request trajectory predictions
i was sighting in my TC Encore today after boresighting a new scope. group was 4 inches high at 25 yards. what would be the predicted point of impact at 100 yards? i'm shooting 150 grains (3x50 pyrodex pellets) with a saboted 240 grain cast bullet (.430). thanks for any opinions.

RE: request trajectory predictions
4" high at 25 yards... according to the ballistic calculator you should hit about 9" high at 50 yards, 17 inches high at 100 yards, because the only way I could get the rifle to hit four inches high at 25 yards is to have it dead on at 380 yards.
If you have a nice group at 25 yards, that's a great start. Now bring that group down to the top of a 1" bull at 25 yards and they should also hit almost dead on at 100 yards. If you want to shoot real long distances then sight in 3" high at 100 yards.
