BC and Roskoe,thanks for the help, just so there is no confusion, I am aware that each rifle is different,but I am looking at a huge difference 3.357 is the longest I can get a cartridge to fit in the Tikka's detachable magazine. When I checked the lands on my cartridge, it came to 3.520 so I was well off the lands when I shot these loads...but to answer your other questions bc, there were no other signs of high pressure. So I will continue incrementally until I see other pressure signs. Ok lets put this post to bed.
