If you tried the 29 grain boatails from Kindler, it may change your mind, with a BC of .240, ain't nothing like the 'ol 25 gr. flat bases. These work in a 10 twist. His 30 grainers have a BC of .270, but take a 9 twist.

For comparison:

40 gr. V-max is .200
50 gr. V-Max is .242
55 gr. V-Max is .255

A 17 Rem will run the 29's at 3850.

Compare that to your 223's, or 22-250 for that matter, for wind drift. (75's needn't apply)
