OPINION OF THE COURT
Frank Earl Senk appeals the denial of his petition for writ of habeas corpus. The petition alleges that Senk was denied his sixth amendment right to effective assistance of counsel by virtue of his lawyer’s failure to pursue, in post-trial motions and on appeal, a challenge to the trial court’s charge on first degree murder, which Senk alleges contained an impermissible mandatory presumption on the element of intent. The district court held that because the judicial decisions that arguably render unconstitutional the jury instruction on intent were not decided until many years after Senk’s trial, his counsel’s failure to pursue the claim did not rise to the level of ineffective assistance. We will affirm.
I.
On April 5, 1962, Senk was convicted of first degree murder in the Court of Common Pleas of Columbia County, Pennsylvania. In the jury charge, the trial court gave the following instruction:
[I]n all cases of malicious killing, if no intention to kill can be inferred or collected from the circumstances, then the verdict would be guilty of murder of the second degree.
Our courts have held that the intentional, unlawful and fatal use of a deadly weapon upon a vital part of the body gives rise to a presumption of fact that ma[l]ice and intention to kill exists. This would likewise apply to repeated blows, or a severe blow upon a vita[l] part of the body. This is a presumption of fact based upon common knowledge that such conduct is reasonably likely to cause death. Every person is presumed to intend the natural and probable consequences of his act or acts. Therefore, if one does an act, the consequences of which are almost certain to cause death, there would be a presumption that that was what he intended to do. Being a presumption of fact, it may be rebutted only by other circumstances in the case. This is solely a jury question.
At the conclusion of the court’s charge, trial counsel made the following objection:
And now, April 5th, counsel for the defendant respectfully excepts to the Charge in general, and specifically, to that part of the Charge wherein the Court stated in substance that the jury could presume from the use of a deadly weapon that the defendant must have known that his act was likely to cause death, and knowing this, he must be presumed to intend the death which was the probable and ordinary consequence of such an act.
Trial counsel did not, however, pursue this claim in post-verdict motions or on direct *613 appeal. 1 This claim was also ignored in the course of two post-conviction petitions and two federal petitions for writ of habeas corpus. 2 Trial counsel filed Senk’s first post-conviction petition. In the subsequent collateral proceedings, Senk pursued his claims either pro se or with the assistance of three different attorneys.
For the first time, in April, 1983, in his third petition under the Pennsylvania Post Conviction Hearing Act, 42 Pa.Cons.Stat. Ann. § 9541
et seq.
(1982), Senk alleged that he received ineffective assistance of counsel at trial and on appeal because counsel failed to challenge the jury instruction on intent. The Court of Common Pleas’ denial of his petition was affirmed without opinion by the Pennsylvania Superior Court.
Commonwealth v. Senk,
II.
Senk claims that his trial counsel and all subsequent counsel were ineffective for failing to pursue a merited claim, i.e., the unconstitutionality of the jury instruction on intent. Citing
Sandstrom v. Montana,
In
Sandstrom,
the defendant argued at his state trial that his personality disorder, aggravated by alcohol consumption, prevented him from forming the requisite intent for “deliberate homicide.” The trial court instructed the jury that “[t]he law presumes that a person intends the ordinary consequences of his voluntary acts.” The Supreme Court, granting certiorari “to decide the important question of the in
*614
struction’s constitutionality,”
In Senk’s case, the jury was informed that the presumption on intent “may be rebutted ... by other circumstances in the case,” and that the question of intent is “solely a jury question.” The instruction, therefore, did not create a “conclusive mandatory presumption.” Senk also argues, however, that the instruction created a “mandatory rebuttable presumption.” In contrast, the Commonwealth maintains that the instruction created a “permissive inference” that did not impermissibly shift the burden of proof to the defendant.
Senk claims that his sixth amendment rights to effective assistance of counsel at trial,
Strickland v. Washington,
In
Strickland,
the Supreme Court held that “[t]he benchmark for judging any claim of ineffectiveness must be whether counsel’s conduct so undermined the proper functioning of the adversarial process that the trial cannot be relied on as having produced a just result.”
It is all too tempting for a defendant to second-guess counsel’s assistance after conviction or adverse sentence, and it is all too easy for a court, examining counsel’s defense after it has proved unsuccessful, to conclude that a particular act or omission was unreasonable. A fair assessment of attorney performance requires that every effort be made to eliminate the distorting effects of hindsight, to reconstruct the circumstances of counsel’s challenged conduct, and to evaluate the conduct from counsel’s perspective at the time. Because of the difficulties inherent in making the evaluation, a court must indulge a strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance; that is, the defendant must overcome the presumption that, under the circumstances, the challenged action “might be considered sound trial strategy-”

The most formidable obstacle that Senk faces in prevailing on his ineffective assistance claim is the fact that the
Sandstrom
decision was decided seventeen years after his trial in Columbia County. Consequently, Senk contends that the
Sandstrom
and
Francis
decisions “merely represent an application of the principle set forth” in
Morissette v. United States,
In response, the Commonwealth disputes Senk’s characterization of
Morissette
as the seminal case setting forth the rules on the validity of this kind of jury instruction. Further, the Commonwealth observes that during Senk’s trial and direct appeal, the United States Supreme Court had only begun to make the guaranties of the Bill of Rights obligatory upon the states through the due process clause of the Fourteenth Amendment, and therefore those accused of crimes in state courts had not “grown accustomed” to looking to the Federal Constitution as a guarantor of their rights. Therefore, the Commonwealth emphasizes that as a matter of state law, the validity of the intent instruction given at Senk’s trial, i.e., that a person intends the natural consequences of his acts and that an intent to kill may be presumed from the application of a deadly weapon to a vital body part, was “a matter of long-standing precedent,” traceable to
Commonwealth v. Drum,
This court has observed that we will not often decide that attorneys have acted unreasonably under prevailing professional standards when they do not make an objection which could not be sustained on the basis of the existing law, as there is no general duty on the part of defense counsel to anticipate changes in the law.
