[QUOTE="MrButterpants, post: 189943, member: 10550"] Could be the barrel heating up causing an increase in cartridge temp and muzzle velocity, thus raising POI. Depends on how hot you got her and how long new rounds fed into the chamber got a chance to sit and cook in there. Could have been a change in you natural point of aim from fatigue....could have be a few other things.... If you weren't playing with it (adjusting knobs, optic power) and it just sat there under the mild recoil of a 223, I doubt the issue is the glass....unless it's a really crappy scope. If it was something associated with the optics I'd blame the mounts way before sending the scope back to get fixed.......but then again I'd be happy with that group :) Mileage may vary! What are the specs on the rest of the gear? [/QUOTE]
