I need some help with external ballistics. I have tried to use the on line calculator over in the Beartooth Bullets section, but it won't work. I don't know how to use it for sure, then my computer has been giving me a consistant run of 502 and 504 errors lately. So I can't get anything done.
My goal. I want to sight my 20" Rossi in at 25 yards, (the only range I have available to me) with it shooting high enough that it will be close to on at 100 yards.
Gun:......Rossi Puma 20" barrel
Sights:...Front; aproxamatly .65" from center of bore to top
.............of sight. Rear; ?
Ammo....Winchester 255 gr lead.
Velocity...1100fps (aproxamatly)
BC..........0.153
If this rifle / load is sighted for a 100 yards zero, how high will the bullets hit at 25 yards?
If there is any more infor needed to calculate this please let me know.
Thanks in advance for any and all help on this matter.
