The Hawke BRC has several pre-set reticule and calibre options.
However, you will need to change the "E.D Value" box to the correct ballistic coefficient of the pellet you're using to get a good trajectory match.
The default ED Values do not equate to your average pellets in the respective calibres.
You may well find (as I have) that 7x mag is a better choice for most .22 pellets at 12ftlb, rather than the 6x that is recommended.
