[QUOTE="Broz, post: 896937, member: 7503"] I won't call it a spike , but yes in my experience full cases or cases filled closer to full, as well as a compressed load can show higher pressure. This has been very evident when loading for the same rifle (300 win case) we can run 77 gr in a WW or RP brass but with the same powder lot and same bullet lot in RWS brass we max out at 74. In one instance we tried going up to the same 77 gr load and it showed over pressure and even leaking primers. I have also seen it work this way when sinking the bullet into a close to full case. It was ok at .040" off the lands with a max load. But sinking the bullet showed more pressure and a velocity increase. So it is worth considering when close to max on a load a change closer or farther off the lands could create more pressure. So I just don't count on moving away from the lands will reduce pressure all the time. Jeff [/QUOTE]
