The old curse of the Handi ultralights..the barrel heats up a bit. I can get 3-4 shots off accurately before mine starts to "walk"..just a little. I don't consider that a problem though; of all the deer I've shot in about 63 years of hunting..only 2-3 took more than one shot, and then mostly for "insurance".
Even if I were to use a couple or 3 shots to down it (highly unlikely), the "finishing" shot would be at close range..so no sweat..
For trudging the woods..the .243 Ultra-light sure is a handy..Handi-rifle..
