Home Forums Hunting & Shooting Hunting Optics Sighting in a BCD scope for a 257 weatherby?

Here is my routine for 2nd focal BDC. After you get your rifle sighted in for whatever range you want, put a few rounds into the 400 yard target. Then mark the target with a horizontal line thru the center of your group using a heavy marker broad enough you can see thru your scope.

After you get back to your shooting rest, twist the power selection ring until the stadia line you want is on the line you marked on the target. This will give you the power setting for your scope to use on a 400 yard shot. It will probably be around 9x or 10x. using a 250 yard zero.

Then repeat the process for power settings and stadia lines for other distances.
