I can only speak for myself here,.... but when I begin working up loads for a particular rifle, I start at 25 yards off a bench.
Once I'm getting one-hole groups at 25 yards, I adjust my sights to hit center of bull at 25 yards.
After my load and sights are getting one-hole groups in the bullseye at 25 yards,.... I then move out to 50-75-and 100 yards increasing my powder charge until my groups start to open up, then I back down a few grains. Checking a few fired patches as you're working up your loads, can prove invaluable.
I like hunting loads that group 2" high at 50 yards, which (on average) results in them hitting about 1"-2" low at 100 yards (both of which are well within the "kill zone" of deer sized game).
None of my rifles have barrels as short as your Bobcat, so your mileage may likely vary from mine.
