Start at twenty five yds and then fifty then one hundred.

Remember that a DR isn't a bolt gun! DO NOT let a rest contact the rifle. Keep your hand on the forearm and the stock resting on your shoulder at all times whe pulling the trigger. I like to sit totally upright when on a bench so my body reacts just like shooting off hand. (Off hand is best)
One of the members her has taken a coyote at just under 300 yds.. hitting it twice!
I wouldn't hesitate to take that caliber out after anything in Canada or Ak. Parka squirrels on up to big white fuzzy critters!
Now lets see some pics of that rifle.
Load up and go out an play!
