21” Sako triple deuce shooting 50 gr v-max is my go to calling rifle. During decoy season I shoot an AR quite a bit with 75 gr bthp. I get exits and they run further with the 75s. Most of the time you put a v-max in the chest of one, they don’t go anywhere but down. Along about the time I was thinking it was the perfect combo last year, I got a big broadside tear/splash. But that’s one out of a bunch. I’ve also shot cats with it and worked great on them too.
