I have just been trying to make a ballistics drop chart for my rifle.
Its a .243 Tikka Super Varmint.
I am shooting Norma factory ammo and the box says the muzzle velocity is 1035m/s which equates to 3395ft/s. The ammo is 75grain hornady v-max heads which have boat tailed bullets and the ballistic coefficient for these bullets is .33.
The scope is mounted 1.5" above the barrel and I zero the gun at 100yds.
I have tried the Burger Bullet software that you have pinned on here and I have compared it to the other software that I have used which is here>>>Other software
What I find confusing is that they give massively differing figures
Can any of you guys enlighten me ???
