I'm in the "Bulk" phase right now and ive always done 10x on all my exercises most of my life up until now.
I've been doing the heaviest I can (properly) do 6x in sets of 3 and I do feel sore the next morning, its not the same type of sore that I'm used to. Am I not working out hard enough or is this just a "different type of sore?"

Delayed Onset Muscle Soreness (DOMS) is not an accurate indicator of a good (or bad) workout. I wouldn't worry about it unless it's an unusually painful soreness (injury type). Just keep going and judge the effectiveness of your workouts by the progress you make, not soreness.
Don't think I'm really helping, but I'll throw in my .02
When I was lifting light w/ higher reps I'd get sore 2-3 days after working that group; since I've changed to heavier lifting to build up some mass I'm getting sore the next day. I didn't really change diet at all so that shouldn't be a factor
