Looks as if Lapua loads a couple of sport shooting bullets to two different velocities in 6.5x55: https://www.lapua.com/cartridges/6-5x55-se/Kind of reviving this old thread but in the curious case of the 6.5x55 swede you should look at SAAMI specs per cartridge and you will come away with one outstanding question> WHY? 45k when so many standard cartridges are at 60k or higher? Everything is based on fear of shooters using in old rifles not modern rifles even though they say it. I know of many who run with 58-60K pressures as run through quickload. http://www.lasc.us/SAAMIMaxPressure.htm
I am just suggesting that there is not a manufacturer out there that is going to put themselves in position of potential litigation by publishing loads that are over either SAAMI or CIP pressure specs. That is the conundrum of the 6.5x55 swede.
