trajectory issue

Post by river ecosystems » July 20th, 2015, 1:56 pm

I am shooting an ultra light with a 300 grain thor bullet, with 90 (units by volume) of Blackhorn powder. Can anyone give me an approximate drop at 200 yards if zeroed at 100. Actually I am about 6-8 inches high now at 100 yards but my rear sight cannot be adjusted any farther down. If that gets me on at about 200 yards, I will stay with this sight, otherwise I will have to replace it with a different rear sight. Thanks for the help.

If you can shoot at a animal at 200 yards, cant you shoot at a target at 200 yards? Anything else is just a guess and may differ from your actual results.

You could estimate the BC at .200, I doubt its much better in the real world vs inflated manufacturers specs. You still need a confirmed muzzle velocity. A fps reading at 100 yards would get you closer to actual drop and true BC.
