The 243 will be a dandy backup gun for the 223 and 30-06. I wouldn't hesitate taking big game (bigger than deer) with my 243. I use my 243 as a backup to my 7mm Rem mag. I actually use my 243s for all my varmint shooting. I have +/- 3500 rounds thru the tube in my Tikka and its still shooting good. These are all hot handloads too I might add.
I'm a Leupold/Nikon guy myself. I have a few Leupold VX-IIs, a few Vari-Xs, a Mark 4 tactical, and a few others. For Nikons the Buckmaster 4.5-14x40 is one of the best buys in optics in my opinion. It is just as bright in low light as the Leupold VXIIs, and its better than my Zeiss Conquest in low light. The one thing I don't care for with the Nikon is the adjustments, they aren't 1/4" as stated. Then again I have one of the first ones to come out, and I have officially beat that thing to hell an back, but it keeps going.
I have a buddy that bought the Ballistic Plex Burris you speak of, only I have no experience with it yet, and he hasn't even fired the AR15 he has it mounted on. As for illuminated reticles, I also have no experience. I see them as one more thing to fail in the field, so I avoid them.
Thats what Iwas thinking about the illuminated reticles too, the battery would end up dying right when a big buck steps out at dusk.
I have looked through the Ballistic reticle scopes, and for me, there is just too much going on with them. I would rather have a duplex or dot and then just get target turrets calibrated for my load. Just my opinion though
Rammer, thats awesome you have that many rounds through yours. I didn't think they would last that long.
