I am looking at building another rifle and want a cartridge that I can use for pretty much everything. I built my last one in 7X57 on a Spanish Mauser and have been pleased with the round but have kept loads low because of the action used. After doing some research I've found that SAAMI keeps the 7X57 quite tame(but effective) at 51,000 psi and velocities at those pressure are decent. My question is, with a strong enough action (98 Mauser, Rrem 700, Ruger #1), can you safely exceed SAAMI pressures to get the velocity and trajectory up just a tad. I guess the limiting factor here is will the brass stand it if you run pressures up to 60,000 psi. I know someone here has tried it and I would like to hear their stories. Feel free to correct me if my information is bad or just to smack me around in general. Thanks in advance!!!
