I'm new to the program and need a little help. I was out this weekend shooting some loads at 200 and 300 yards. Of course the targets had 3 to 10 inches of drop from the bulls eye to the holes. On the large target in the program, one can't click to indicate the bullet hole because it is off the target. I did enter the X and Y and some of the bullet holes showed up down by or below the notes box. How do you guys handle this so it is meaningful?

Second, I put 200 yards in for the target distance even though my gun is sighted n for 100 yards. When I go to the trajectory, it shows 200 yards as the sighted in distance. I can change the target distance to 100 but that doesn't reflect the correct information. What do you do? Would a box for sighted in distance help?

Since I have exact bullet drops for my loads, it would be nice to be able to enter those at like 200 and 300 yards and have the program fit a curve based on that information to draw a trajectory curve for that specific load. That would give one exact MOA settings for intermediate distances. Could one also calculate an exact BC from this information?

1. The target is hard to locate groups on and confusing to many. Personally I keep the actual target in my load book and forget about the recording the group on the target in PB.

2. Target distance is the zero distance and the resulting range data is based on the zero distance. If you are zeroed in at 100 and the numbers don't match your actual fire there are many reasons why. Range temperature and component differences are one place to look. If you want to tinker with the trajectory and print out results try adjusting the BC. PB only uses one bullet design to compute the tables. Bullet design is not currently adjustable in PB but may be a feature in the next version.

3. If you have accurate drop information you need to adjust the Bullet BC to bring the program trajectory info in line.

I hope this helps you.

Safe shooting,
