Defendant first assigns as error the court’s instruction that counsel not propound a certain question to one of the State’s witnesses. The witness, who testified he had seen defendant enter the house trailer where the body of the victim was found, was asked, in conference and out of the presence of the jury, “Did you on the night of August 7th, 1973, call your wife, Earlene Furr and say, ‘Johnny [the defendant] has killed Doris, and I’m going to kill you’ ?” The witness answered in the negative and then the court instructed defendant’s counsel not to ask the question in the presence of the jury.
Defendant argues that the question would show bias on the part of the witness in that it would show he had an intimate friendship with the deceased. Such a conclusion on the part of the jury would be mere speculation. Evidence which has no logical tendency to prove a fact in issue in the case is inadmissible. See Godfrey v. Power Co., 190 N.C. 24, 128 S.E. 485 (1925), and 1 Stansbury, North Carolina Evidence, § 77, at 234 (Brandis rev. 1973). In addition, the witness answered in the negative, therefore, we can see no prejudice from excluding the question. The assignment is overruled.
On his second assignment of error, defendant contends the court erred in overruling defendant’s objections to questions put to the State’s witness, Frank G. Satterfield, Jr., a firearms expert with the S.B.I., for the reason that the State failed to lay a proper foundation. We find the assignment without merit.
As a witness for himself, defendant testified: “. . . I reached under my shirt and caught it [the gun] by the handle and pulled it out and was holding it in front of her, more or less in a parallel angle to her body .... As I was holding the gun, the [her] left arm came up and hit the gun and it went off. That’s all I know .... I was holding the gun out in front of her and it was about a foot to a foot and a half in front of her person. I did not point the gun at her nor did I have my finger on the trigger at any time. I just reached down and got it by the stock . . . .”
Agent Satterfield was called as a rebuttal witness by the State. After testifying with respect to his background, including 18l/2 years with the S.B.I., the last two years of which had *492been in the firearms section, Agent Satterfield, without objection, stated:
“I am able to identify State’s Exhibit No. 2 as a .22 caliber revolver by the name of Gecado. A revolver has a barrel of approximately 3% inches in length and the land and groove specifications are 8 grooves with a right twist. The pistol is a double action and single action weapon. When I say single action, I mean with the hammer cocked and double action, I mean when the hammer is not cocked. We checked to see how much weight was required to pull the trigger in both positions by firing the weapon. With the hammer cocked, it required approximately 4 to 4% pounds of pressure to pull the weapon. However, this would vary from cylinder to cylinder, but it was generally 4% to 4% pounds. This was for single action firing. By double action firing, the trigger pull was in excess of 5% pounds because the weights that we have are limited to a pull of 5*4 pounds.”
Thereafter, several questions were asked and objections thereto were sustained by the court, and a motion to strike an answer was allowed. Then, Agent Satterfield, over objection, testified that he studied the weapon for defects, that he did not find any defects “as to the mechanical operation of the weapon,” and that he had no difficulty in firing the weapon. Defendant contends that this testimony was erroneously admitted and cites State v. Phillips, 228 N.C. 595, 46 S.E. 2d 720 (1948), and State v. Foust, 258 N.C. 453, 128 S.E. 2d 889 (1963).
In State v. Phillips, supra, page 598, we find: “ ‘The general rule as to the admissibility of the result of experiments is, if the evidence would tend to enlighten the jury and to enable them to more intelligently consider the issues presented and arrive at the truth, it is admissible. The experiment should be under circumstances similar to those prevailing at the time of the occurence involved in the controversy. They need not be identical, but a reasonable or substantial similarity is sufficient’—Edwards, J., in Shepherd v. State, 51 Okla. Crim., 209 300 P., 421.”
While recognizing the rule restated in Phillips, we do not think the rule rendered inadmissible the evidence challenged here. It would appear that Agent Satterfield’s testimony related more to testing the death weapon for defectiveness than it did to performing an experiment as was true in Phillips. We note *493again that a large part of the agent’s testimony was not objected to, only his conclusion as to defects. We also think that the challenged testimony is distinguishable from that declared inadmissible' in Fomt. In the first place, in Foust the testimony relating to testing or experimenting with the weapon was objected to. Secondly, the testimony in that case more clearly tended to show an “experiment” than the testimony challenged here. Agent Satterfield in no way attempted to simulate the version of the occurrence as described by defendant, and then show that it could not have happened that way.
Defendant’s third and fourth assignments of error relate to the court’s charge to the jury. Considering the instructions as a whole, and contextually, we conclude that they were free from prejudicial error.
We hold that defendant received a fair trial, free from prejudicial error.
No error.
Judges Hedrick and Carson concur.
