[QUOTE="James Jones, post: 162157, member: 8843"] Alot has to do with the barrel , you will likely not be able to get the velocity out of you Kreiger and keep the bullet together as you would with a Shilen. The Shilen has 8 lands and grooves and is a buttonrifle barrel which mean the lands are a little shallow compaired to a cut rifled barrel like the Kreiger and the Kreiger only has 4 lands a grooves. Generaly speeking the fewer the lands and grooves the bigger they are and harder they will be on thin jacketed bullet , this is why alot of guys cant get the velocity they expect out of a 3 groove Lilja or Pac-Nor. I have seen a 6mm-06Ai run a 105 A-max out to over 3800 fps in a 30" Hart barrel with awsome accuracy to 1000yds. If I were gonna try to get top velocity out of a barrel I would go with either a Rockcreek , Obermeyer or Broughton with their 5R land and groove desgine , these barrels generaly get higher speeds with any bullet weight and the 5R land desgine isin't quiet as rough on the bullet jacket [/QUOTE]
