Well here are a few quick calculations to help out (if you want)
v = 293.33 ft/s
rho = 0.0023 slugs/ft^3 (1000 ft elevation)
Then depending on your size (S, ft^2) and your drag coefficient (CD), this is how much drag you will have:
CD__S__D__
0.01 4.0 3.972
0.02 4.0 7.944
0.03 4.0 11.916
0.01 7.0 6.951
0.02 7.0 13.902
0.03 7.0 20.8531
0.01 10 9.93
0.02 10 19.8601
0.03 10 29.7901
