Q12.  In the Interior Ballistics program, after you load a gun file, the ‘Powder Water Capacity’ gets filled in somehow, as does the ‘Case Water Displaced By Bullet In Grains’ columns.  Shouldn’t the two added together equal the ‘Water Capacity’ in the gray information area above?  If not, why not?

Q8. I was wondering if your software gives the information for the distance to sight the gun in at so that you have the least amount of rise and drop out to some max distance. I have heard of software that will tell you that for a 30-06 it should be sighted in at 213 yards and that gives you the least amount of rise and drop for holding right on the target.
A8. Yes, one of the options on the Trajectory Tables drop down menu calculates the optimum zeroing distance for a point blank setting. The optimum zeroing point is where the bullet goes above the line of sight to the point blank amount and then down and crosses the line of sight which is the optimum zeroing point. The distance at which the bullet is below the line of sight by the point blank setting is also given. You may vary the size of the point blank setting and the default value is 3 inches above and below the line of sight.
