Hey Chadp82, I also reload and have been having major issues (see my 2 replies above). I have done the following to try and fix the problem, but have resigned myself to not using the specific bullet causing the jamming - Federal 150 gr Power-Shok softpoints.
I tried trimming cases to 2.000 (.010 less than max), seating bullet from 2.810 down to 2.630, tightening crimp, deburring cases before, etc. All measurements are in spec according to both Speer #9 and several online listings for 308, but this 1 bullet continues to jam when trying to chamber it.
I heard mention that Brownings are known to have tight chambers, but this is rediculous - I can only figure that because the ogive is farther forward (the bullet is short and fat) it is pressing into the lands earlier and that is causing the jamming. I don't want to have to seat the bullet down to short and have other issues...
Other issue I have is cleaning the recessed open area right before the chamber - how did you get in there? I found some small pieces of barss in there I think are from the jamming - they are scratching my cases. I cleaned as well as I could, but only way I could get in there was wrapping a cleaning swatch around a bronze brush and trying to swirl it around in there - not totally effective and I think I'm going to have to make a special tool just for this gun to clean that area out. I like how it shoots, but am getting frustrated with all the special issues I'm finding with it....
