Anyone with an inline shooting 250 grain shockwaves, or powerbelts and 100 777 pellets with 209 primers know how high at 50 yds will make 100 dead on?

That is a hard question to answer the way it is asked. If you're sighted in dead on at 50 yards, you would be about 3-4 inches low at 100 yards, but the only real way to check this is to go to the range and shoot.

Cayugad's suggestion is the correct to approach you answer but here is a ballistic chart that might help a little more...

Thanks guys, reason I am asking is I borrowed my fathers CVA Kodiak for a friend to use, and it is 4" high at 50 yards. My father told me he could'nt find the paper at 100, and he ran out of time and never finished sighting it in. I have a place I can go and shoot 50yards on paper, I will make it 1 3/4" high at 50, and I should be on the paper at 100. My Omega is dead on at 100 so I know I am all set.
