Re: 300 BO
I don't think the elcan's come with a subsonic bdc. The canadian's here in douchbagastan all carry the elcan 1x/4x and seemm to like it. The glass is great, but to me it seems bulky for such little utility. Leupold is the only manufacturer I know of making a 300 Blk subsonic bdc. I have a 1-4x20 Leupold on my SBR and a 3-9x40 Leupold on my 16" BLK. I've been happy with both of those set ups. The 3-9 is a Mk4 with the M2 (?), 1 MOA clicks which makes it easy to go from supersonic to subsonic when in the field. If I remember correctly, I have a 100y supersonic zero with dope for 100-160 yards subsonic, somwhere in the neighborhood of 12 MOA for 100 up to 17 MOA for 160.
