I have several Bushnell Custom 3x7 scopes with the BDC. Most have the W1 dial for 50-200yrds. One has the W2 dial for 50-175 yrds. I would think the W1 (200yrds) would be the 22 mag dial and the W1 (175 yds) would be the 22 lr dial. However I have way more W1 dials and would think the 22lr dial would be the most popular. So what I need to know is which dial is 22lr / 22 mag?
