RE: rattling
I have used it with minimal results in NH and Mass. I have brought bucks in from time to time, but the percentage of tries to success is very low. Maybe 1 buck to 40-50 rattling sequences. In the early season it is MUCH easier to rattle in Bull moose than deer, that's for sure.
That being said, I have shot 2 deer that were a result of rattling. 1 was a trolling rattle, the other the buck was out of range but seen and I used it to bring him in. Which is the main reason I still bother to carry them in, I don't rattle much at all now.. but if I see a buck that is just way to far away and he's not coming any closer I will use the horns as a last ditch effort to lure him in if the grunt tube and "can" don't work.
In Iowa last year though ... I rattled multiple bucks during the rut to within a 100 yards of the house I was staying at. I'd recommend saving the rattling for the areas with deer crawling all over them, and use them more as a last attempt to turn a buck here in the Northeast. I've seen as many deer around here walk away as come in to them.
