[QUOTE="Bart B, post: 364990, member: 5302"] Sierra's 190 HPMK was a favorite for 1000 yard matches in the .308 Win. It won a lot of matches at 600 through 1000 yards and set some records along the way. These bullets would leave about 2550 to 2600 fps from 26 inch barrels. But after Sierra came out with their 155-gr. Palma bullet, shot it in 30 inch barrels faster than 3000 fps, it out performed Sierra's 190. Bucked the wind for all practical purposes just as good as the 190. And Sierra's new 155-gr. Palma bullet's got a higher BC than their original one. I wouldn't get impressed by the "VLD" claim for some bullets. A test was made some years ago shooting Sierra 190 HPMK's and Berger 185 VLD's out of the same barrel through chronographs at the firing line and 1000 yards down range. When both bullets left at the same muzzel velocity, the Sierra's went through the 1000-yard chrono over 50 fps faster than the Bergers. So the Berger's were really "ND" or normal drag bullets; probably about the same as Sierra 180 HPMK's. [/QUOTE]
