Can anyone help me with trajectory (other than a rainbow) of a 460gr CP @1800fps out of a 32" BC barrel? Any info would be helpful and, thanks in advance for your input.

Hmmm, that's one that I've actually shot outa my 45-120!! I'd be glad to run figures for ya if I knew the BC of that bullet, but Cast Performance doesn't list it. Didn't find it at Midway, either.

fltcrkhilbily the closest i can give you is from the hornady handbook vol 11. 500grn bullet at 1800 fps zeroed for 100yds is - 12.7"at 200 -44" at 300 -99" at 400and -182" 500yds.with 460 grn bullet it will be a flatter shooting but this depends on your bullets sectional density and ballistic coefficient,you don't say wot type of bullet it is .i shoot a cast bullet 20 to 1lead tin mix it has ballistic coefficient of .443 it flat shooting when loaded with smokeless load at 1500 fps ,its a lee 500r some pics hope this helps.
