Edwаrd Byron Ballard appeals the district court’s dismissal of his habeas corpus petition on the merits. He is incarcerated in California for armed robbery and argues that the definition of “use of a firearm” used to enhance his sentence was broader *455 than the California sentencing laws require, thereby denying him due process. He also argues that even if the state court’s definition of firearm use was the correct one, there was sufficient evidence of use, according to the definition, in only two of the 18 robbery counts. This court has jurisdiction under 28 U.S.C. § 2253. We affirm.
BACKGROUND
Mr. Ballard was convicted of 18 counts of robbery, 3 counts of attempted robbery, and 1 count of assault with a deadly weapоn. All counts stemmed from two bar robberies conducted with several accomplices on two different days. The jury found that Mr. Ballard had used a firearm in each count. Consequently, the judge enhanced his sentence once for each bar robbery under Cal.Penal Code § 12022.5, 1 and classified each count as a violent felony for sentenсing purposes under Cal. Penal Code § 667.5(c)(8). The judge imposed consecutive prison sentences for each count under § 1170.1(a) for a total sentence of 26 years, 8 months. 2
The judgment was affirmed on appeal and habeas corpus petitions raising the instant arguments to the California Court of appeal and Supreme Court werе denied. Mr. Ballard then filed a habeas petition with the U.S. District Court, Central District of California which was dismissed on the merits. Mr. Ballard appeals that dismissal to this court.
DISCUSSION
Denial of a petition for writ of habe-as corpus is reviewed de novo.
Norris v. Risley,
1. Habeas Corpus Procedure
Contrary to appellant’s suggestion, the magistrate and district court judge complied with the governing rules in the prоcedures they employed in this case. First, although an evidentiary hearing in a habeas corpus proceeding to determine facts is mandatory when certain procedural deficiencies occurred in the state court’s fact-finding procedures,
Townsend v. Sain,
Second, the relevant portions of the state court trial transcripts were lodged with the district court,
see Ballard v. Estelle,
No. CV 89-6264-RB, Notice of Lodging Documents (C.D.Cal. Feb. 5, 1990). As seen in his reports, the magistrate conducted the necessary review of the transcripts as required.
See Lincoln v. Sunn,
Finally, it was not improper for the magistrate to review the appellant’s objections prior to the judge’s review in order to correct any errors he might have made. If the magistrate had made any new findings or recommendations in his final report, the appellant’s argument that he should have been given anothеr opportunity to object might have some merit. As that was not the case here, no impropriety existed.
II. Applications of State Law are Cognizable in Habeas Proceedings
State laws may give rise to liberty interests protected by the Fourteenth Amendment.
Board of Pardons v. Allen,
III. Definition of “Use”
The appellant misstates California’s requirements for finding “personal use” of a firearm for sentence enhancement purposes under Cal.Penal Code § 12022.5. 5 The California Supreme Court discussed the difference between being аrmed and use of a firearm in People v. Chambers:
By employing the term “uses” instead of “while armed” the Legislature requires something more than merely being armed.... Although the use of a firearm connotes something more than a bare potential for use, there need not be conduct which actually produces harm but only conduct which produces a fear of hаrm or force by means or display of a firearm in aiding the commission of one of the specified felonies. “Use” means, *457 among other things, “to carry out a purpose or action by means of” to “make instrumental to an end or process” and to “apply to advantage.” (Webster’s New Internat. Diet. (3d ed. 1961).) The obvious legislative intent to deter the use of firearms in the commission of the specified felonies requires that “uses” be broadly construed.
The undisputed facts of this case show that Mr. Ballard used his gun in a menacing manner to accomplish his purposes against at least some of the victims during the bar robberies. In Poor Richard’s Bar in the course of enforcing his requеst that the patrons congregate in the women’s bathroom, Mr. Ballard reacted to sudden moves by one patron, Mr. Volger, by raising his gun. In the Beaver Pond Bar, Mr. Ballard waved his gun at one of the patrons, Mr. Fox, who was attempting to leave, to prevent him from doing so. Obviously, Mr. Ballard intended his actions to have a forceful effect in accomplishing his felonious purposes. The evidence clearly fits within the definition of personal use used in the California Supreme Court cases discussed above.
The appellant attaches undue importance to the categorizations of California appeals courts applying the personal use standard. In
Hays,
the Fourth District Court of Appeals reviewed the 18 previous California cases addressing use enhancement and concluded that in all of these cases the defendant either aimed, cocked, fired, or displayed the gun in a menacing manner accompanied by words threatening a more violent use.
