So how much of a velocity increase are we talking about?
We'd need to get the velocity from 1180 up to 1490 feet per second. ..

Hm, what I'd do is divide 1180 by 7 getting 168 and some decimals. Then I'd multiply that by 2 and add it to the 1180 getting 1517 (and some more decimals). Or even more simply I'd multiply 1180 by 1.2857 and get 1517.
The situation you've outlined is one where damage increased is linear with velocity increase.
