Hot loads using Vihta Vuori

[Bandit01]

For my Glock 20 (10mm), I really wanted to experiment and feel some extreme power (recoil/flash). Currently I'm using 12.0 grains of 2400, and 180gr. HP bullet. On GlockTalk, someone recommended Vihta Vuori N350, saying that it'll create a "Cannon". Personally, I've never used an Vihta Vuori powders. Going to their website, using my set up with bullets, the Maximum load for that powder is: 6.8 grains. Has anyone ever used this set up? With this load, is it stronger than 2400?
