I received a 6.5-20x44 BDC from Camera Land last week for my 20 Vartarg build. Since all the bits and pieces haven't arrived for the build I had to give it a try so i pulled the scope off my 22-250 and mounted it for a test.

After getting it zeroed and a couple quick test groups I decided to try test the tracking. Fired #1 and #2 at the center target. Then moved 12 clicks right and fired #3 and #4. Then moved 24 clicks left and fired #5, pulled #6 of course! Then with only one round left and frozen fingers I clicked 12 back to center and fired #7. I was out of ammo and frozen so will try elevation tracking another day. I'm happy with the results so far.

I tried to get a couple pics this morning of how the reticle is. This is my optics test "rock pile" located about 125 yards off my deck in my alfalfa field. First pic is set on 12x and second is on 20x. I found clarity to be very good and is very comparable to my Sightron's and 4200's.

Needless to say it was tough to get a good pic through the scope but this gives you a good idea for what it is like. Seems to be clear and sharp to the edge and I think the reticle will work nicely on the prairie dogs, not to cluttered.
