I believe hunting pressure has a lot to do with it.
When I started bowhunting in 87 The only deer grunt call you could buy around here was the woods wise
grunt and bleat. I used it with success. you could not run a deer off with it. Everyone thought I was weird for using it. Nowadays everyone owns a grunt call and a pair of horns. I used to have good success rattling also even with our buck to doe ratio way out of whack. I run more deer off with a grunt tube than I call up now. I dont ever rattle around here anymore. I went to south arkansas bowhunting last year. I tried to grunt at bucks, snort wheeze at bucks, bleat at bucks, none of it worked. They would tuck tail and run every time. The hunting pressure was more than any where I have ever been. Your best bet was to slip in like the wind and remain undetected.
I went to Kansas last year and had great success rattling and grunting, bleating , and snort wheezing.
If you put the horns together you better start looking around. I contribute this to lack of pressure during the rut. Bowhunting only during November. Man it was nice.
