Thanks for all your thoughts, fellas.

<br>IIFID, I've used the 2-7 for a lot of years, and appreciate it's compactness, but could have used more power on a couple occasions where the lighting wasn't right. Twenty some years ago, when I bought my first 2-7, it was the right choice, but find it lacking in some situations now.
<br>
<br>After comparing scopes in very low light, the HD is clearly the right choice for MY eyes. Will try the 4a in near future. Haven't done any long range blackbird hunting since about puberty, so 2" subtension @ 500yrds, shouldn't be too significant.[Linked Image]

<br>Coincidently, this scope, that subtends .4" @ 100, was on a 375 Wby for fireforming, and groups at 100 yrds were at .4" or just under. Wishfull thinking, no doubt, but will post results,if they happen to shrink by .2" when a standard duplex is used.[Linked Image]

<br>No supersition here, but this thing was sitting at thirteen posts.
