Ridge, I posted that up knowing that you use EXBAL and assuming you were familiar with that option of the program. I was explaining that feature to other members who may not be as versed in the program's useful tools...
I'm by no means a ballistic engineer, but I know that the b.c. of a projectile changes slightly as velocity bleeds off with distance. So either way, skewing b.c. OR velocity is just a means to an end...that end being getting your real world drops to match the EXBAL's theorized drops, based on the data you gave the program...
Its easy as cake to use the Trajectory Validation feature in EXBAL. If I'm shooting 4" high @ 600yds, I click the option, type 600 in the RANGE tab and 4.0 in the ELEVATION tab and viola, a new drop table is calculated when I hit APPLY. It just takes the guesswork out of picking the "correct" b.c. to get all your data to jive as efficiently as possible...
I wasn't disagreeing with ya /ubbthreads/images/graemlins/grinning-smiley-003.gif
