Thanks for the replies.
The blackout issue has me concerned because I have had it happen on a couple of Leupolds with small exit pupils, but they have both been 4.5 x14 x 40's.
Both my LR M3's work great after getting through several bad ones early on, I really like them.
I have looked through some Nightforce scopes and liked them [especially the reticle choices] but the weight and size are excessive for this project I think. I have not seen the new 2.5 x 10 though.
I know the early illuminated reticle LR Leupolds had problems with durabilty, I called Leupold when I was looking at trying one on a bolt gun and their forever warranty did not cover the illuminated reticle, it only had one year. I am hoping the MR/T has a "next generation" illuminated reticle that holds up better. I am concerened with there being no positive off position, as I don't know what the battery life on these are, looks like that would be an easy design feature to add.
I am also torn between the M3 and M1 version. I have 2 of the M3's on .308's and the elevation wheel matches my round out to 800 yards almost dead on. The only M3 wheel I see for the .223 is a 55 grain bullet at 3200fps. This will be way off the 77 grain round I want to shoot. I know I can just dial in the MOA but I like being able to dial in the yardage without looking at my tables [too many tables and too short a memory to remember them all]. I also like not being able to get a revolution off with the M3.
Thanks, Mike