Government of Virgin Islands v. Forte,
In MoHssette, the defendant was charged under 18 U.S.C. § 641, which provides that “whoever embezzles, steals, purloins, or knowingly converts” government property is punishable by fine and imprisonment. The defendant admitted that he took government property, but insisted that he believed that the property had been abandoned, and therefore that he did not intend to steal it. Deciding that intent to steal was not an element of the crime charged, the trial court refused to instruct the jury on this defense. Instead, the court instructed:
[I]t is no defense to claim that [the property] was abandoned, because it was on private property.... [I]f this young man took this property (and he says he did), that was on the property of the United States Government (he says it was) ... [then] he is guilty of the offense charged.... The question on intent is whether or not he intended to take the property. He says he did. Therefore, if you believe either side, he is guilty.
Morissette,
[that a] presumption which would permit but not require the jury to assume intent from an isolated fact would prejudge a conclusion which the jury should reach of its own volition. A presumption which would permit the jury to make an assumption which all of the evidence taken together does not logically establish would give to a fact an artificial and fictional effect. In either case, this presumption would conflict with the overriding presumption of innocence with which the law endows the accused and which extends to every element of the crime.
Id.
at 275,
Despite this broad language, which the
Sandstrom
Court quoted extensively in support of its holding that a mandatory conclusive presumption on intent violates the Due Process Clause,
see Sandstrom,
In
Leland,
the Court considered whether an Oregon statute violated the Due Process Clause of the Fourteenth Amendment by requiring that criminal defendants pleading insanity establish their innocence by disproving beyond a reasonable doubt that they were capable of forming the requisite mental element of the crime charged. The Court had previously held in
Davis v. United States,
In fact, it was not until 1970 — eighteen years after the Morissette decision and eight years after Senk’s trial — that the Supreme Court emphatically specified
[ljest there remain any doubt ..., we explicitly hold that the Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged.
In re Winship,
Furthermore, the jury instruction on intent announced to the Senk jury differed significantly from the instruction given in
Morissette.
As we noted earlier, the intent instruction that the
Morissette
jury received, as distinguished from the intent instruction in Senk’s trial, established a conclusive presumption and thus completely removed the issue of intent from the jury’s consideration. It is for this reason that the
Sandstrom
Court characterized the
Morissette
instruction on intent as a “conclusive presumption,”
The several
pre-Sandstrom
decisions cited by Senk, which invalidate criminal convictions where the jury received instructions on intent similar to the instruction given in
Morissette,
do not dictate a different result. In each of these cases, the defendant was tried in federal, rather than state court, and the jury instruction created a conclusive presumption on the issue of intent, rather than a burden-shifting presumption.
See Chappell v. United States,
In hindsight, the evolution from the broad principles in
Morissette
to the concrete rules of
Sandstrom
appears to be a textbook example of the harmonious development of the common law. The
Strickland
directive, however, mandates that we avoid these “distorting effects,” by “recon-structLing] the circumstances of counsel’s challenged conduct, and ... evaluate the conduct from counsel’s perspective at the time.”
Accordingly, we will affirm the judgment of the district court.
Costs to be taxed against appellant.
Notes
. Generally, only claims argued in post-verdict motions are preserved for appeal under Pennsylvania law. See Pa.R.Crim.P. 1123(a)(Purdon Supp.1988).
. The history of appellate litigation of Senk’s claims can be summarized as follows. On direct appeal, the Pennsylvania Supreme Court affirmed Senk’s first degree murder conviction and sentence of death.
.This court appointed a federal public defender from the Middle District of Pennsylvania to represent Senk in this appeal.
. Senk also claims that each of his subsequent attorneys were ineffective for their failure to raise this sixth amendment claim in his state and federal post-conviction petitions. Our conclusion that neither trial counsel nor first appellate counsel was ineffective obviates the need to evaluate the performance of subsequent counsel.
See Tillett v. Freeman,
. Senk has argued neither to this court nor to the Pennsylvania courts that
Sandstrom,
as a newly-announced constitutional rule, should be applied retroactively to remedy a due process violation at trial. Therefore, we do not have occasion to address this issue.
See Dooley v. Petsock,
. In
Forte,
we found the "unique" circumstances where,
'pre-Batson,
an attorney who failed to
*616
preserve a
Batson
objection provided ineffective assistance of counsel. We rested our decision on that fact that the Supreme Court had long held that a state denies equal protection of the laws when a black is put on trial before a jury from which blacks are purposefully excluded, and that numerous Batson-like objections were being made at the time in other cases, including in the Virgin Islands.