Two appeals court cases following
Hays
echoed the categories that emerge from the case histories but, again, not in order to fix those categories in stone.
People v. Jacobs,
IV. Gun Use in Each Count
Finally, the appellant argues that even if the personal use finding can be sustained in one or two counts, there was insufficient evidence of personal use in every other count. Mr. Ballard’s argument is inconsistent with California law. In a simultaneous robbery of multiple victims
*458
by multiple perpetrators, use of a firearm against at least one victim satisfies the personal use requirement such that a gun use finding attaches to every crime for which the defendant is responsible during the transaction, including crimes for which the defendant is only vicariously liable.
People v. Walker,
Even assuming for ■ sake of argument that defendant’s compаnion fired the shots, we do not find defendant’s own gun use so separate from the actual shootings that prejudice could be inferred from the court’s failure to more fully instruct [regarding gun use].
Id.,
There being no question that appellant personally used a firearm during the course of the instant robbery, the enhancement was entirely proper [for the murder count] regardlеss of whether or not he also personally shot the victim.
Id. 6
In an earlier case, also named
People v. Walker,
Our case does not involve a murder or attempted murder committed by a code-fendant during the course of the robbery in which Mr. Ballard personally used a gun. It does involve multiple robbery counts naming multiple victims in two hold-ups. Mr. Ballard used a gun during the robberies to guard the door, move groups of victims from one plaсe to another, and threaten victims who showed signs of not cooperating. It would be inconsistent with Walker and with the nature of robberies involving multiple perpetrators and victims, to say a gun use finding as to Mr. Ballard applies only against those victims who challenged him and thereby elicited his menacing behavior. He personally used his gun in the course of simultаneously robbing multiple victims, and a threat to one victim was a threat to all. His personal gun use during the course of the robberies was inextricably related to the robbery of each victim and cannot be separated from any of the robbery counts, including those in which his codefendants were the principal actors.
CONCLUSION
We AFFIRM the dismissal of Mr. Ballard’s habeas corpus petition. There was no federally cognizable abuse of California law in this case.
. It is not clear whether Mr. Hankey was indicted for robbery, or for any crime other than felony murder, arising from the incident. The fact that he was convicted of only the felony murder count may have influenced the court to allow a gun use finding to attach to that count, when in a different case involving multiple counts the court would only allow the finding to attach to counts for which the defendant had personally used a gun. Other California appeals courts faced with multiple count convictions have said that gun use findings are not appropriate for the counts in which the defendant is liable only vicariously.
People v. Nguyen,
Notes
. California Penal Code § 12022.5 allows for additional, consecutive punishment of two years for those who personally use a firearm in the commission of a felony (the gun use enhancement). However, the California Supreme Court has established that although gun use under § 12022.5 may be found for each count when multiple criminal counts arise from a single criminal incident, a gun use enhancement can be imposed only once per incident.
In re Culbreth,
. In his brief at 1-2, appellant argues that the fact that the gun use findings classified each сount as a violent felony "permitted” the judge to impose consecutive sentences. The decision to impose consecutive or concurrent sentences for multiple count convictions is not controlled by the classification of the felonies as violent or not. When the judge .chooses consecutive sentenсing, § 1170.1(a) sets the rules for consecutive sentencing for both violent and non-violent felonies. The appellant also misquotes § 1170.1(a) in n. 3 of his brief. Contrary to his quotation, one-third of the middle term of imprisonment provided by statute is imposed for both violent and non-violent felonies under § 1170.1(a). The sentencing difference between violent and non-violent fеlonies is that sentencing for non-violent felonies includes a five-year cap for subordinate terms and excludes any enhancements. Sentencing for violent felonies has no cap and includes one-third of any enhancements.
. A mixed question of law and fact, which might also be resolved more properly in an evidentia-ry hearing, involves the application of an undisputed rule of law to the undisputed facts.
Norris,
. Appellant does not object to the state court record itself. Consequently, the district court judge was not required to repeat the magistrate’s review of the record. The portions of the record quoted in the magistrate’s reports and in the appellant’s objections sufficed to allow the judge to make a de novo determination of the findings and recommendations objected to. See 28 U.S.C. § 636(b)(1); Rule 8(b) of the Rules Govеrning Section 2254 Cases in the United States District Courts.
.Section 12022.5(a) provides in relevant part: "[A]ny person who personally uses a firearm in the commission or attempted commission of a felony shall, upon conviction of such felony or attempted felony, ... be punished by an additional term of imprisonment in the state prison for three, four, or five years.... ”
