shotgun sam Posted September 12, 2011 Report Share Posted September 12, 2011 What is the maximum safe powder compression you would use in 223 and 308 Link to comment Share on other sites More sharing options...
6.5shooter Posted September 12, 2011 Report Share Posted September 12, 2011 I use 27 gr varget in a 223 lapua case behind a 60 vmax and it is slightly compressed. When pressing down the press handle when seating the bullet there is a slight crush being heard and felt. I use a long drop tube when filling the case with powder and this helps slightly and gives a consistent crush whereas I found without the drop tube it was very inconsistent. I think as long as you dont have any over pressure signs in youre case the limiting factor will be bullet movement. What I mean is, when you seat youre bullet, check it to make sure the bullet hasnt moved to lengthen OAL. I think if I used a slightly faster powder than varget with the 60 grainers I would be better off but the accuracy is superb so I dont want to change a proven combination. Hope this helps.
