LOL the 505 Gibbs is actually an easy cartridge to shoot. There are two key ingredients, gun weight and stock shape. However stock shape is by far and away the most important part. My 505 is light in comparison to other 505's but the stock shape is so good now after Ross Waghorn re-shaped it that the fact it is slightly lighter doesn't matter one bit. Sure you know you are shooting a big gun but it is fantastic to shoot.

The 2300 fps story is also bullshit, that was an advertising fantasy, 2150 fps is actually correct.
