   PER CURIAM:

Petitioner Jerry Mack Dorrough, a Fifth Circuit veteran, seeks once more to escape the finality of his much parsed conviction for robbing and placing in jeopardy the life of a federal postal employee in violation of 18 U.S.C.A. § 2114. We have again scrutinized Dorrough’s plea of guilty, and we find all his claims of imperfection without merit in light of our prior decisions. See Dorrough v. United States, 5 Cir. 1967, 385 F.2d 887, aff’d en banc, 1968, 397 F.2d 811.

The judgment of the district court is affirmed. 
      
      . This case represents the fourth time Dorrough has challenged his guilty plea under 28 U.S.C.A. § 2255. See Dorrough v. United States, 5 Cir. 1964, 327 F.2d 667; Dorrough v. United States, 5 Cir. 1965, 344 F.2d 125; Dorrough v. United States, 5 Cir. 1967, 385 F.2d 887, aff’d en banc, 1968, 397 F.2d 811, cert. denied, 1969, 394 U.S. 1019, 89 S.Ct. 1637, 23 L.Ed.2d 44. See also Dorrough v. State of Texas, 5 Cir. 1971, 440 F.2d 1063.
