My varmint handguns have either a Burris 3x9LER or the newer 3x12LER on them. These are Contenders in .218Bee, .221Fireball, and .223Remington. Also have Encore barrels in: .22BR, .225Winchester, and .22-.250Remington. I used rifle scopes on the scopes with little recoil but still like the eye relief of the Burris scopes so I went to them. Have a great time with picket pins, p-dogs, and coyotes. :-)
