
United States
v.
McCracken,
The petitioner further argues that the judge erred in instructing the jury that it would be permissible for them to infer “that a person ordinarily intends the natural and probable consequences of any act which is knowingly done. And if a person uses upon another an instrument or weapon of such a nature and in such a way and under such circumstances that the use would naturally and probably result in the death of the other, you may infer or conclude that he did so with that specific intention to kill. You are not required to come to that conclusion, but you may do so. . . . And just as a specific intent to kill may be inferred from the circumstances, so malice may be inferred from the circumstances.” The petitioner contends that this language represents another facet of the burden-shifting theme which we have addressed above. While this challenge was not clearly raised in the petition, 5 we address it as it relates to the issue of shifting the burden of proof with respect to accidental death.
The particular inferences described by the trial judge in the case at bar have been held valid by this court. Sеe
Commonwealth
v.
McInerney,
Judgment affirmed.
Notes
The petitioner further argues that the judge’s failure to charge the jury on the issue of criminal responsibility denied him a fair trial. This alleged error was not raised in his petition for writ of error, nor was it set forth in his claim of exception. The petitioner is bound by his pleadings in his assignment of errors. See
Jones
v.
Commonwealth,
Since the petition was filed prior to the effective date of the new Massachusetts Rules of Criminal Procedure, we discuss it in the context of the rules in effect priоr to July 1,1979. See Mass. R. A. P. 1B,
The writ is available to review certain errors of fact, but as to these errors, the scope of review is narrow. The writ cannot be used to re-try matters of fact which might have been put in issue and tried in the original case.
MacEachern
v.
S.S. White Dental Mfg. Co.,
In sustaining its burden of proof that the shooting was not accidental, the Commonwealth is aided by a permissible inference of malice from the intentional use of a deadly weapon. See text infra at 793.
See note 1, supra.
