NOTICE:  Eighth Circuit Rule 28A(k) governs citation of unpublished opinions and provides that they are not precedent and generally should not be cited unless relevant to establishing the doctrines of res judicata, collateral estoppel, the law of the case, or if the opinion has persuasive value on a material issue and no published opinion would serve as well.UNITED STATES of America, Appellee,v.Merle A. DACK, also known as Pete Dack, Appellant.
No. 95-3693.
United States Court of Appeals, Eighth Circuit.
Submitted June 18, 1996.Decided June 24, 1996.

Before McMILLIAN, WOLLMAN, and MURPHY, Circuit Judges.
PER CURIAM.


1
Merle A. Dack challenges the 63-month sentence imposed by the district court1 after he was convicted of conspiring to distribute and possess with intent to distribute a mixture or substance containing a detectable amount of methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1) and 846.   We affirm.


2
Dack first contests the quantity and type of methamphetamine attributed to him.   The Guidelines prescribe a base offense level of 26 for offenses involving between 100 and 400 grams of "Methamphetamine" or between ten and forty grams of "Methamphetamine (actual)."   U.S.S.G. § 2D1.1(c)(7).  "Methamphetamine (actual)" means "the weight of the controlled substance, itself, contained in the mixture or substance."   U.S.S.G. § 2D1.1(c), note *.   Dack admitted his involvement with at least 155 grams of methamphetamine, but maintains the district court should not have held him accountable for the entire weight of unseized and untested methamphetamine because there was evidence of the drug's purity from which the court could have determined the amount of methamphetamine (actual) at issue.   We disagree.   In cases involving a mixture or substance containing methamphetamine--as is undisputedly the situation here--the court is to "use the offense level determined by the entire weight of the mixture or substance, or the offense level determined by the weight of the ... methamphetamine (actual), whichever is greater."   Id. (emphasis added);  United States v. Newton, 31 F.3d 611, 614 (8th Cir.1994).


3
We conclude the district court did not clearly err in holding Dack accountable for 100 to 400 grams of methamphetamine.  See Newton, 31 F.3d at 614 (standard of review);  United States v. Wright, 29 F.3d 372, 374 (8th Cir.1994) (district court properly relied on defendant's admission in determining drug quantity).   Dack's argument that the court used unreliable evidence in making this finding is meritless.   Nor did the district court clearly err in finding that the case involved d-methamphetamine, see United States v. Jennings, 12 F.3d 836, 838 (8th Cir.1994) (standard of review), because Dack conceded as much at the evidentiary hearing, the government's undisputed evidence established that the substance was d-methamphetamine, and "random testing of substances for drug content is sufficient for sentencing purposes," United States v. Roach, 28 F.3d 729, 735 (8th Cir.1994);  see United States v. Griggs, 71 F.3d 276, 282 n. 2 (8th Cir.1995) (court need only find some of mixture was d-methamphetamine to sentence defendant for d-methamphetamine or methamphetamine using entire weight of mixture).


4
Dack also contends he was entitled to an acceptance-of-responsibility reduction.   While conviction by trial "does not automatically preclude a defendant from consideration for such a reduction," U.S.S.G. § 3E1.1, comment.  (n.2), we conclude the district court did not clearly err in denying Dack the reduction, because Dack proceeded to trial, requiring the government to prove the elements of its case, not to assert and preserve issues unrelated to factual guilt;  and during allocution, he continued to challenge the veracity of the witnesses who testified against him.   See id.  (reduction not intended for defendant who goes to trial, is convicted, and only then admits guilt and expresses remorse);  United States v. Amos, 952 F.2d 992, 995 (8th Cir.1991), cert. denied, 503 U.S. 1010 (1992).


5
Accordingly, the judgment of the district court is affirmed.
