Is the gun new or used? What type of ammo are you using(reloads/factory? It might be that your gun doesn't like the loads you are feeding it. I have found a huge variation between factory loads in 40sw. I now habdload for this caliber and it has made a huge difference. As well, you may want to try different sights on the handgun. Mine came with a couple of choices included and I couldn't believe the difference just changing the sights made (this doesn't make the gun fire any better, just the shooter)
There are times when the deer are simply not moving and you're forced to make something happen. Maybe you're up against a full moon or hot weather. This is when a silent drive to force deer to move should be considered.
By silent drive, you're not yelling and making a commotion to scare the deer. When deer are panicked, they're liable to bust out of the cover on a dead run, and any shot you get will be tough to make.
A silent drive is different. It means playing the wind to carry the driver's...
