Pistol ammo is cheaper. Broadheads are getting expensive! I haven't had to use a pistol yet tho.
For those using a sidearm for grouse, do you use birdshot? I thought about getting some for my 9mm but read that it wouldn't eject.
.22 is best for grouse. I’ve never try one of those 9mm shot rounds but I suspect they are more of a gimmick than anything.
