No tricks here.....
I had a gruntcall and lost it years ago.....never called anything, so I haven't replaced it.
I've had the same half-full bottle of doe urine for 5 years, lol.
I did have a buck follow a scent-line I made one time....and I got him, but haven't used it much since.
I think the best tricks are to hunt with the wind, be quiet and be still.....I don't manage my own scent AT ALL. I think that deer can pretty much smell ANYTHING human no matter how hard we try to fool them. Ever use mink oil on your boots? How about the Rem-Oil on your rifle?
In fact, I do about everything WRONG, scentwise!!!!!
I smoked over a pack of cigs on the stand last weekend.
I bought some sliced hard salami for sandwiches.....they reeked, but were delicious!.
I shoot a VERY common Marlin 336 in 30-30.....with a Bushnell 4x sportview.....
I got my deer (med size 5pt buck 150 or so pounds) on Saturday (opener) morning. I'm grilling tenderloins as I type......
Life is GOOD!!!!
