If and I do mean "if", you are not experiencing pressure signs, use a drop tube and vibrate or tap the case to settle the powder. One of my previous loads with my AI, using a powder a bit too slow filled the case just short of the rim.....not the neck! I then seated, very slowly and carefully a 270 grain Barnes ( long, copper bullet). If seated fast.....it would bulge the case! I'll readily confess that this is a bit extreme. Getting an additional 2 to 4 grains of powder into the case, should be very doable!
Pretty much, every rifle load I have is somewhat compressed. Again, if all indicators show you are within safe pressures.....continue to work up "slowly"! memtb
