i heard about useing antlers too call in deer .but do primos power doe and buck callers work well ?

I dont use primos but several of my buds do. They believe them to be good calls when used at the right time and at the right frequency. With your buck call if it is a grunt style try using a higher pitch grunt for bringing in more bucks to challenge. The low dominant grunt tends to keep the little guys away. But hey if you are just wanting the big boy on the block then by all meens try the low one lol.
