Most powerful is a point of view. If by most powerful you mean it does most damage, then yes, it's very powerful. But it's not always going to be the most effective killing weapon. Blunderbusses are extremely slow to reload, and are known to miss quite often. But when it does hit, it's devastating. But the point is, which is more effective: A sabre that hits every time very quickly? Or the Blunderbuss that has a hard time hitting, and is slow to reload, but has enormous power?

Consider this: I've seen a lot of invasions, and since the new weapons have come out, I've seen swords to be more effective in the long run than any form of gun.

Blunderbuss only miss on enemys lower level then you, i have no problem shooting darkhart, so far i've only missed about 4 times, after shooting at him over 2000 tims.

I still think, for an invasion, a rifle is the best ranged weapon. You're able to take out targets long before they get close enough to do any damage to you. Sure, it takes a few seconds to reload - but, it's well worth it to have a full health meter. And, as a bonus you're only engaging one mob at a time, eliminating the chance of getting ganged up on by a bunch of bad guys. No fear of keg runners - And, it's the only way to deal damage to JR while outside the range of his staff.
