FWIW;
My factory 7x57 chambered Husqvarna rifles really like 150 gr bullets. Either the Norma factory load or a handload that a friend of mine made up using the Nosler 150 gr. Partition that is a little warmer than the Norma.
I think that barrel twist is very important factor in the 7x57. The same Husqvarna rifle that shoots .75" 3 shot groups with the Norma factory load will keyhole a 175 gr. bullet.
