Love spotting a buck and rattling him in.
Same here, even if he's not a "shooter". Lots of fun messing with them and seeing how they react. and how close they'll come in.
Last night I rattled in the best I've called in so far. A nice, but slightly broken up 10 point. Normally a shooter but I saw and rattled at his granddad a few weeks ago and was probably ruined for the season. Of course, his granddad was content with his does on the wrong side of the fence and didn't pay me much attention.
I have yet to experience any negative reactions from respectable bucks. On the other hand, most of my responses are from smaller and average bucks. Of the 10 or so I've rattled in this year, 3 were potential shooters which I passed on because hopefully I'll see one of them in another year or 2.
Very little downside from my experience and I've watched them come in from several hundred yards away and.killed a few of those in years past. I also include grunts and snort wheezes and "can" calls especially if I can see their reactions. Snort wheezes, as goofy as they sound, quite often gets them coming my way when rattling and grunts only get curious glances.
If does are present I'll usually.give them some time before rattling, but I will rattle if they're antsy and looking back in the brush from where they came though I'll usually tone it down, at least initially.
