I have been having problems with my Sig 2400 and I know several others that have as well. Would not range an elk at 1200 yards in good conditions a couple months ago, last week wouldn't range 4 different coyotes from 700- 1000 yards. Going to sell it and go back to the new Gunwerks 2500. Anyone else have problems or have compared the Sig to the new BR2500?
