Hello all, first off this is my first post . Just want to say thank you to all the knowledgeable people who contribute to this forum. Other then reloading manuals, this forum is where I have learned most of what I know to the point I am at on the subject of reloading,thanks. My issue is this. I have a new 6BR, 8 twist Krieger,bat sv action,272 no turn neck. I have been working up a load with 95 Berger hunting vlds with varget, 15 thou of the lands and started at 29.5 grains and went up in two grain increments . No pressure signs at all until 30.2. At 30.2 the cci 450 primer had a black ring of residue around it . The primer never blew out of the case. Should note this is only 2nd firing on new gold box brass. It also left a very small divit in the bolt face . Of course I stopped continuing firing higher charges. There was no hard bolt lift or flattening of the primer, or ejector marks. From what ive read this seems like a light load for this bullet. The loaded round measures 1.629 to the ogive touching the lands.Could I be seeing high pressure at so low of a load? Sorry for the long post but help would be appreciated, thanks!.
