Well, that's pretty good. If you go for Aggressive Ballistics you'll probably lose Crowd Control, which is a really nice perk and makes up for much of the lost damage. You'd probably also lose Rodeo, which is one of the better perks in that slot for the Hammer. CQB + Rodeo should be manageable enough and you'll still pull a nice amount of 3HKOs, especially against groups. High Caliber Rounds are interesting... I imagine the stagger would be absolutely devastating against semi-automatic weapons. It's a good roll overall. It might be nice if you find a 2nd one to roll that for AB/Perfect Balance if you have a lot of extra motes but it's not worth rerolling the one you have. Also, nice roll of Perun's Fire. Rangefinder/Hammerforged/ORS1 pushes the Range to the highest possible.
