Re: Trajectory Validation ??

I just used your numbers that you gave us on this site. Using JBM calculations, selecting the 240 SMK from there data bank, also using the one labeled Litz (test firer of many different bullets using BC data) came to 42.3 MOA at 1325. This is with a temp of 72 degrees, Baro 29.76, Humidity 40%, and 950 Altitude in Pennsylvania. You may want to take a look at this data and compare with exbal.

Good Luck,

Re: Trajectory Validation ??

Just for clarification, the spot you would normally enter in the BC is marked as 1, just to put in a number. W/o anything in that slot, the calculation won't happen. It is predetermined by the projectile you chose as well as the G rating. You just need to put in the pertinent information for you shooting conditions.

When we use the JBM calculations, things seem to be right on when we put the right data in.
