Velocity definitely increases from my limited experience. Check for case head separation and expansion as Expat mentioned. I'm not much for pushing limits on my firearms, mainly because I'm cheap and a sissy. Pushing max, also means elevated wear and tear. If your going for max horsepower at all costs, then shortened barrel life will be something to worry about. If there's a level of performance your chasing, that's possibly beyond what the cartridge is capable of, then another cartridge might be a safer bet in my opinion. Factory ammo always seems to do well for me, and even better with just a coal adjustment. Hard to say in your case, but for myself personally- I like things on the safer side. There's more than likely an ample amount of info on youtube, to explain how to best diagnose signs for excess pressure. I'd feel more comfortable trying out different projectiles.
